The answer is To become specialized, cells need to control the production of proteins coded for in their DNA.

All genetic information in a cell's DNA is not fully expressed at all times. On the contrary, in different cell lines, different DNA segments are expressed at different times. Some genes are active in unspecialized cells and later deactivate, some are activated only in specialized cells, for example. These are facultative genes which are active when needed, unlike constitutive genes which are expressed continually. Therefore, to become specialized, cells need to control the production of proteins coded for in their DNA. DNA segments, however, remain in cell and are not destroyed. Also, during the mitosis, all genes are passed, not only required genes.

Alja [10]

Answer:

The answer is C- Lysosomes are present in both bacterial and animal cells.

Explanation:

Lysosomes contain digestive enzymes inside them, which when released break down damaged cell parts. These enzymes are acidic in nature and are separated from other organelles with the help of a membrane.

Lysosomes help in killing bacteria and virus invading the cell body. Lysosomes also take part in the process of cell death known as 'apoptosis'. This happens only when a certain cell is beyond repair.

Lysosomes are present in plant cells, animal cells, bacterial and yeast cells.
