Answer:
As the outer layer of your skin separates your body from its environment, the cell membrane (also known as the plasma membrane) separates the inner contents of a cell from its exterior environment. This cell membrane provides a protective barrier around the cell and regulates which materials can pass in or out.
Explanation:
Although the DNA packaging with histones proteins is mean to form nucleosomes (groups of 8 histones proteins), the higher structures why the genetic material is packaged with those molecules is to form chromosomes, as you said.
The first step in protein synthesis is the transcription of mRNA from a DNA gene in the nucleus. At some other prior time, the various other types of RNA have been synthesized using the appropriate DNA. The RNAs migrate from the nucleus into the cytoplasm.
The correct option is (D).
An amino group and carboxylic acid group are the most basic common components in all amino acids. While, R group in the amino acids always different (here R describes the alkyl group).
Organic substances having both amino and carboxylic acid functional groups are known as Amino acids. Alpha-amino acids, which make up proteins, are by far the most significant of the hundreds of amino acids found in nature.
Amino acids perform a variety of processes in our body including muscular growth, delivering nutrition, prevent disease, and many more. A lack of certain amino acids can lead to a variety of health concerns, including lowered immunity, digestive disorders, depression, less mental alertness, slower child growth, etc.
There are total 20 amino acids, out of them 9 are essential amino acids means they are not synthesis by our body they must be taken outside from diet and nutrition.
