Answer:
Nucleic acids are the most important macromolecules for the continuity of life. They carry the genetic blueprint of a cell and carry instructions for the functioning of the cell.

The answer is: from mother
In a human diploid somatic cell (2n), there are<span> in total 46 chromosomes</span> - 22 autosomal chromosomes present in two copies and 1 pair of sex chromosomes. This means there are 23 pairs of chromosomes. In males, there is one X and one Y chromosome (XY) while in females, there are two XX chromosomes (XY).
During the formation of gametes, a female could give only X chromosomes, so gametes from the mother contain one X chromosome. But, a male could give X or Y chromosome, so gametes from the father contain either X or Y chromosome.
Female gamete and male gamete fuse to form a zygote. Male zygote must contain both X and Y chromosome. It inherits Y chromosome only from the father, so X chromosome must be inherited from the mother.
The order from what I remember is
Interphase
Prophase
Metaphase
Anaphase
Telophase
Cytokinesis- also known as daughter cells
Answer:
protein capsid
Explanation:
virus is a disease causing agent containing a protein capsid which is made up of protein called Capsomere. The capsid contain the genetic information or material of virus.
Virus which do not contain envelop is called naked virus.
the uses of capside are to protect the genetic material, transfer the genome and interaction with host cell.
