Biology
1 answer:
ludmilkaskok [199]3 years ago
5 0

Answer:

Vaccines introduce an attenuated form of the virus or bacteria into the body.

Explanation:

Vaccines introduce an attenuated form of the virus or bacteria into the body, meaning the virulence of the virus or bacteria has been negated. Introduction of this attenuated form enables the immune cells to easily eliminate the pathogen even without getting diseased and later have memory (in memory B and T cells) so that in case of a real infection, it is easily eradicated.

What is the role of the dna ligase in dna replication
marissa [1.9K]
DNA ligase is an enzyme that repairs irregularities or breaks in the backbone of double-stranded DNA molecules. It has important role in the process of DNA replication and DNA repair. It has three general functions: It seals repairs in the DNA, it seals recombination fragments, and it connects Okazaki fragments (small DNA fragments formed during the replication of double-stranded DNA). DNA ligase functions by forming a bond between the end of a “donor” nucleotide and the end of an “acceptor” nucleotide.
