Question

A normal lighter dna molecule is continuosly replicate in n15 medium than what is the % of lighter dna in 4th generation

Answer 1

The correct answer is 12.5%.

Explanation:

• The DNA replication is semi conservative i.e. Not fully conservative.
• DNA replication ends up being a separation of the two mother DNA strands and the formation of the new DNA strands with each older one.
• Thus with the 1st generation replication, both the DNAs will be hybrid between the N14 and N15 species.
• The 2nd generation will have 50% of N14-N15 hybrid and 50%N15 DNA.
• The third generation will have 25% hybrid and 75% N15 DNA.
• The fourth-generation will have 12.5% of the hybrid. Thus, the lighter DNA will be 12.5%.

Answer 2

Answer:

0 %

Explanation:

Because is dna is continuously replicating in N15 (heavy medium) it is not transferred to N15 medium ( lighter medium) so it will have only heavy dna
