In which of the following ways is DNA replication similar to transcription? X. New cells are created after both have happened. (Definitely not) ✓. Cytosine pairs with guanine in both. (True) X. Both take place in the cell cytoplasm. (They occur in the nucleus) ✓. Both create new DNA strands. (Technically no, but they create COPIES of DNA strands so this statements' wording is a bit confusing)

Yes.. I already had that site open & they didn't mention any of the available choices. I appreciate your research.

Transcription involves the creation of an RNA and more specifically an mRNA molecule using DNA as a template. RNA polymerase II binds to a region called the promoter region on DNA assisted by protein transcription factors. It unwinds and transcribes the DNA sequence in the 5 to 3 prime direction until it reaches the terminator region where it stops and releases the mRNA formed. It only reads and produces one strand. In DNA replication, DNA is unwound by helicase at several rather than one position to form "bubbles" and new complementary DNA strands are built on both parent strands. "Bubbles" are held open by special binding proteins. On the 3 to 5 prime strand DNA polymerase III builds continuously in the 5 to 3 prime direction. RNA primase initiates the process by adding an RNA sequence called the primer that is later replaced with a corresponding DNA one by DNA polymerase I. Opposite, the other new (lagging) strand is also built in the 5 to 3 prime direction but in discontinuous sections eventually joined together by ligase. It means that on this side several rather than one primers are formed in each bubble. Eventually all "bubbles" meet and fuse forming two new complete DNA molecules identical to the first. This process reads and produces two strands.

They are both similar in that they both copy the DNA strand. It is just that transcription is the complementary copy and replication is the exact copy. Also during both the DNA molecule unzips and a new strand of mRNA/DNA is formed

The answer is D!!!!!!!!!!!!!

Cytosine pairs with Guanine in both, but I'm not sure if that occurs during transcription… actually no it does when it creates the complementary strand
