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.

What is a gene? a single strand of DNA. the fundamental unit of heredity. a single nucleotide. the fundamental unit of DNA

const2013 [10]

Answer:

the fundamental unit of heredity

Explanation:

DNA is a double stranded helix structure. Each strand is made up of a string of nucleotides.

A gene is a region of DNA, usually tens of thousands of nucleotides long. At the simplest level, one gene encodes for one trait. Therefore, the gene can be described as the fundamental unit of heredity.

Genes work by coding for specific proteins, which carry out essentially all the functions in the cell.
