(1) Both statements 1 and 2 are true and statement 2 is the correct explanation of statement 1.
Nucleus:
- the cell's core. item contains genes, which are present on chromosomes and act as instructions. Your DNA is made up of your chromosomes.
- Half of a mother's genes are passed on to her offspring.
- Half of a father's genes are passed on to his offspring.
- Thus, the child inherits a combination of genes from both parents that manifest as inherited traits.
- We may argue that the nucleus is in charge of this since it houses the chromosomes, which contain the genes that carry genetic information.
- The nucleus functions as the cell's central remote control.
- By instructing the cell on what to do, how to develop, and when to reproduce, it serves as the brain of the cell. The genes of the cell are located in the nucleus.
- The nucleus is encircled by a membrane, a slender covering that permits substances to enter and exit the cell.
