It's carbon because it is in all plants and fossil fuels. Hope this helps and is correct.
South American Tropical Rainforest is where you would find the greatest variety of species.
Ketogenesis is the conversion of acetyl CoA into Ketone bodies. CoA stands for fatty acid fragments, not whole fat. The fat moelcule is first broken into fatty acids and then the ketogenesis process takes place. The conversion of acetyl CoA into ketone bodies happens whenever acetylCoA cannot be oxidized.
Answer:
An Oc mutation on the bacterial chromosome can affect the expression of structural genes on a F plasmid.
Explanation:
An Oc mutation is a mutation in which operator of an operon is constitutively active i.e. repressor fails to bind the operator which leads to unregulated gene expression.
An Oc mutation do not affect the expression of structural genes on F plasmid because <u>an operator is a cis regulatory element and therefore it can only affect the genes which are located on the same DNA</u>. F plasmid genes are located on the plasmid not on the main chromosome of the prokaryotes while tryptophan or lac operon system is in the main chromosome that is why an Oc mutation will not impact genes on plasmid.
