uses a single strand of a DNA molecule as a template for the creation of a new double strand.
is carried out the DNA polymerase.
Homework Answers
Answer: DNA replication is a biological process that involves formation of two identical copies of DNA from one parental DNA strand. During replication, two strands of the DNA separates and each strand acts as template for the creation of new double strand. DNA replication is carried out by an enzyme called as DNA polymerase that add nucleotides to the 3'end of the growing DNA strand. Chromosomes are composed of DNA. Duplication of DNA leads to duplication of chromosomes. Hence, All the choices are correct.

Why does a new DNA strand elongate only in the 5' to 3' direction during DNA...
Why does a new DNA strand elongate only in the 5' to 3' direction during DNA replication? The polarity of the DNA molecule prevents addition of nucleotides at the 3' en Replication must progress toward the replication fork. DNA polymerase can add nucleotides only to the free 3' end. DNA polymerase begins adding nucleotides at the 5' end of the template,

Formation of a replication fork results in: A. continuous synthesis of DNA on the lagging strand. B. supercoiling in the parental DNA ahead of the fork. C. of new 3' -OH regions on the template DNA. D. binding of SSB protein on the double-stranded parental DNA. E. All of the above occur when the replication fork is formed.
