Answer:
See the answer below
Explanation:
A DNase is also known as deoxyribonuclease and it is an enzyme that catalyzes the degradation of deoxyribonucleic acid by cleaving the phosphodiester linkage in their structures. Thus,<em> if the RNA is treated with a DNase before the plants are exposed to it, it will not make any difference. The plants will develop the same types of lesions as if they have been exposed to the mosaic virus.</em>
Unlike DNase, RNase is a ribonuclease, an enzyme that is capable of carrying out catalytic degradation of ribonucleic acids. <em>This means that if the RNA is treated with RNase before the plants are made to be exposed to it, they will not develop the lesions because the RNA would have been degraded by the enzyme.</em>
A protease is an enzyme that degrades the structure of proteins. <em>Treating a RNA with protease will thus have no effect on the structure of the RNA. Exposing the plants to the protease-treated RNA will make no difference. The plants will still come down with the lesions as if they have been exposed to the virus. </em>
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.
Answer:
an autotroph is an organism that can produce its own food using light water carbon dioxide or other chemicals because autotrophs produce their own food they are sometimes called producers
