Answer 1

of which chapter you need notes

Answer 2

Answer:

Hello mate. Here is your answer.

The nucleus is an important organelle responsible for controlling nearly all forms of cellular activities. Almost every kind of cell in existence is classified based on the presence or absence of the nucleus within its cell (classified either as a eukaryotic or prokaryotic cell.)

What is a Nucleus?

The most integral component of the cell is the nucleus (plural: nuclei). It is derived from a Latin word which means “kernel of a nut”.

Nucleus Definition: A nucleus is defined as a double-membraned eukaryotic organelle that contains the genetic material.

As stated above, the nucleus is found only in eukaryotes and is the defining characteristic feature of eukaryotic cells. However, some cells such as RBCs do not possess a nucleus though they originate from a eukaryotic organism.

Nucleus Structure

It is generally the most prominent organelle in the cell.

The nucleus is completely bound by membranes.

It is surrounded by a structure called the nuclear envelope.

This membrane separates the contents of the nucleus from the cytoplasm.

The cell’s chromosomes are also enclosed within it.

DNA is present in the Chromosomes and they provide the genetic information required for the creation of other cell components and also for reproduction of life.

Nucleus Function

It contains the cell’s hereditary information and controls the cell’s growth and reproduction.

The nucleus has been clearly explained as a membrane-bound structure that comprises the genetic material of a cell.

It is not just a storage compartment for DNA but also happens to be the home of some essential cellular processes.

First and foremost, it is possible to duplicate one’s DNA in the nucleus. This process has been named DNA Replication and creates an identical copy of the DNA.

Creating two identical copies of the host or body is the first step in cell division, where each new cell will get its own set of instructions.

Secondly, the nucleus is the spot of transcription. Transcription is the process of creating different types of RNA from DNA. Transcription would be a lot like making copies of individual pages of the human body’s instructions that can then be passed out and read by the rest of the cell.

The central rule of biology states that DNA is copied into RNA, which is then turned into protein.

Hope u liked it. Plzz mark this as brainliest. I have read ur msg but if u can join little bit later around 12 then it would be much better. I will try my best to came at 11.

Thank u.
