Answer:

a variety of genes are involved in the control of cell growth and division. the cell replicates itself in an organized, step by step fashion known as the cell cycle.

Explanation:

tight regulation of this process ensures a dividing cell's DNA is copied properly, any errors in the DNA are repaired and each daughter cell receives a full set of chromosomes.

Can somebody give me the answer for these...

labwork [276]

Answer:

1. Life cycle of a cell starts from

G1 phase - S phase (synthesise phase) - G2 phase - mitosis.

2. By mitosis bcoz it restore nucleo cytoplasmic ratio means ploidy of cell remain same.

3. Bcoz of transformation of normal cells into cancerous cells by Carcinogens present in tobacco.,drugs .etc

4 mitosis occurs in plants animals

Binary fission occurs in bacteria and other single celled organism.

Both give rise to two daughter cells.

5.sex cells (n) are produced by meiosis from gamete mother cells(2n).

6.in meiosis ploidy of cell become half

Means diploid cell form haploid cells

And 4 haploid daughters cells are formed.

In mitosis, ploidy of cell remain same

Means haploid form haploid and diploid form diploid.

1 cell form 2 daughter cells.

Hope this helps you.. Frnd ❤️
