3 question is suggested by B. K. Vijay Jayraman and 1 question is suggested by Shafkat Ali Khan.

 

 

Answer

 

1. (A) Promoter Sequence

        No gene is working without Promoter. It is very essential structural part of the gene which interact with RNA Polymerase

 

2. (D) homing endonuclease

        Homing Endonuclease is intronic sequence

 

3. (C) Ethylene

        Ethylene is gas. Its formula is CH2=CH2 and this is the smallest known molecule that can act as Hormone in plants.

 

4. (B) Protein splicing Proteins

        Inteins are Protein splicing Proteins which is translated with host protein. This precursor protein undergoes an autocatalytic protein splicing reaction resulting in two products: the host protein and the intein.

 

5. (B) P-Banding

        G-Banding use "Giemsa" to get bands in chromosome, Q-Banding use "Quinicrine mustard dihydrochloride" and The reverse of G-Bands is obtained in R-Banding but there is no P-Banding.

 

6. (D) none of the above

        There is no pH at which any amino acid is in non-ionised form

 

7. (B) RFLP

        in RFLP polymorphism of DNA is obtained by various fragment of DNA which is generated by Restriction Endonuclease and no PCR is used.

 

8. (B) Chromosome 1

        Chromosome names are given according to their length or size so Chromosome 1 is biggest and Chromosome 21 is smallest (which is wrongly placed) it should be in the position of 22. Remember Chromosome 21 is smaller then Chromosome 22.

 

9. (D) Bhubaneswar

        "Institute of Life Sciences" is situated in Bhubaneswar.

 

10. (B) RNA

        HIV is Retrovirus and its genome is RNA
