Answer:
Humans contain 46 chromosome or 23 pairs of chromosomes. Among them 22 pairs are autosomes and one pair contains the sex chromosome. Humans female are XX and human males are XY.
The X chromosome determines the sex of an individual and females one X chromosome is randomly inactivated. The human X chromosome has large number of genes and contains large euchromatic regions that are highly activating gene regions. The X chromosome also contains the conserved regions that are far shorter in Y chromosome. The X chromosome is large in size and has large number of genes.
Answer:
The correct answer is - no it cant not change from the lytic cycle to the lysogenic cycle.
Explanation:
In the lysogenic cycle, phage DNA is fused into the host genome, where it is moved to the next generation with the host genome. Natural stressors, for example, exposure to toxic compounds or starvation may cause the prophage to extract and enter the lytic cycle where the virus burst or kill the host genome.
So, in the lytic cycle virus kills the host cell s there is no chance or need to change into the lysogenic cycle as whereas in the lysogenic cycle virus incorporated with the host and becomes a chromosome.
