Answer #1

Answer :- Correct answer are given in capital letters-
1. To initiate transcription, RNA polymerase must recognize the PROMOTOR sequencence on DNA.

2. Ribosomal 30S subunit binds to mRNA by recognizing INITIATION FACTOR 3 (IF3) sequence upstream of the start codon.

3. A special initiator tRNA called P-SITE binds to the 30 S site of the 70S ribosome for base pairing with the ATG start codon.

4. If RNA polymerase transcribes a long mRNA encoding more than one polypeptide, it is called a (an) POLYSOME RNA.

5. Some genes are expressed constantly at a fixed rate. These gene are CONSTITUTE genes.
