Answer:

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.

Which type of mutation is responsible for small changes in a trait
Naddika [18.5K]

<u>Substituion mutation</u>  is responsible for small changes in a trait.

Explanation:

This kind of mutation merely changes the type of nucleotide in the DNA  sequence. The mutation does not cause a frameshift as would a deletion of addition mutation.

A substitution mutation would at worst change an amino acid in the translated protein. This would likely have a slight effect on how the protein folds into an active protein. On the other hand, mutations that cause frameshifts have the biggest effect on the proteins. They change all the amino acids of a protein downstream of the point of mutation.

What is a good way to study experimental subjects in their natural environment
Daniel [21]

<u>Answer</u>: There are numerous factors that influence the behavior and physiology of an individual animal/plant etc. By doing the study in their natural environment, you remove any possible bias caused by this.

Furthermore, an individual's behavior will differ in an artificial experimental setup compared to that observed in a natural setting. When possible, studying the subject in its natural environment is the best experimental method.
