Answer:
1. The central dogma of molecular biology is DNA >>transcription>> RNA >>translation>> protein
2. DNA replication refers to the genetic process of generating two identical DNA molecules from one DNA sequence. Recombination refers to the exchange of genetic material (DNA) between non-sister chromatids during cell division (meiosis)
Explanation:
Gene expression (also known as transcription) is the process by which a specific fragment of DNA called gene is used as template to synthesize an RNA molecule, usually a messenger RNA (mRNA), which is in turn used as template to create a protein. This final product (i.e., the protein) has an effect on the phenotype of the individual. The DNA template is a single-stranded ordered polynucleotide chain composed of four different types of nitrogenous bases: Adenine, Thymine, Guanine and Cytosine. In the complementary RNA molecule, Thymine bases are replaced by Uracil bases. Moreover, DNA replication refers to the process by which cells duplicate their genetic material before cell division (either mitosis or meiosis). During this process, both DNA strands are separated and each one is used as a template to synthesize a new DNA molecule. Finally, recombination or crossing over is a process where non-sister chromatids exchange genetic material during meiosis I (Prophase I). Recombination is known to increase genetic variation in resulting meiotic cells.

what's assembled during the second step of protein synthesis
Answer: Translation is the second step in protein synthesis. It is shown in Figure below. Translation takes place at a ribosome in the cytoplasm. During translation, the genetic code in mRNA is read to make a protein. In the first step, called transcription, the genetic code in DNA is copied by RNA. In the second step, called translation, the genetic code in RNA is read to make a protein. A mutation is a change in the base sequence of DNA or RNA.

Answer: 1. On a biological level, the main difference is that bacteria are free-living cells that can live inside or outside a body, while viruses are a non-living collection of molecules that need a host to survive. On a biological level, the main difference is that bacteria are free-living cells that can live inside or outside a body, while viruses are a non-living collection of molecules that need a host to survive. 2. The lysogenic cycle is a method by which a virus can replicate its DNA using a host cell. A bacteriophage, or bacteria virus, injects its DNA into the bacteria. ... The DNA is then replicated when the bacteria undergo cell division. 3. A lysogenic virus can remain inactive for a period of time. In lysogenic infection, viral DNA gets integrated with the host cell's DNA, where it is copied along with the host cell's DNA when the host cell replicates. ... It then removes itself from the host cell's DNA and enters the lytic cycle. The lytic cycle: The phage infects a bacterium, hijacks the bacterium to make lots of phages, and then kills the cell by making it explode (lyse). 4. So were they ever alive? Most biologists say no. Viruses are not made out of cells, they can't keep themselves in a stable state, they don't grow, and they can't make their own energy. Even though they definitely replicate and adapt to their environment, viruses are more like androids than real living organisms. brainliest?
Explanation:
A segment of a DNA strand is shown. AGGTCAGG
a. What is the complementary DNA strand?
b. What is the mRNA strand?
c. What amino acids are produced as a result (use the codon chart to help you)
Answer:
b. messenger ribonucleic acid
a. The complementary DNA strand is the sequence that pairs with the given DNA strand. In DNA, adenine (A) pairs with thymine (T), and cytosine (C) pairs with guanine (G). Therefore, the complementary DNA strand of "AGGTCAGG" would be "TCCAGTCC".
b. The mRNA strand is synthesized based on the complementary DNA strand. In mRNA, thymine (T) is replaced by uracil (U). Therefore, the mRNA strand corresponding to the given DNA sequence "AGGTCAGG" would be "UCCAGUCC".
c. To determine the amino acids produced, we need to identify the codons (groups of three nucleotides) in the mRNA strand and refer to a codon chart (also known as a genetic code chart). Here's an example of how the codons in the mRNA strand "UCCAGUCC" can be translated:
UCC (Serine)
AGU (Serine)
CCU (Proline)
Therefore, the resulting amino acid sequence would be Serine-Serine-Proline.

While Rebecca at her locker she can hear students coming from around the corner. Which wave interaction explains why she can hear them
Answer:
Diffraction
Explanation:
Diffraction is the key explanation why we can hear sounds around corners but not see them. As compared to light waves, sound waves have much longer wavelengths, making diffraction effects much more visible. When the size of the object that the wave is diffracting around is about the same as the wavelength of the wave, diffraction effects become very visible.
Sound has a wavelength of 1 m, while light has a wavelength of 0.1 micro m. Reflection is a secondary reason. Sound waves bounce off walls in a specular way, allowing them to bounce around corners, but light bounces off walls in a diffuse manner.

