Question

The part of the bacterial chromosome that is homologous with genome fragment which is transferred from the recipient during the formation of merozygote is called
A. Eugenic
B. Exogenote
C. Endogenote
D. Dysgenic

Answer 1

The bacterial conjugation is described as the transferring of genetic material between bacterial cells. This can be done by cell-to-cell contact or by forming a bridge-like connection between two bacterial cells. The donor bacterium possesses a DNA sequence which is known as fertility factor or F-factor. The process of conjugation is used to share genetic material.

Complete answer:
Merozygote is described as a stage when a bacterial cell is partially diploid temporarily. This can result from the transfer of DNA in the conjugation process. The process of conjugation involves the transferring of genetic material between bacterial cells.

When the exchange of genetic material is carried out as part of the bacterial cells recombination process, the merozygote formation occurs. At this stage, the cell contains two copies of the same part of the bacterial chromosome.

This similar or homologous part of the bacterial chromosome received from the recipient cells is known as endogenous. On the other side, the remaining part of the bacterial chromosome that is not similar is called exogenate.

Hence, the correct answer is option (C).

Additional information:
The homologous chromosomes are described as the two pieces of DNA that carry the same genes. They are present in the diploid organism. Each parent provides the same 23 chromosomes that encode the same genes.

Note: The conjugation is the process in which one bacterium transfers its genetic material to another bacterium. This can be done by direct contact. During this process, one bacterium acts as a donor, whereas the other bacterium acts as the recipient. Moreover, a similar part of the chromosome is known as endogenote, whereas the chromosomes dissimilar part is known as exogenote.
