I choose option 1
(02-16-2017, 01:48 AM)I guess the answer is "C".  Not to forget that its a DNA feagment and not a circular plasmid so 5 Kb frgmanet is not possible. I might be wrong please correct me if I am. CHANDA7 Wrote: [ -> ]

"A"

Sunil sir, what is your opinion on this question ?
I guess the confusion is at the word "free protein"... assuming that by free protein one refers to precipitated protein, then option C is correct. Otherwise, as a classical case, option A is right.

Moreover, are they expecting an assumption of progressive addition of ammonium sulphate? (that's another point to ponder)...

Q: A bacteria has genome of size 6 million bp. If DNA synthesis rate is 1000 bp/ second. How long does it take (in minutes) for replication of genome?

Ans: Size= 6000000bp
Speed= 1000bp/second
Time needed= 6000000/1000 seconds = 6000 seconds = 100 mins


Here the assumption is that there is only one replication fork.

Keep a note in future that, each replication fork works independently at the same pace. Therefore, had there been 2 replication forks, time taken would have been 100/2 mins I.e 50mins . 33.33 mins for 3 forks and 25mins for 4 forks and so on..
