As alluded to above, the CTD undergoes dynamic changes in phosphorylation during transcription elongation. Very simply, the CTD is phosphorylated on Ser2 by CDK9, while Ser5-P is removed by Ser5 phosphatases, and, toward the end of genes, the CTD is dephosphorylated by Ser5 and Ser2 phosphatases.

Answer 2

Answer:

Final answer:

Phosphorylation of the CTD of RNA polymerase II occurs during the initiation phase of transcription. It 'activates' the RNA polymerase II and is crucial for the transition to the elongation phase.

Explanation:

The phosphorylation of the CTD (C-terminal Domain) of RNA polymerase II happens during the initiation phase of transcription. This process is crucial for the transition from the initiation to the elongation phase of transcription.

Specifically, when the RNA polymerase II prepares to read the DNA strand and start RNA synthesis, the CTD, a part of the RNA polymerase II which is composed of many repeats of a seven-amino-acid sequence, undergoes phosphorylation.

The phosphorylation essentially 'activates' the RNA polymerase II and aids in the recruitment of various factors necessary for effective and correct transcription.

A mixture of oxygen, hydrogen, and nitrogen exerts a total pressure of 378 kPa. If the partial pressures of oxygen and hydrogen are 212 kPa and 101 kPa respectively, find the partial pressure exerted by nitrogen.A. 65 kpa
B. 313 kpa
C. 166 kpa
D. 277 kpa

Answers

As we know that

P total = pO +pH +pN

P = P1 + P2 + P3

378 kPa= 212 kPa + 101 kPa + P(H2)

P(H2) = 65 kPa

partial pressure is 65

so correct option is A

hope it helps

Answer:

The correct answer is option A.

Explanation:

Total pressure of mixture = p = 378 kPa

Partial pressure of the oxygen gas = $p^o_(O_2)=212 kPa$

Partial pressure of the hydrogen gas = $p^o_(H_2)=101 kPa$

Partial pressure of the nitrogen gas = $p^o_(N_2)=?$

As we know that total pressure is sum of partial pressures exerted by all the individual gases.

$p=p^o_(O_2)+p^o_(H_2)+p^o_(N_2)$

$378 kpa=212 kPa+101 kPa+p^o_(N_2)$

$p^o_(N_2)=378 kPa - 212 kPa-101 kPa=65 kPa$

65 kPa the partial pressure exerted by nitrogen.

Monosaccharides are used by plants and animals as a source of a) building muscle b) hormone balance c) fat storage d) a source of energy

Answers

Answer;

D. a source of energy

Monosaccharides are used by plants and animals as a source of energy.

Explanation;

Monosaccharides are the simplest carbohydrates and the building blocks of other carbohydrates. They include glucose, fructose, galactose,etc
Monosaccharides are used as a source of energy in both plants and animals. They are used to produce and store energy. Most organisms create energy by breaking down the monosaccharide glucose, and harvesting the energy released from the bonds.

monosacharides are used by plants and animals as a source of energy. your answer is d.
