explain why the hybrid gene mrna transcript does not undergo 3' cleavage and polyadenylation.

Answers

Answer 1

The hybrid gene mRNA transcript does not undergo 3' cleavage and polyadenylation because of the potential effects of alternative splicing, premature termination, and altered gene structure that can result from the fusion of two separate genes.

The hybrid gene mRNA transcript does not undergo 3' cleavage and polyadenylation due to the following reasons:

1. Alternative splicing: Hybrid genes are formed through the fusion of two separate genes. This can lead to alternative splicing events that might eliminate the 3' cleavage site and polyadenylation signal, preventing the transcript from undergoing the usual 3' processing.

2. Premature termination: The fusion event may lead to premature termination of the transcript, resulting in the loss of the 3' cleavage site and polyadenylation signal, thereby preventing 3' cleavage and polyadenylation.

3. Altered gene structure: The fusion of two separate genes might disrupt the gene structure, specifically the 3' untranslated region (3' UTR) which contains the cleavage and polyadenylation signals. If these signals are disrupted or absent, the hybrid gene mRNA transcript will not undergo 3' cleavage and polyadenylation.

Enzymes known as lyases participate in cleavage reactions.

These reactions involve breaking down a larger molecule into smaller molecules without the use of water. Lyases can also help form new bonds in the reverse reaction, known as synthesis.

In biochemistry, a lyase is an enzyme that catalyzes the breaking (an elimination reaction) of various chemical bonds by means other than hydrolysis (a substitution reaction) and oxidation, often forming a new double bond or a new ring structure. The reverse reaction is also possible (called a Michael reaction). For example, an enzyme that catalyzed this reaction would be a lyase:

All four mediums contain different soil nutrients.

All three plants require equal amounts of oxygen and water.

Plant 1 requires more light than Plant 2 and Plant 3 in order to reach maximum growth.

Plant height growth was measured by a computer program.

Correct answer:

Plant 1 requires more light than Plant 2 and Plant 3 in order to reach maximum growth.

Explanation:

The correct answer is C, in each equation are equal when d is undefined, which means the plants will eventually be the same height.

Both equations have the same slope of 2.5, which means that the plants are growing at the same rate each day. The y-intercepts are different, but that doesn't matter since the scientist is looking for the point where the two plants have the same height.

To find that point, we need to set the two equations equal to each other and solve for d:

2.5d + 10.0 = 2.5d + 7.5

2.5d - 2.5d = 7.5 - 10.0

0d = -2.5

d = N/A

Since 0 times any number is always 0, we end up with a 0d term on the left side, which means we can't solve for d. However, we can see that the values for y in each equation are equal when d is undefined, which means the plants will eventually be the same height.

Because it is polar, hydrogen bonds can be formed, which makes it possible for ions and other polar molecules to dissolve in water.

Hydrogen bonds are a special kind of weak bonding caused by water's polarity. The close proximity of the molecules in liquid water is made possible by hydrogen bonds.

Water works well as a solvent. Water is able to hold heat more effectively than many other substances due to the hydrogen bonds that connect its molecules.

Water's extremity permits it to disintegrate other polar substances without any problem. When a polar substance is placed in water, its molecules' positive ends are attracted to the negative ends of the water molecules, and vice versa.

The ability of water molecules to attract other water molecules, which makes water a "sticky" liquid, is described by the property of cohesion. The difference in charge between hydrogen ions that are slightly positive and other ions that are slightly negative results in the attraction of electrostatic force known as hydrogen bonds.

T he sun’s rays strike latitude 23. 5°S at an angle of 90 degrees on December 21.

The angle at which the sun's rays strike a specific latitude depends on the tilt of the Earth's axis in relation to its orbit around the sun. This phenomenon is known as the axial tilt or obliquity. The Earth's axial tilt is approximately 23.5 degrees, and it causes the changing of seasons and the variation in the angle at which sunlight strikes different latitudes throughout the year.

On December 21st, during the Southern Hemisphere's summer solstice, the sun is directly overhead at the Tropic of Capricorn, which is located at latitude 23.5 degrees south. This means that the sun's rays strike latitude 23.5°S at an angle of 90 degrees on December 21st.

False. Extinction is a term used in behavioral psychology to describe the gradual weakening and eventual disappearance of a previously learned behavior.

It occurs when the previously reinforced behavior is no longer followed by the reinforcing consequence, resulting in a decrease in the frequency of the behavior over time. However, extinction does not necessarily involve the withholding of reinforcement. Rather, it involves the lack of reinforcement or the removal of the reinforcing consequence that previously maintained the behavior. In some cases, extinction may involve the withholding of reinforcement, but it can also occur when reinforcement is simply no longer provided.

For example, if a child is used to receiving a reward for completing their homework, but the reward is suddenly removed, the behavior of completing homework may gradually decrease over time as a result of extinction. In this case, the reinforcing consequence (the reward) has been removed, but it was not necessarily withheld.

A client who is obese is to start receiving amphetamine as part of the treatment. Which factor should the nurse prioritize in the preadministration assessment? A) Temperature B) Weight C) Blood glucose level D) Arterial blood gas results

Answers

The nurse should prioritize weight factor in the proadministration assessment. The correct option is (B)

The nurse should prioritize the client's weight in the proadministration assessment because amphetamine is a stimulant that is often used to treat obesity. The dose of amphetamine is based on the client's weight, so it is important to accurately measure the client's weight before administering the medication.

Additionally, obesity can increase the risk of adverse effects from amphetamine, such as cardiovascular events, so it is important to closely monitor the client's response to the medication.

While temperature, blood glucose level, and arterial blood gas results may be important factors to assess in certain situations, they are not directly related to the administration of amphetamine for obesity.

Replacement AnalysisThe Everly Equipment Company's flange-lipping machine was purchased 5 years ago for $50,000. It had an expected life of 10 years when it was bought and its remaining depreciation is $5,000 per year for each year of its remaining life. As older flange-lippers are robust and useful machines, this one can be sold for $20,000 at the end of its useful life.A new high-efficiency digital-controlled flange-lipper can be purchased for $140,000, including installation costs. During its 5-year life, it will reduce cash operating expenses by $45,000 per year, although it will not affect sales. At the end of its useful life, the high-efficiency machine is estimated to be worthless. MACRS depreciation will be used, and the machine will be depreciated over its 3-year class life rather than its 5-year economic life, so the applicable depreciation rates are 33.33%, 44.45%, 14.81%, and 7.41%.The old machine can be sold today for $50,000.