A large population of Yellow perch lives in the East river. The Walleye is a larger fish that eats the Yellow Perch. Despite lots of prey all the Walleye have moved from the East river to a new river. What most likely caused the Walleye to move to a different river?
(A)There is a lack of food in the East river which caused the Walleye to move to a different area.
(B) The Walleye are no longer able to catch the Yellow Perch and need to move to a different area.
(C)There is climate change which has caused the resources to decline in the East river.
(D) There is pollution in the East river that the Yellow Perch are adapted to but the Walleye are not.
Answer:
(D) There is pollution in the East river that the Yellow Perch are adapted to but the Walleye are not.
Explanation:
To ensure survival and cntinurd sustenance in an environment, there is need for an animal to posses certain features which would enable her cope with the conditions of the environment. The ability of animals to successfully live and survive in an environment is made possible through adaptation as the animal's adaptive features ensures the animal is able to live through and cope. If the adaptive features aren't suitable for such environment, then migration has to occurs, leading the animal to find a more suitable environment for survival. In the scenario above, the East river was presumed to be a good habitat for the Walleye and Yellow Perch, in spite of the available and abundance of food, the Walleye migrated, which is most likely due the fact that the Walleye lack the adaptive features to survive in the East river probably due to pollution which the Yellow Perch is well adapted to.

3.
C. G-A-C-T-A-T-C-C-G

d. G-A-C-A-T-C-C-G
Which sequence represents an inversion
mutation?
Answer:
1. Given the DNA sequence: G-A-C-A-T-T-C-C-G, the complementary sequence is C-T-G-T-A-A-G-G-C (a).
2. Given the DNA sequence: G-A-C-A-T-T-C-C-G, the insertion sequence is G-A-C-G-A-T-T-C-C-G (b).
3. Given the DNA sequence: G-A-C-A-T-T-C-C-G, the deletion sequence is G-A-C-A-T-C-C-G (d).
4. Given the DNA sequence: G-A-C-A-T-T-C-C-G, the inversion sequence is G-A-C-T-A-T-C-C-G (c).
Explanation:
The complementary sequence of DNA is a sequence of complementary nucleotides. The complement is a nitrogenous base that correctly pairs with the base that is given. In DNA, Adenine (A) correctly pairs with Thymine (T), and Guanine (G) with Cytosine (C). Therefore, the complement of A is T, and of C, is G.
The given sequence complement would be C-T-G-T-A-A-G-G-C since it's a sequence of bases that correctly pairs with the given sequence, G-A-C-A-T-T-C-C-G. [ G-A-C-A-T-T-C-C-G | C-T-G-T-A-A-G-G-C ] Notice that the first base in the sequences is G and C respectively. The next two are A and T. The paring is such that C complements G, and that A, T.
2. An insertion sequence is one in which there is an extra added nucleotide or codon. [ G-A-C-A-T-T-C-C-G ] Notice that there are three Triplets in this sequence. In a case where there is an extra nucleotide(s) or codon(s), such is termed an insertion mutation. When the given sequence is compared with the sequence in option b, G-A-C-G-A-T-T-C-C-G, you can observe an extra nucleotide [G - the fourth letter in the sequence]. Therefore, this sequence is called an insertion sequence.
3. Deletion mutation is an error in the DNA replication process that removes a nucleotide(s) from the genome. Hence a sequence that has a nucleotide(s) removed from the original sequence is called a deletion sequence. With the given sequence, G-A-C-A-T-T-C-C-G, the deletion sequence to this is G-A-C-A-T-C-C-G. [G-A-C-A-T-C-C-G ] Notice that one of the nucleotides, T, is missing.
4. Inversion mutation is a chromosome rearrangement in which a chromosome is reversed end to end. This involves breaking and rearrangement within a sequence. With the given sequence, G-A-C-A-T-T-C-C-G, an inverted sequence is G-A-C-T-A-T-C-C-G. [ G-A-C-T-A-T-C-C-G] Notice the first two nucleotides, of the second codon (....-T-A-T-...). The original sequence has....-A-T-T-...., but the new sequence here has...-T-A-T-.... Suggesting that the first two nucleotides were broken and rearranged end to end.
