Answer:
Mitosis produces new cells, and replaces cells that are old, lost or damaged. In mitosis a cell divides to form two identical daughter cells.

The spindle fibers will move the chromosomes until they are lined up at the spindle equator. Metaphase: During metaphase, each of the 46 chromosomes line up along the center of the cell at the metaphase plate. Anaphase: During anaphase, the centromere splits, allowing the sister chromatids to separate
Answer:
Deletion of a DNA base from a gene affects an organism by changing the sequence of amino acids in a protein.
Explanation:
A DNA fragment forms a gene, with a specific sequence of nitrogenous bases, which determines the synthesis of a specific protein. When a deletion of a base occurs in such a gene, it affects:
- Transcription of the mRNA, which will have the sequence of altered bases.
- During translation, the mRNA codons will encode at least one different amino acid.
- The structure of the synthesized protein, which will be altered by changes in its amino acid sequence.
In summary, the <u>deletion of a base in the DNA</u><u> will affect the </u><u>protein</u><u> to be synthesized by </u><u>changing the amino acid sequence</u><u> of its structure</u>.
The other options are not possible, because the deletion of a base in the DNA of a gene
<em> Does not influence the number of chromosomes that the gametes will have.
</em>
<em> It does not produce long chains in the chromosomes.
</em>
<em> It does not affect the ribose structure of the nucleic acids.</em>
