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>
The Cell to Mentee
A cell is the basic unit of life of a human. The body cell contains cytoplasm in which organelles are present . There is a nucleus found in eukaryotic cell. It contains the genetic material in the form of DNA with proteins and chromosomes. Inside there is nuclear membrane. Outside the nucleus, there are many other organelles like mitochondria, ribosomes, golgi apparatus, endoplasmic reticulum, and many more.
Answer:
