Question

After transcription the DNA molecule,

• A. Moves to a ribosome
• B. Replicates itself
• C. Disintegrates its components
• D. Reassociates to form its original structure

Answer 1

Answer: (D)

Reassociates to form its original structure

Linear sequences of deoxyribonucleotides in DNA are transcribed into ribonucleic acid (RNA) molecules with complementary ribonucleotide sequences. It occurs in nucleus and involves separation of two DNA strands and synthesis of an RNA molecule in the 5' to 3' direction by RNA polymerase. After completion of transcription, the two strands base pairs together to reassume the double stranded configuration. Ribosomes are the large complex of rRNA and proteins and serve as site for protein synthesis using mRNA template. DNA does not move from nucleus to cytoplasm for ribosome. DNA replication and transcription are independent processes. Correct option is D.
