which statement summarizes the relationship between dna, proteins, and amino acids?\no the dna molecule is a protein formed by amino acids that are linked together by peptide bonds.\no the type of protein that composes dna codes for the twenty different amino acids.\no the sequence of amino acids in dna determines the type of protein formed during protein synthesis.\no the sequence of nucleotides in dna codes for specific amino acids which bond to form proteins.
Answer
Brief Explanations:
DNA is made of nucleotides. The sequence of these nucleotides (in the form of codons) codes for specific amino acids. Amino acids bond (via peptide bonds) to form proteins. Let’s analyze each option:
- The DNA molecule is not a protein. Proteins are made of amino acids, DNA is made of nucleotides. So the option “The DNA molecule is a protein formed by amino acids that are linked together by peptide bonds” is wrong.
- DNA does not have amino acids. Amino acids are part of proteins. So the option “The sequence of amino acids in DNA determines the type of protein formed during protein synthesis” is wrong.
- DNA codes for amino acids (not the other way around). Proteins are made of amino acids. So the option “The type of protein that composes DNA codes for the twenty different amino acids” is wrong.
- The sequence of nucleotides in DNA (arranged as triplet codons) codes for specific amino acids. These amino acids then bond to form proteins. This is in line with the central dogma of molecular biology (DNA → RNA → protein, where the nucleotide sequence in DNA is transcribed to RNA and then translated to a sequence of amino acids to form a protein).
Answer:
The sequence of nucleotides in DNA codes for specific amino acids which bond to form proteins.
