Question 2
mRNA is A. a double-stranded molecule. B. found only in eukaryotic cells. C. found exclusively in the nucleus. D. formed during transcription of DNA.
Worked Solution & Example Answer:mRNA is A. a double-stranded molecule - VCE - SSCE Biology - Question 2 - 2009 - Paper 1
Step 1
D. formed during transcription of DNA.
Answer
mRNA (messenger RNA) is a single-stranded molecule that plays a crucial role in the process of gene expression. During transcription, the DNA sequence of a gene is transcribed to produce mRNA in the nucleus of eukaryotic cells. This mRNA then travels to the cytoplasm where it serves as a template for protein synthesis during translation.
Thus, the correct statement about mRNA is that it is formed during the transcription of DNA.
