Question

Which of the following is TRUE? Conjugation is a type of reproduction During fission, a conjugation tube forms between the donor cell and the recipient cell Conjugation increases the genetic diversity of bacteria Conjugation produces two genetically identical daughter cells Fission can occur as often as once every hour under ideal conditions

Answer 1

Answer:

THE FOLLOWING ARE TRUE;

1. CONJUGATION IS A TYPE OF REPRODUCTION

2. CONJUGATION INCREASES THE GENETIC DIVERSITY OF BACTERIA

3. FISSION CAN OCCUR AS OFTEN AS ONCE EVERY HOUR UNDER IDEAL CONDITIONS

Explanation:

Conjugation is a form of reproduction in bacterial cells in which cells transfer DNA by direct contact with the recipient cell. The process is mediated by plasmids which are non-chromosomal DNA molecules. Conjugation occurs in one direction because the donor cell is the only one with the conjugate plasmids. The donor cell sends out its sex pilus and attaches it to the recipient cell creating a conjugal bridge from which genetic materials can be transferred between the two cells. The bacterial chromosomes can also be transferred through conjugation. Conjugation allows for genetic diversity in bacterial cells because the transfer is unilateral and non-identical daughter cells are produced.

Fission of bacterial cells involves the splitting of the bacterial DNA that is replication, then the bacterial cell elongates and later split into two daughter cells with identical DNA. Fission in bacteria can take place every twenty minutes or often every hour under ideal and optimum conditions and a bacteria can produce a generation in just few hours.

During fission a conjugation tube is not formed, conjugation tube is formed during conjugation type of reproduction of bacterial cells and also conjugation does not produce genetically identical daughter cells because wide varieties of DNA or genes can be transferred resulting in bacteria with traits of several different species.
