Answer: B. conjugation

Conjugation is the reproductive stage of bacterial cells wherein a bridge-like structure is form between two bacterial cells that allows the transfer or the transport of genetic material from one cell to the other cell in the form of a plasmid.

A gene mutation is a change in the sequence of nucleotides that occurs during cell replication (mitosis and meiosis)within a sin
Shalnov [3]

True

Changes in the transcription of mRNA or the translation of a polypeptide are not considered to be mutations because they are not permanent changes to the cell.

Explanation:

The half-life of mRNA and proteins is short. mRNA has an average of 10 hours of life span while proteins have an average of  several days. Therefore mutation in these biomolecules will only persist as long as this mutated mRNA of protein exists. After its life-span, the molecule is degraded and replaced by a non-mutated mRNA or proteins. This is because the piece of DNA that codes for the mRNA and subsequent protein is not mutated. A mutation on DNA is the permanent kind of mutations because DNA is a highly stable molecule that stores information about the cell.

A scientist is comparing cancerous cells with noncancerous cells.
Simora [160]

The scientist should notice that the cancer cells have a <u>higher</u> rate of cell division and  have a <u>lower</u> response to inhibiting factors. Cell groups that are cancerous should  have a <u>lower</u> percent of cells in interphase than noncancerous cells.

Explanation:

The general characteristics of cancerous cells are defined by the ‘hallmarks of cancer’ like ‘enable replicative immortality, activate invasion and metastasis, resist cell death, evade growth suppressors’ etc. All these facts prove that they grow and divide at a higher rate and undergo uncontrollable mitotic cell division leading to proliferative invasion.

The cancerous cells also show low or no response to inhibiting factors like growth suppressors like p53, cyclins and other anti-tumor drugs.

The number of cancer cells in interphase is lower than noncancerous cells because interphase is a phase of cell growth, development and differentiation. Cancer cells undergo uncontrollable mitosis and more time is spent after the interphase to facilitate rapid cell division rather than growth or development.
