Question

DNA template strand 5' ________ 3' DNA nontemplate strand 3' ________ 5' Given the locally unwound double strand above, in which direction does the RNA polymerase move while transcribing DNA? a. 5' → 3' along the template DNA strand b. 3' → 5' along the nontemplate DNA strand c. 5' → 3' along the nontemplate DNA strand d. 5' → 3' along the double-stranded DNA e. 3' → 5' along the template DNA strand

Answer 1

3' → 5' along the template DNA strand. Replication may be defined as the process of production of daughter DNA from the parental DNA strand with the help of enzymes and chemicals. The two daughter DNA is produced from the single DNA strand. DNA dependent RNA polymerase is an important enzyme required for DNA replication. The DNA synthesis occurs in 5' to 3' direction whereas the enzyme RNA polymerase moves in the opposite direction. The RNA polymerase works in 3' to 5' direction along with the template strand.

Answer 2

3' → 5' along the template DNA strand.

Step-by-step explanation:

Replication may be defined as the process of production of daughter DNA from the parental DNA strand with the help of enzymes and chemicals. The two daughter DNA is produced from the single DNA strand.

DNA dependent RNA polymerase is an important enzyme required for DNA replication. The DNA synthesis occurs in 5' to 3' direction whereas the enzyme RNA polymerase moves in the opposite direction. The RNA polymerase works in 3' to 5' direction along with the template strand.

Thus, the correct answer is option (e).
