This is mainly because in order to the tumour suppressor gene to be completely expressed or to no longer be effective in repressing cellular production, both versions, alleles of the gene must be mutated. This is the only way that the rumour suppressor gene to be inactive in its role and behave as a dominant gene.
Answer& explanation:
The mechanism of action of chloramphenicol can be explained as follows:
Chloramphenicol binds to the 50S subunit of the ribosome, inhibiting the protein synthesis of the bacteria, thus having bacteriostatic action (inhibiting the growth of bacteria, preventing their proliferation).
In addition, chloramphenicol can be bactericidal (destroys bacteria) when in high concentrations, or when used against highly sensitive microorganisms, such as <em>Haemophilus influenzae</em> and <em>Streptococcus pneumoniae</em>. The mechanism of action for these bacteria, however, is not yet elucidated.
E. One cell contains more mitochondria than the other.
In animals and plants, there are two pairs of chromosomes - one set from a male and the other set from a female. But occasionally, the original fertilized cell doesn't quite divide correctly and more than two sets arises. The fertilized cell continues to divide with the result that all the cells have the extra set of chromosomes. This happens much oftener in plants and the plant will be sterile and can't form seeds.
