23. How many total chromosomes are in a germ cell in the testis of this organism that is in Metaphase of Meiosis II?

Answers

There are 46 chromosomes in each cell at metaphase II in meiosis in humans. Normal human body cells each have 46 chromosomes. Prior to meiosis, the DNA replicates and each cell gets 92 chromosomes.

Final answer:

A germ cell in the testis in Metaphase II of Meiosis has 23 chromosomes.

Explanation:

In Metaphase II of Meiosis, the chromosomes line up at the equator of the cell and are ready to be separated into two daughter cells. Each daughter cell will receive half the number of chromosomes as the parent cell. In humans, the diploid number of chromosomes in a somatic cell is 46, while the haploid number of chromosomes in a germ cell is 23.

Therefore, in Metaphase II of Meiosis, a germ cell in the testis would have 23 chromosomes.

Describe how an enzyme’s structure affects its function

Answers

4

adenine,thyamine,cytocine,guanine

Final answer:

An enzyme's structure determines its function, stability, and activity.

Explanation:

An enzyme's structure directly affects its function. Enzymes are proteins made up of chains of amino acids. The specific sequence and arrangement of these amino acids determine the three-dimensional shape of the enzyme, which in turn determines its function. For example, the active site of an enzyme is a small pocket or crevice that allows the enzyme to bind to its substrate and carry out a specific chemical reaction.

The structural characteristics of an enzyme also affect its stability and activity. Changes in temperature, pH, or salinity can alter the shape of the enzyme, rendering it inactive or less efficient. Additionally, certain environmental factors may denature the enzyme, causing it to lose its shape and functionality permanently.

The substitution, addition, or removal of a single nucleotide in DNA is called a(n) ____________ mutation.A)interstitial
B)normal
C)point
D)reference

Answers

I think the correct answer from the choices listed above is option C. The substitution, addition, or removal of a single nucleotide in DNA is called a point mutation. It is a type of mutation that affects only one or very few nucleotides in a gene sequence.

Answer : The correct answer for the blank is -  C) point mutation.

Mutation can be described as the permanent change in the sequence of genetic material (that is DNA) of living organisms.

Point mutation corresponds to change in one nucleotide sequence of DNA.

There can be primarily three types of point mutation that is deletion (one nucleotide is deleted from the sequence), addition (a nucleotide is added), and substitution (a nucleotide is substituted by another nucleotide).

Thus, option C) is the right answer.
