The ability for cancer cells to divide
indefinitely is made possible because Cancer cells rebuild their telomeres
after every cell division.
At each end of the chromosome, there is a
region of repetitive nucleotide
sequences, this is called telomere and when a cell begins to become cancerous,
it divides more often. Telomeres are crucial for the survival of cancer
cells and they are
maintained by an enzyme called telomerase.
Answer:
The correct answer is -
A.It is destroyed.
Explanation:
The lytic cycle is considered as one of the two reproductive cycles that virus use for its reproduction (the other cycle is the lysogenic cycle).
This cycle results in the destruction of the host cell.
Bacteriophages (virus that infects bacteria) use this cycle and referred as virulent phages.
There are basically five steps in this cycle -
Attachment of virus with the host cell membrane, penetration of the genome, which is followed by biosynthesis using host machinery, assembly of virus particles, and finally release, causing host cell destruction.
Thus, option A is the right answer.
