Question

6. What is the relationship between an organism's DNA and protein specificity?

Answer 1

Answer:

The relationship between an organism's DNA and protein specificity is that DNA determines the amino acid sequence of each protein (option D).

Explanation:

Each organism's DNA molecule is formed by a specific sequence of nitrogenous bases that not only determine the amino acids that a synthesized protein will have, but also the order in which these amino acids will form the protein structure.

The steps in which this occurs can be summarized as follows:

1. The sequence of nitrogenous bases of a DNA strand  is transcribed into the mRNA, which will go into the cytoplasm.
2. The sequence of bases in the mRNA is organized into triplets of bases, called codons, each of which encodes a specific amino acid.
3. During translation, each codon will indicate the amino acid that will be coupled to a protein molecule in a specific order.

According to this, the DNA determines the amino acids sequence that will be in a specific protein molecule.
