Which of the following statements correctly describes the difference between the leading and the lagging strands of DNA during D

NA replication? A The leading strand is synthesized in the same direction as the movement of the replication fork, and the lagging strand is synthesized in the opposite direction. B The leading strand is synthesized by adding nucleotides to the 3' end of the growing strand, and the lagging strand is synthesized by adding nucleotides to the 5' end. C The lagging strand is synthesized continuously, whereas the leading strand is synthesized in short fragments that are ultimately stitched together. D The leading strand is synthesized at twice the rate of the lagging strand.

The answer is; A & C

The lagging strand is replicated in fragments called Okazaki fragments, each initiated by a primer. The fragments are later joined into one strand by DNA ligase. Replication occurs by adding nucleotides to the 3’ end of a preceding nucleotide. Because the lagging strand is antiparallel to the leading strand, the replication of the lagging strand is in the opposite direction as the replication fork direction. This is why the lagging strand is replicated in fragments because replication is being carried out by a single DNA polymerase (moving in the direction of the replication fork) per replication fork.

A recombinant plasmid created during a recombinant DNA experiment:

Answer:

B.carries and allows expression of a foreign gene of interest.

Explanation:

Plasmids are the low molecular weight extrachromosomal DNA molecules that are able to replicate themselves independent of chromosomal DNA due to the presence of "ori" (origin of replication).

Plasmids serve as vectors in recombinant DNA technology as some of their genes can be replaced with the gene of interest to create recombinant plasmids.

The restriction enzymes that create the sticky ends and DNA ligases facilitate the insertion of the foreign gene into the plasmids.

The host cells are made competent to take up the recombinant plasmids. Once inside the host cell, the recombinant plasmids replicate themselves and express the gene of interest that they carry.

vitfil [10]
Hello LonelyPerson, to answer your question.
The Galápagos were officially annexed by Ecuador in February 12 1832 and were named "Archipelago del Ecuador.". It is still today officially a province of Ecuador. Ecuador claimed the <span>Galápagos Islands</span> just three years before their most famous visitor, Charles Darwin, dropped anchor on the Beagle and stepped ashore and into history.

Why do X-linked traits appear more often in males
Tpy6a [65]
X - linked traits appear more often in males because males only have one x chromosome. One copy of an x - linked trait is all that a male would need to possess that trait. Females have two x chromosomes, so they would require 2 copies of the x - linked trait in order to possess it.
