Question

Consider the following statements.
I. rRNA provides the template for synthesis of proteins.
II. tRNA brings amino acids and reads the genetic code.
III. RNA polymerase binds to promoter and initiates transcription.
IV. A segment of DNA coding for polypeptide is called intron.
Which of the statements given above are correct?

• A. I and III
• B. I and II
• C. I, II and III
• D. II and III

Answer 1

The correct option is D II and III

The segment of DNA coding for a polypeptide is called exon and the noncoding segment of DNA is called an intron. mRNA and not rRNA, provides the template for synthesis of proteins.
