DNA MAKES RNA MAKES PROTEIN

Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Which most directly affects the sequence of amino acids in a protein?
A
the DNA in the nucleus of the cell
B
the amino acids found in the cytoplasm
C
the type of cell in which the protein is made
D
the region of the cell in which the protein is made
Explanation: 

Detailed explanation-1: -So, the correct option is ‘The sequence of codons in mRNA’.

Detailed explanation-2: -So, the correct option is ‘The sequence of codons in mRNA’.

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: -A mutation in the gene encoding for a protein causes a change in the amino acid sequence can lead to changes in. No worries!

Detailed explanation-5: -The nucleotide sequence of a gene, through the medium of mRNA, is translated into the amino acid sequence of a protein by rules that are known as the genetic code. This code was deciphered in the early 1960s. The sequence of nucleotides in the mRNA molecule is read consecutively in groups of three.
