g A mutation occurs upstream of gene A in the region encoding the ribosome binding site, making it bind more weakly to the ribos

ome. Predict how this mutation will impact the levels of mRNA and protein produced for gene A. Clearly state how mRNA levels will change and how protein levels will change in this mutant relative to wild type bacteria. Restrict your answer to 1-2 sentences.

Answer:

it is expected that the mutation results in a reduced initiation of translation and thereby decreasing the level of the protein A, while it does not change the level of mRNA A

Explanation:

Translation in bacteria starts with the formation of the initiation complex which is composed of the small ribosomal subunit, the messenger RNA (mRNA), initiation factors and the initiator transference RNA (tRNA) containing N-formyl-methionine. The small ribosomal subunit binds to a polypurine stretch of variable length in the mRNA called 'the Shine-Dalgarno sequence'. A mutation in this sequence reduces the affinity of the ribosome for the mRNA, thereby, in this case, decreasing the level of protein A. Since transcription occurs before translation, it is expected that this mutation does not change the level of expression of the mRNA A.

The ___________ is an important element of the drug experience because it affects how much of a drug reaches its site of action
Marysya12 [62]

Answer:

Route of administration

Explanation:

Drugs may be defined as the chemicals that are given against the particular disease for the treatment of the patient. The drugs must be given in the proper amount as directed by the medical practitioner.

The effects of the drugs depend on the individual and its route of administration. The oral administration of drug is more common but a diabetic patient needs to given drug intravenously. Intraperitoneal drug route is given to show the effect of drug quickly and drug cannot infiltrate a blood vessel.

Thus, the answer is route of administration.

In the Krebs Cycle of cellular respiration, pyruvate is used to make
Nikolay [14]

Answer:

b. carbon dioxide

Explanation:

This metabolic pathway is called the Krebs cycle after the scientist who first discovered it in 1937. The Krebs cycle is further broken down by pyruvic acid, obtained in the glycolysis process. The process proceeds in two stages. The first is the degree of decomposition of the bicarbonate residue.

The Krebs cycle is the main metabolic pathway for the breakdown of organic matter and the production of energy in the form of reduced coenzymes, which will then be incorporated into ATP.

What role does cellular respiration play in the carbon cycle?
Liono4ka [1.6K]
During cellular respiration, carbon dioxide is released to the atmosphere during the formation of acetyl coenzyme A<span>. This step involves the oxidative decarboxylation of pyruvic acid, the result of which is carbon dioxide. This carbon dioxide is uptaken by plants and used in the process of photosynthesis to produce glucose.</span>

I am a unicellular microorganism that lives in the hypersaline waters of Southeastern Australia. What Kingdom do I belong to?
scZoUnD [109]

Answer:

The correct answer is - Archaea or archaebacteria.

Explanation:

Archaea is the domain and the kingdom of the single-cell prokaryotic organisms as they lack a nucleus. These organisms are present in extreme habitats such as hot springs, high saline water. These organisms can live in extremely aggressive environments which makes it a uniqe characteristic of this organism.

In the given condition the organism that lives in hypersaline water is most likely a member of the  Archaea domain or Archaebacteria kingdom as it is found in the hypersaline waters of Southeastern Australia and unicellular organisms.
