Why is the new DNA strand complementary to the 3′ to 5′ strands assembled in short segments?

Question: Why is the new DNA strand complementary to the 3′ to 5′ strands assembled in short segments? -DNA polymerase can assemble DNA only in the 5′ to 3′ direction -it is more efficient than assembling complete new strands -the replication forks block the formation of longer strands -only short DNA sequences can extend off … Read more

How does RNA polymerase know where to start transcribing a gene into mRNA?

Question: How does RNA polymerase know where to start transcribing a gene into mRNA? -Transfer RNA acts to translate the message to RNA polymerase. -The ribosome directs it to the correct portion of the DNA molecule. -RNA polymerase starts when the enzyme attaches to a specific nucleotide sequence called a promoter at the beginning of … Read more

Which statement about DNA replication is FALSE?

Question: Which statement about DNA replication is FALSE? Which statement about DNA replication is FALSE? Because the two strands of parental DNA run in opposite directions, the new strands must be made in different ways. The two strands of parental DNA are separated during DNA replication. The lagging strand is made of a series of … Read more
