The strand of the opened DNA is easily replicated, but the strand must be replicated in pieces because of its orientation. a. bottom; top
b. lagging; leading
c. leading; lagging
d. top; bottom

c. leading; lagging

Explanation:

This question s describing the process of DNA replication, which is the process by which DNA forms an identical copy of itself. The process of DNA replication is carried out majorly by an enzyme called DNA polymerase. After which the double stranded DNA has been unwound by DNA helicase, two single strands results.

One of these strands runs in the 3'-5' direction called LEADING STRAND while the other runs in the 5'-3' direction called LAGGING STRAND. However, because replication by DNA polymerase proceeds in the 5'-3' direction, the LEADING strand of the opened DNA is easily replicated, but the LAGGING strand must be replicated in pieces called OKAZAKI FRAGMENTS because of its orientation.

it's     c       this is a cell (b) with a nucleus (c) containing dna (a). the dna is organized into chromosomes (d). a section of the chromosome that codes for a trait is called a gene (e).

the "dirty dozen" chemicals banned in an international treaty are formally known as persistent organic pollutants, or pops. the united nations environment program provided this background on what they are and what they can do to humans and wildlife.
