How many DNA strands exist at the completion of semi conservative replication?

Answer 1

Ruby Armstrong

4 strands

Here is the original strand.

GTAC CATG

when you replicate the DNA, you get the following:

GTAC and gtac catg CATG

Four distinct strands: two handmade and two original.

At the completion of semi-conservative DNA replication, there are two DNA strands. Each original DNA molecule (parental strand) serves as a template for the synthesis of a new DNA strand (daughter strand), resulting in two identical DNA molecules, each consisting of one original strand and one newly synthesized strand. This process ensures the preservation of the genetic information during cell division. Therefore, at the end of semi-conservative replication, there are two double-stranded DNA molecules, each composed of one parental strand and one newly synthesized daughter strand.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
