Help on Semiconservative replication

I understand that each strand serves as a template during DNA replication. Therefore the daughter DNA will have 1 parent strand and 1 newly synthesized strand.

I remember encountering a problem from one of the full length kaplan tests and it says something along this line ... "If 16P is incorporated into a double stranded DNA, after 3 replication, how many of the strands contain the 16P?"
I remember I got that question wrong, and since my kaplan subscription is up, I could not look up my old tests...can someone help me out on this problem?

thanks in advance.

i've never heard of 16P. what's 16P 😕
anyway if i call it poop, 1 replication will make 2 poops, thus 3 replication will make 4 poops.

with each round of replication, the original double stranded DNA gets halved. so after 3 replications, you have (1/2)^3=1/8 or 0.125% of the original strands contain the 16Phosphorus. hope this helps! dont you just love genetics 😍

can't 16P itself be replicated? so it would multiply instead of divided?

Is the answer 1/16?

No, the question is saying that 16P was incorporated into the original double stranded DNA, so how many original strands are you going to have after 3 rounds of semi conservative replication, because only the original strands of DNA will contain the 16P and not any of the newly synthesized duaghter strands.
the answer is 1/8

Ok...now I read this title really quick...and I thought it said "help i'm a semi-conservative republican!" I was going to say... GOOD FOR YOU! 🙂
