Final answer:
DNA provides the code for protein synthesis, with the information transcribed onto mRNA, which is then translated by ribosomes into a specific sequence of amino acids to form a protein. Option B is correct.
Step-by-step explanation:
What does DNA provide the code for? DNA provides the code for protein synthesis. Specifically, DNA is the source of information for the synthesis of all cellular body proteins. The instructions inscribed on DNA are transcribed onto messenger RNA (mRNA).
This mRNA then interacts with the ribosome, which reads the genetic information and strings amino acids together to form a protein. This process involves the DNA specifying the sequence of RNA, which is then read in sets of three bases known as codons. Each codon in the mRNA sequence codes for a single amino acid in the protein sequence, following the rules of the genetic code.
B. DNA provides the code for protein synthesis. It contains the instructions for the synthesis of messenger RNA (mRNA), which serves as the template for the production of proteins. The mRNA is read by ribosomes during the process of translation, where amino acids are added in the correct sequence to form a protein according to the information encoded in DNA.
