Answer:
True
Explanation:
Protein purification involves isolating them from their source based on differences in their physical properties. The objective in chromatography is to retain the largest amount of functional protein with the least number of contaminants, which is why an assay needs to be performed for each type of protein.
Pressure of water increases with depth. Thus, the balloon decreases in volume as it is forced deeper. The correct answer is C).
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.
It depends on the statement, but most aren't true from my perspective. Perspective also determines the validity of the statement.
