Explain at least three ways in which a mutation in an individual's DNA could occur, and describe at least 2 effects a mutation could have on an individual's traits.
Answer:
Explanation:
Three ways in which mutation could occur are
1) If an error occurs during DNA replication and it's not corrected in time by DNA polymerase.
2) If there is a deletion of a base(s) in the sequence of the DNA. The deletion of a DNA nucleotide/base could also cause a mutation as that could affect the formation of an enzyme or protein useful in building and/processing certain body parts/processes.
3) Thymine dimerization: Thymine dimers are mutations that prevent DNA from replication or even transcription hence preventing a cell from undergoing division (hence causes cancer). They are formed when covalent bonds are formed between the bases of a DNA sequence (somewhere around the carbon-carbon double bond).
The two effects are
1) It could cause cancer as described in (3) above (in the case of thymine dimer)
2) It could lead to deformity in an individual because of the gene that is supposed to code for the last finger has a base deletion, that could eventually lead to the absence of that finger or a shorter or "strange" finger.

Explanation:
Viruses are one of the leading causes of illness in the world
True
False
Answer:
True
Explanation:
Answer:
False, but be sure you read what follows.
Explanation:
False: Heart disease and Most Cancers are not viruses. Or at least as far as I know. However complicating the issue is the fact that after a viral infection, heart disease can develop.
Cancer is another example, and the answer again is not black and white. 16% of all cancers can trace their beginnings to a bacteria or virus. That leaves 84% whose beginnings are not that clear.
The question is not black and white. I'd be careful how you think of it. If something is a complication, is that a direct cause? I still think the answer is false, but don't be surprised if your instructor disagrees. Move on to something a little less black and white.

how does each of your mutations affect the amino acid sequences? Are the mutations missense mutations, silent mutations or nonsense mutations?
a. Point mutation?
b. Frameshift-insertion?
c. Frameshift-deletion?
Answer:
the correct answer is B Frame shift insertion
Explanation:
plz give me brainiest
Frameshift-insertion mutations affect the amino acid sequences.
Thus, The insertion or deletion of nucleotide bases in amounts that are not multiples of three is referred to as a frameshift mutation in a gene.
This is significant because a cell reads the genetic code for proteins in groups of three nucleotides.
These so-called "triplet codons" each stand for one of the 20 different amino acids that go into making a protein. This normal reading frame will be disrupted by a mutation, which will result in an inaccurate reading of the entire gene sequence after the mutation.
Thus, Frameshift-insertion mutations affect the amino acid sequences.

B. the monomer is destroyed
C. The monomer is permanently part of the polymer
The monomer can be reused once the polymer is deconstructed. So, the correct option is (A).
What is Monomer?A monomer is defined as a molecule which can react with other monomer molecules to form a larger polymer chain or three-dimensional network in a process called polymerization.
These are described as atoms or small molecules which bond together to form more complex structures known as polymers. There are four main types of monomer which include sugars, amino acids, fatty acids, and nucleotides.
Monomers can also be reused again when the polymer is deconstructed.
Thus, the monomer can be reused once the polymer is deconstructed. So, the correct option is (A).

An agricultural biologist was evaluating two newly developed varieties of wheat as potential crops. In an experiment, seedlings were germinated on moist paper towels at 20ºC for 48 hours. Oxygen consumption of the two-day-old seedlings was measured at different temperatures. The data are shown in the graph below. In a second experiment, variety A seedlings at both temperatures were treated with a chemical that prevents NADH from being oxidized to NAD+. Predict the most likely effect of the chemical on metabolism and oxygen consumption of the treated seedlings. Explain your prediction.
Answer:
The definition is listed in the clarification segment below, and according to the present circumstances.
Explanation:
It undergoes different morphological as well as biochemical modifications mostly during germination. Product contains nutrients and even some hydrolases such as energy, carbohydrates. Owing to the availability of phytic compounds, the seed coat seems to be very durable in nature. Hydrolytic enzymes launch their function by consuming oxygen throughout order to remove this hard coating. In several other processes, including the electron transport system as well as the Kreb process, oxygen also becomes necessary.
The initial phase of germinating seeds requires anaerobic environments where even the enzymes dehydrogenase can function. The subsequent dehydrogenase enzyme brings the electron throughout the electron transport system from either the base to oxygen. Unless the oxygen frequency is compared with varieties A and B, it can be seen through the analysis that variety B actually absorbed more oxygen. Oxygen intake rates are also depending upon period.The impact of temperature mostly on absorption of oxygen seems to be present. Shift the supply at low temperatures have a low intake of oxygen, while varieties grown over extreme temperatures use much more oxygen. The metabolism of such a seedling is influenced by temperature. Metabolically active young plants display a larger intake of oxygen.In order to fit all of our DNA into our cells, it is wrapped around histone proteins and then...

c
Kinetic energy is increased
d
It does not change its physical shape
Answer: C
Explanation:
When heat is added to a substance, the molecules and atoms vibrate faster. As atoms vibrate faster: the space between atoms increases: The motion and spacing of the particles determines the state of matter of the substance: The end result of increased molecular motion is that the object expands and takes up more space.
1. Describe cell differentiation and include any environmental factors that play a role in gene regulation. 2. Explain the types of cells produced by meiosis. Include in your explanation the number of daughter cells produced, the number of chromosomes in each and whether they are diploid or haploid.
Answer:
1. Cell differentiation is the process whereby simple generalized cell develop into cell with specialization in function and structures. Some environmental factors that affect gene regulation include diet and nutrition, temperature, oxygen levels, humidity, light cycles, and the presence of mutagens.
2. Gametes or sex cells are produced in meiosis and they have haploid number of chromosomes. In humans, the haploid number of chromosomes is 23 chromosomes.
Explanation:
Cell differentiation is the process whereby simple generalized cell develop into cell with specialization in function and structures. During the initiation of cell differentiation, transcription factors activate only the genes to be expressed. Some environmental factors that affect gene regulation include diet and nutrition, temperature, oxygen levels, humidity, and the presence of mutagens(factors that cause mutation).
Differentiation occurs in zygotes numerous times resulting in the formation of a fully developed organism. Also in unspecialized cells known as stem cells, differentiation occurs leading to the formation of various cells of the organs and tissues of the body.
2. Meiosis is a type of cell division in which gametes or sex cells are produced. A single cell divides twice producing daughter cells with half the number of chromosomes present in the parent cell. In humans, the chromosome number is 46. After, meiosis, the haploid number of chromosomes produced is 23.

What holds amino acid chains within a protein in shape?
Answer:
Proteins are the end products of the decoding process that starts with the information in cellular DNA. As workhorses of the cell, proteins compose structural and motor elements in the cell, and they serve as the catalysts for virtually every biochemical reaction that occurs in living things. This incredible array of functions derives from a startlingly simple code that specifies a hugely diverse set of structures.
In fact, each gene in cellular DNA contains the code for a unique protein structure. Not only are these proteins assembled with different amino acid sequences, but they also are held together by different bonds and folded into a variety of three-dimensional structures. The folded shape, or conformation, depends directly on the linear amino acid sequence of the protein.
