within a forest ecosystem, there is a large amount of diversity among members of a warbler species. of the following stages of meiosis illustrated for a typical cell, which contributes most to diversity among the warblers?

Answers

Crossing over occurs between homologous chromosomes, and is closely involved in genetic variation. The stage that most contributes to diversity is stage C, where you can see chromosomes after crossing-over.

----------------------------

There are different mechanisms involved in producing genetic variation among descendants. These are,

Crossing-over between homologous chromosomes (prophase 1), Random lining of homologous chromosomes (metaphase 1),Random fertilization

The Crossing-over events occur between two homologous chromosomes in the equatorial plane and make the daughter cells genetically different from the original one.

The Chiasma is the position where two homologous chromatids interchange genetic information, giving a place for new genetic material or information to be provided to descendants.

After crossing over, homologous chromosomes get separated again.

In the attached imaged there are four different stages of meiosis.

Stage C is the one that contributes the most to diversity.

We can see that crossing over has already occurred between homologous chromosomes, and they have already interchanged segments.

In the image you will see the difference between chromosomes that has gone through the crossing over mechanism, and chromosomes that has not. The difference in color represents segments interchange and variation.

Answers

The enzyme is a structure of proteins that can break amino acids in glucose

The enzyme dicer chops dsRNA molecules into small pieces of miRNA and siRNA. The correct option is B.

What is Dicer?

Dicer is an enzyme involved in RNA interference (RNAi), a cellular process that regulates gene expression.

Its primary role is to cleave double-stranded RNA (dsRNA) molecules into smaller fragments.

These fragments are typically around 21-25 nucleotides in length and serve as the building blocks for two types of small RNA molecules: microRNA (miRNA) and small interfering RNA (siRNA).

miRNAs are endogenous small RNA molecules that play a crucial role in post-transcriptional gene regulation. siRNAs are also small RNA molecules but are primarily involved in the defense against viral infections and the silencing of transposable elements.

Thus, the correct option is B.

Which is a point mutation and not a frameshift mutation?
mutagen

deletion
silent

Answers

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.
