Answer (1)
1. B. DNA serves as a template for RNA production (Transcription): This is the first step. The DNA molecule unwinds, and an enzyme called RNA polymerase creates a complementary messenger RNA (mRNA) molecule[__LINK_ICON]. 1. E. RNA moves from the nucleus to the cytoplasm: After transcription, the newly synthesized mRNA molecule leaves the nucleus and enters the cytoplasm[__LINK_ICON]. 2. A. Messenger RNA attaches to a ribosome: In the cytoplasm, the mRNA molecule binds to a ribosome, the cellular machinery responsible for protein synthesis[__LINK_ICON]. 1. C. Transfer RNA bonds to a specific codon: The ribosome reads the mRNA sequence in three-base units called codons. Transfer RNA (tRNA) molecules, each carrying a specific amino acid, recognize and bind to their corresponding codons on the mRNA[__LINK_ICON]. 2. D. Amino acids are bonded together (Translation): As tRNA molecules bring their amino acids to the ribosome, peptide bonds form between the amino acids, creating a growing polypeptide chain. This process continues until a stop codon is reached, signaling the end of the protein[__LINK_ICON].
