1,why dna coiled to histone protien 2,what is difference bewteen co-factor and prosthetic group 3,why child get mitrochondrion from their mother cell not from their father cell (explain).

DNA coiled to Histone protein.

Explanation:

1) DNA wrap itself around the histone protein due to the negative charge on the histone, that packed DNA tightly so that it can't be used in protein synthesis.

2) Prosthetic groups are itself co-factors that bind tightly to enzymes or proteins. they can be organic or metallic ions and attached to proteins by covalent bond.

3) The transfer of mitochondrial DNA (mtDNA) from mother to  her offspring is known as  maternal inheritance. only female can transmit  mtDNA beacuse, it can be transmitted through female eggs only. One can inherit mtDNA from exclusively their mother.

that is true   : ) hope this you
