QUESTION 10

RNA polymerase initiates transcription without a DNA primer (DNA polymerase needs a primer for replication). So the statement is false.

• Francis Crick: Came up with the central dogma (J).
• Unambiguous: Each codon codes for only one amino acid (C).
• Promoter: Upstream of gene, recruits RNA polymerase (E).
• Terminator: Signals end of transcription (D).
• Coding strand: Not transcribed, has same sequence as mRNA (I - actual gene? Wait, correction: Coding strand's sequence (except T - U) matches mRNA, but the actual gene's coding sequence? Wait, re - matching:
• Coding strand: The DNA strand with the same sequence as the mRNA (except T/U), and the "actual gene" (coding sequence) is related, but maybe better: Coding strand - the strand that is not the template, and the exon is the coding sequence. Wait, let's re - match properly:
• Francis Crick: J (came up with central dogma).
• Unambiguous: C (one amino acid per codon).
• Promoter: E (upstream, recruits RNA polymerase).
• Terminator: D (ends transcription).
• Coding strand: The strand that has the same sequence as the mRNA (so the "actual gene" (coding sequence) is on it? Maybe I: actual gene? No, exon is coding sequence. Wait, exon is A (coding sequence of a gene). So:
• Coding strand: The strand that is not transcribed, and the template strand is G (DNA sequence transcribed).
• Template strand: G (DNA sequence transcribed into RNA).
• "gives the protein unique its structure": F (amino acid sequence determines protein structure).
• Frameshift mutation: H (caused by insertion/deletion of nucleotide).
• Intron: B (non - coding DNA in gene).
• Exon: A (coding sequence of gene).

Let's redo the correct matches:

1. Francis Crick - J (central dogma)
2. Unambiguous - C (one amino acid per codon)
3. Promoter - E (recruits RNA polymerase upstream)
4. Terminator - D (ends transcription)
5. Coding strand - I (actual gene, as it contains the coding sequence)
6. Template strand - G (DNA sequence transcribed)
7. gives the protein unique its structure - F (amino acid sequence)
8. frameshift mutation - H (insertion/deletion of nucleotide)
9. intron - B (non - coding DNA in gene)
10. exon - A (coding sequence of gene)

Answer:

False (the selected option is correct as RNA polymerase doesn't need a DNA primer for transcription; DNA polymerase needs a primer for DNA replication).
