Which is a point mutation and not a frameshift mutation?
mutagen
insertion
deletion
silent
Answer:
The correct answer is D. Silent
I can assure this is the correct answer because I took either the test or review, I don't remember but yeah I know its correct also, because of the other person so be sure to say thanks to them before me!
Hope I helped! <3
A silent mutation is a point mutation and not a frameshift mutation. Therefore, the correct statement is option D.
What are point mutations?Mutagens are agents causing mutations in DNA sequence. Point mutations are due to a change in a single nucleotide base in a DNA sequence and frameshift mutations are due to changes that are the result of the insertion or deletion of nucleotide bases, thereby, shifting the reading frame of the sequence and the way is changed in which it is translated into a protein.
A silent mutation is a point mutation that does not change the amino acid sequence of a protein, as the mutated codon still codes for the same amino acid, thereby, not affecting the function of the protein.
Insertion and deletion mutations are frameshift mutations as they alter the reading frame of the sequence which results in a completely different amino acid sequence.
Therefore, the silent mutation is a point mutation.

To study the mechanism of DNA replication, Meselson and Stahl labeled both strands of a DNA molecule with nitrogen-15 and then tracked the location of this label after one round of replication. which composition describes the products they found?
A. Both double helixes were composed of small segments of the
original strands and small segments of new strands.
B. Both double helixes were composed of large segments of the
original strands and large segments of new strands.
C. Both double helixes were composed of one original strand and
one new strand.
D. One double helix was composed of the two original strands, and
the other was composed of two new strands.
Answer:
The answer is C.
Explanation:
The original strand is split apart in half, those are added to two new strands. Which makes each double helix part original and part new strand. This is the correct answer, as I just took the test.
3. What challenges do older generations face?
Answer:
Health problem. As aging occurs, the more weak and unstable the body gets.
Unporportionate generation distribution. Some older generations are larger than the ones that precede it, thus, making it harder to have the proper resources to take care of older generations.
Technology. It is harder for older generations to be up-to-date on technology. This can make it harder for older generations to function in society properly.

Hope this helps!
There are 64 possible combinations of nucleotides to form a given amino acid.
The genetic code to add an amino acid is the result of a triplet of nucleotides or codons. In consequence, there are 4^3 possible combinations of nucleotides in a codon.This number (64) gives us the number of different codons that can be found in the genetic code.In conclusion, there are 64 possible combinations of nucleotides to form a given amino acid.

The pedigree below depicts a dominant trait. What is the genotype of individual I-1 (use the letter A for a dominant allele and a for a recessive allele)? How did you come to this conclusion? Using your best grammar, write 3-5 sentences.
A pedigree chart is a diagrammatic representation showing the occurrence and appearance of phenotypes of a particular gene/traits and its ancestors from one generation to the next establishing relationships between individuals in a family.
Using the letter A for a dominant allele and a for a recessive allele, the genotype of individual I-1 is Aa.
In the key pedigree nomenclature, an individual marked with the black ink is affected with the trait (and this trait is dominant - A). Looking at the F1 generation, there are males affected and females as well. For inheritance of the trait, just one copy is enough to become affected. Therefore, the male parent is heterozygous for the trait and the female normal (aa) to enable the production of both affected and non-affected individuals.Learn more about pedigrees: https://brainly.com/question/318443

The most abundant in the body is cells.
What do you mean by cells?Cell is the smallest unit that can live on its own and that makes up all living organisms and the tissues of the body. A cell has three main parts: the cell membrane, the nucleus, and the cytoplasm.
Moreover, they provide structure for the body, take in nutrients from food, convert those nutrients into energy, and carry out specialized functions. Cells also contain the body's hereditary material and can make copies of themselves. Cells have many parts, each with a different function.
There are two main types of cells: prokaryotic cells and eukaryotic cells. Prokaryotic cells include bacteria and archaea. Prokaryotes—organisms composed of a prokaryotic cell—are always single-celled (unicellular). Prokaryotic cells don't contain a nucleus.
