Multiple choice

Match the proteins in column – I with their functions in column – II.

 
Column – I Column – II
P. Cyclic AMP receptor 1. Regulates the expression of a large number of developmentally-regulated genes
Q. CD59 antigen 2. Allows the sperm to pass through the envelope and fuse with ova
R. Egg lysin 3. Inhibits formation of membrane attack complex
S. Exosortase 4. Recognises and cleaves the carboxyl-terminal sorting signal PEP-CTERM

  1. P - 1; Q - 2; R - 3; S - 4

  2. P - 1; Q - 3; R - 2; S - 4

  3. P - 2; Q - 4; R - 3; S - 1

  4. P - 2; Q - 3; R - 4; S - 1

  5. P - 4; Q - 3; R - 2; S - 1

B Correct answer
Explanation

This option is correct. All proteins are correctly matched with their functions. Cyclic AMP receptor regulates the expression of a large number of developmentally-regulated genes. CD59 antigen inhibits formation of membrane attack complex. Egg lysin allows the sperm to pass through the envelope and fuse with ova. Exosortase recognises and cleaves the carboxyl-terminal sorting signal PEP-CTERM.
