Question

At the end of this process in this cell, each DNA strand is...

Completely built new with a different code

Is one half the original DNA and one half new DNA with the same code as the original strand preserved

Is one half the original DNA and one half new DNA with a different code

Answer 1

Is one half the original DNA and one half new DNA with the same code as the original strand preserved

Step-by-step explanation:

I am assuming the process is DNA replication.

The process of DNA replication:

step 1- the DNA double helix unwinds using an enzyme called dna helicase. Proteins hold the strands apart from each other forming a Y shape called the replication fork.

step 2- At the replication fork, enzymes called DNA polymerase move along each of the DNA strands adding complementary bases to the nitrogen bases using base pairing rules.

step 3- DNA polymerases add nucleotides to a growing double helix until all the DNA is copied

result- 2 new DNA molecules, each made of one original strand and one copied strand
