Consider the process that a cell uses to replicate its double strand $DNA$ to make copies for daughter cells. Which statement describes the $DNA$ in daughter cells?
The double helix in one daughter cell consists of two strands that were originally in the parent cell, while the double helix in the other daughter cell consists of two newly made strands.
The two strands of the double helices in both daughter cells consist of segments of new and parental $DNA.$
The double helices in each daughter cell consists of one parental strand and one newly made strand.
None of the above.

Now a days which of the following are known as "magic circles"
A complex of ribosomes attached to a singlestrand of $RNA$ is known as
Assertion : The uptake of $DNA$ during transformation is an active, energy requiring process.
Reason : Transformation occurs in only those bacteria, which possess the enzymatic machinery involved in the active uptake and recombination
The salivary gland chromosomes in the dipteran larvae, are useful in gene mapping because
