For proving the semi conservative mode of replication of $DNA$ , $E-coli$, were first grown in the medium containing ?
$^{14}NH_3$
$(NH_4)_2 SO_4$
$^{15}NH_4CI$
$^{14}NH_4CI$
Smallest structure having the power of replicating itself is
It has not escaped our notice that the specific pairing we have postulated immediately suggests a possible copying mechanism for genetic material. This is written by
Choose the correct statement about the direction of $DNA$ strand
During $DNA$ replication, why is it that the entire molecule does not open in one go ? Explain replication fork. What are the two functions that the monomers $(dNTPs)$ play ?
The experimental proof for. semiconservative replication of $DNA$ was first shown in a
