Replication of $DNA$ is in
$3’ → 5’$ direction
$2’ → 5’$ direction
Both $3’ → 5’$ and $5’ → 3’$ direction
None of these
(c)Replication of $DNA$ is in unidirectional and Bidirectional.
Smallest structure having the power of replicating itself is
What is the cause of discontinuous synthesis of $DNA$ on one of the parental strands of $DNA$ ? What happens to these short stretches of synthesised $DNA$ ?
A $DNA$ molecule in which both strands have radioactive thymidine is allowed to duplicate in an environment containing non-radioactive thymidine. What will be the correct number of $DNA$ molecules that contain some radioactive thymidine after three duplications
For proving the semi conservative mode of replication of $DNA$ , $E-coli$, were first grown in the medium containing ?
Escherichia coli fully labelled with $15 \mathrm{~N}$ is allowed to grow in $14 \mathrm{~N}$ medium. The two strands of $DNA$ molecule of the first generation bacteria have
Confusing about what to choose? Our team will schedule a demo shortly.
