Catalase is an enzyme observed in organisms exposed to oxygen. This enzyme acts to catalyze the conversion of hydrogen peroxide (H2O2) into water and oxygen.

The discovery of a CATALASE-encoding gene provides evidence that the microbe can grow in the presence of oxygen.

Catalase is a key enzyme that protects the cell from oxidative stress damage.

Catalase acts together with the enzyme superoxide dismutase, which in turn catalyzes the formation of H2O2 from superoxide radicals.

In conclusion, the discovery of a CATALASE-encoding gene provides evidence that the microbe can grow in the presence of oxygen.

c. requires the action of initiation factors.
d. begins at a UAG codon downstream of the 5’ UTR of an mRNA molecule.
e. begins only after ubiquitin has been added to the mRNA molecule to be translated.

Answers

Answer:

c. requires the action of initiation factors.

Explanation:

Transcription is the process by which a fragment of DNA (e.g., a gene) is used as a template to create a complementary RNA molecule, usually a messenger RNA (mRNA) molecule which is then used to synthesize a polypeptide chain (i.e., a protein) in the ribosomes by a process called translation. Initiation factors are proteins capable of binding the ribosome in order to promote (or prevent) the initiation of translation. In prokaryotic cells, the initiation factors IF1, IF2 and IF3 (IFs) are required for the selection and the quantity of the protein produced. In eukaryotic cells, translation initiation occurs when an initiator tRNA, 40S, and 60S ribosomal subunits are assembled by eukaryotic initiation factors (eIFs) into an 80S ribosome on the initiation codon of an mRNA. In eukaryotes, translation initiation is promoted and regulated by at least twelve eIFs (e.g., eIF1, eIF1A, eIF2, eIF3, eIF4, eIF5, eIF5A, eIF5B, etc) which are composed of many polypeptides.

Legend has it that there was a less famous geneticist in the 1800s
named Megor Grendel. He did his experiments with the cats that lived in the monastery's barn. Here are some results from one of his 16 crosses:
Cross #3 Maggie (orange) x ? (possibly Tom, or maybe Bill)
Kittens:
1. light orange female
2. dark orange male
3. black female
4. light orange female with white paws
5. black male with white paws
6. orange ? (sex undetermined; died at birth)

Answers

Answer:

Few crosses

The complexity of cat genetics

Crosses not controlled by the researcher

Explanation:

The purpose of this question is to determine why  Megor Grendel is less famous than that of Gregor Mendel.

Gregor Mendel examined pea plants, which have a number of benefits for deducing genetic rules, including:

The researcher has total control over the crosses. Because the peas have both self and cross-fertilization, it is possible to alter the crosses in the simplest way possible. Pea plants may be examined for a greater series of generations than cats or other animals. Because plant genetics is not overly complicated, several traits may be investigated at the same period.

As a result, the primary factors why Megor Grendel's experiments are not well-known:

The presence of only a few crossings: It is impossible to establish a genetic theory with such a small number of crossings on the test subject of the organism. Cat genetics is too complicated therefore, the fur gene color on the X-chromosome, a characteristics mosaic inheritance. As a result, It is much too complicated to deduce an inheritance pattern. Crossings that the researcher cannot fully control. Unlike plants, crosses in animals cannot be totally controlled by the researcher.

As a result, it is impossible to draw any conclusions from them.

Predation is a biological interaction where one organism, the predator, kills and eats another organism, its prey

A relationship in which one species kills and consumes another species which is called as the Predation. So, the correct option is A.

What is Predation?

Predation is defined as the relationship in which one species kills and consumes another species. It is a type of community relationship in which organisms of one species, also known as predator, consume the tissues of organisms of another species, called prey, which means killing the prey and killing all or most of the prey organisms.

Herbivores are explained as predators in which the prey organism is a plant.  Predation is described as the natural way of transferring the energy fixed by plants to higher trophic such as snake eating a frog tiger killing and eating a deer.

Therefore,  the correct option is A.

When curare, a neuromuscular poison, is dropped onto an isolated muscle-nerve preparation in a laboratory, the muscle does not contract when the nerve is stimulated, even though neurotransmitter is released from the nerve cell. Why does this happen

Answers

Answer:

Explanation:

Whenever the nerve terminal's action potential depolarizes, calcium enters the cell through the channels. Calcium allows acetylcholine (ACh) to be released more easily.  These ACh molecules subsequently circulate into the synaptic cleft and attach to the motor end-plate of the nicotinic cholinergic receptors. Acetylcholine molecules connect to nicotine ion-channel receptors present on cell membrane the of muscle cells, enabling the ion channels to open. Calcium ions then enter the muscle cell, kicking off a series of events that eventually result in muscular contraction.

Curare is a kind of neuromuscular relaxant blocker that is non-depolarized in nature. Nondepolarizing muscle relaxants work as competitive agonists, binding to ACh receptors but failing to activate ion channels. As a result, they inhibit ACh from bonding, preventing the development of endplate potentials and inducing muscle paralysis.

A 5'6", 210 pound, 64 year old man had a physical exam prior to his retirement for corporate work. His blood pressure was greater than 180/115 mmHg on three separate days (normal blood pressure is 120/80). Further examination showed normal to low plasma renin activity, elevated systemic vascular resistance (SVR), x-ray showed left ventricular hypertrophy and retinal hemorrhage and cardiac output was 7.2 L/min (normal is 3.5 to 5.5 L/min). Recommended therapy was weight reduction to his ideal weight, low salt diet. If these life style changes did not change his condition the following medication will be started in the following order: oral diuretics progress to beta blockers and then to a vasodilator.

Required:
a. What is the diagnosis for this individual?
b. Why is it suggested that the patient go on a low sodium diet?
c. Explain the site and mechanism of action of each of these prescribed medications.

Answers

Answer:

Explanation:

a.

The individual should be diagnosed for hypertension or high blood pressure.

b.

It is recommended that the patient should take low sodium diet because when sodium or salt enters the blood stream it increases the amount of water or fluids in the blood stream that leads to rise in blood pressure. The blood pressure increases if we take high salt diet due to which arterioles constrict.

c.

Diuretics- Diuretics are the first recommended therapy in treating hypertension. Diuretics such as thizides , pottasium sparing agents. Thiazide acts on distal convoluted tubule that inhibits Na+ and Cl - symporter. Diutetic removes water from body as urine and loss of salt.

Beta blockers - These are antagonists. They block the beta receptors found on the target cell membrane. Beta blockers slows down blood pressure. Atenolol is the beta blocker used for hypertension.

Alpha1 blocker - alpha 1 receptors helps in smooth muscle contraction and vasoconstriction. Vasodilator increases blood flow in the body that are devoid of oxygen that helps to reduce blood pressure.

angiotensin converting enzyme inhibitor - blocks angiotensin converting enzyme that prevents converting angiotensin I to angiotensin II and increases bradykinin levels in the body. These inhibitors helps in lowering blood pressure.
