Elina [12.6K]

Cell is a simple unit of life surrounded by a membrane that contains macromolecules and molecules associated with each other.

<h3>What is cell?</h3>

The smallest unit that makes up all living organisms and the tissues of the body. A cell consists of three main parts i.e. the cell membrane, the nucleus, and the cytoplasm. The cell membrane surrounds the cell and its function controls the substances that go inside of cell and out of the cell. A nucleus is the membrane that enclosed organelle within a cell which contains the genetic material. The cytoplasm is the gel-like fluid inside the cell that provides a medium for chemical reaction.

So we can conclude that Cell is a simple unit of life surrounded by a membrane that contains macromolecules and molecules associated with each other.

Why is dna replication said to be semi-conservative
Neko [114]

During DNA Replication, the DNA molecule unzips itself so that there are two free strands of DNA. Both of those strands then create new complementary strands of DNA. Thus every subsequent generation of DNA uses one of the parent cell's strand of DNA as a template, which is why DNA replication is said to be semi-conservative. Hope this helped!
