Question

Which one of the following pair is incorrect ?
(a) Plasmid - small piece of extrachromosomal
DNA in bacteria
(b) Interferon - an enzyme that interferes with
DNA replication
(c) Cosmid - A vector for carrying large DNA
fragments into host cells
(d) Myeloma - antibody producing tumour
cells.

Answer 1

Answer:

option b) is wrong because interferon are the group of proteins which produced antibody and also causes the cell lysis by creating hole on the antigen.

Answer 2

Incorrect statement:

• Option “B” is correct i.e. Interferon is an enzyme that helps in DNA replication.

• Interferon (IFNs) are proteins made and discharged by virally infected host cells in reaction to the incidence of pathogens, such as viruses, bacteria, parasites, or tumor cells to defend the adjacent cells from the infection by interfering DNA replication of the virus in the host cell. So, the correct option is option B.
