The answer is most likely B). 'The harmless bacteria would not have been transformed, and the mice would have lived,' because, then bacterium transform, they use the genetic material present in their environment to do so, and when Avery destroyed the nucleotide bases(Genetic material) with an enzyme he destroyed any chances that the bacteria would have had at transforming into the virulent strain.
Answer: D. Jacob and Monod
Explanation:
An operon is a region of DNA that consists of a single gene regulated by more than one promoter. An operon is a region of RNA that consists of the coding regions of more than one gene. RNA polymerase is the enzyme that binds to promoters and transcribes the coding regions of genes into RNA.
Jacques Monod was the first to demonstrate the preference for certain substrates over others through his studies of E. coli’s growth when cultured in the presence of two different substrates simultaneously.
Answer:
D. mRNA.
Explanation:
Polyadenylation is defined as the addition of poly (A) to messenger RNA. This tail is made up of several adenosine monophosphates (adenine bases). In eukaryotes, polyadenylation is part of the process in which messenger RNA is formed for subsequent translation. Therefore, it is part of the process of gene expression.
<h2>(d) is the correct option </h2>
Explanation:
Flank pain refers to discomfort in upper abdomen or back and sides
- The kidneys are located on either side of the spine, under the rib cage
- The right kidney hangs a little lower than the left, making it even more likely to cause lower back pain if it's infected, irritated, or inflamed
- A kidney contusion, often called a kidney bruise, occurs following blunt trauma or direct impact to the lower back
- This trauma leads to bleeding inside of the kidney which may also cause pain, tenderness, and discoloration of the skin
- The back muscles and rib cage of human body protect the kidneys
- If a kidney becomes injured there is a chance that one has injured other muscles and bones
