Question

Select the correct statement.
(A) mRNA provides the template for synthesis of proteins.
(B) snRNA brings amino acids and reads the genetic code.
(C) RNA polymerase binds to promoter and initiates transcription.
(D) A segment of DNA coding for polypeptide is called as an intron.

• A. (A) and (C)
• B. (A) and (B)
• C. (A), (B) and (C)
• D. (B) and (C)
• E. (A), (B) and (D)

Answer 1

The correct option is A (A) and (C)

During translation, messenger RNA (mRNA) provides the template to synthesize a chain of amino acids that form a protein. Transfer RNA (tRNA) reads the genetic code and brings amino acid specified by the codon. RNA polymerase binds to DNA sequence called the promoter and initiates transcription. A segment of DNA coding for the polypeptide is called as the exon. Non-coding DNA segment is called the intron. Thus, the correct answer is option A.
