What do you think if it is how many "different" types?(02-10-2017, 11:33 PM)CHANDA7 Wrote: A polypeptide has 4 cysteine residues. How many intra-chain disulphide bond could be made with these 4 residues? (Memory based)
Disulfide needs a pair of residues, so it should be 2 bonds..
RE: GATE BT-2017 Answer Key | Solutions Discussion - SunilNagpal - 02-11-2017
If it is about number of different ways those 2 bonds can form between the 4 residues, then it should be 3 ways (i think so...not sure though...) 6 is number of combinations of residue pairs possible, while there is one way of bonding per 2 pairs of residues....so it should be 3 ways of bonding...
a-------a---------a---------a
way1: a1-a2 a3-a4
way2: a1-a3 a2-a4
way 3: a2-a3 a1-a4
This exhausts all possible combinations...
3 ways it should be...

3; way right ans.
RE: GATE BT-2017 Answer Key | Solutions Discussion - SãñGáM Mìshra - 02-11-2017
And in q,s of cell cycle .... Main theme is ... The completion of genome duplication and before mitosis begin....it must be duplicated in end of G2 phase . so ans. Is s and G2.

Thanks for the input but I couldn't understand the theme suggested by you...could you please elaborate? And was the question about DNA content or about the ploidy?

Hello sangam,
[/quote]
Nither dna content nor ploidy . only .. End of which phases of cell cycle ( mitosis ) the completion of genome duplication takes place..

In that case S and G2 are indeed the two phases..
