Answer;
B. Proteins.
Explanation;
-Information that is stored in DNA molecules is used to manufacture proteins through the process of transcription and translation.
-During transcription, DNA molecules are used to generate mRNA (messenger RNA), which then undergoes translation in the cytoplasm to generate proteins. These proteins include enzymes that control or regulate and catalyze different biological reactions in the body.
- Additionally, one of the characteristic of protein is being protein in nature which means like proteins they are produced through translation in the ribosomes.
