What can you conclude about DNA replication from this diagram?
A. Both original strand dare replicated in the same direction.
B. The two original strands are replicated in opposite directions.
C. Only one complementary strand is replicated.
D. Each original strand is broken apart and nucleotides are reused.

Hi there!

From this diagram, we can see that the DNA was unwinded and a DNA polymerase on the two strands. From this image, we can see that for the strand on the left, the completed strand is going top down, while for the one on the left it is going bottom up. Thus, your answer is the two original strands are replicated in opposite directions.

Explanation on why this happens: The DNA strands are also facing in opposite directions: (from top down) one goes from the 3' -> 5', and the other goes from 5' to 3'. When they are replicated, the replication happens from 5' to 3'. This means that the DNA are replicated in opposite directions as the strands themselves are facing in different directions.

Hope this helps!

answer: that would be cheating

explanation:

the answer would be 2, if crossing over doesn’t occur 2 out of 4 of the daughter cells will have that allele.

hope this : )
