DNA MAKES RNA MAKES PROTEIN

Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Which factor most affects the order of amino acids in a protein?
A
the DNA located in the nucleus of the cell
B
the cell in which the protein is located
C
the amount of ATP available for a cell’s use
D
the area in the cell where proteins are produced
Explanation: 

Detailed explanation-1: -The sequence of amino acids in a protein and protein function are determined by the genetic code.

Detailed explanation-2: -The order of amino acids in a protein affects its structure and function. This order is encoded by the DNA in the corresponding gene. Some changes to the DNA sequence can change the encoded amino acid and therefore the final protein.

Detailed explanation-3: -Like words in a sentence, the DNA sequence of a gene determines the amino acid sequence for the protein it encodes. In the protein-coding region of a gene, the DNA sequence is interpreted in groups of three nucleotide bases, called codons. Each codon specifies a single amino acid in a protein.

Detailed explanation-4: -The actual order of the amino acids in the protein is called its primary structure and is determined by DNA. The order of deoxyribonucleotide bases in a gene determines the amino acid sequence of a particular protein.
