Which of the following is/are true about eukaryotic transcription?

A) RNA polymerases bind directly to the core promoter (TATA box)

B) Transcription factors are required for RNA polymerase ll-dependent transcription

C) RNA polymerase ll transcribes the protein-coding genes

D) Poly-A tail is the last part of transcript synthesis by RNA polymerase ll.

E) rho factor participates in transcription termination

Answers

Answer 1
The answer is D I believe. 20 characters
Answer 2

Answer:

Option B is true (Transcription factors are required for RNA polymerase ll-dependent transcription)

Explanation:

Option B is correct because many different transcription factors are involved in the eukaryotic transcription, particularly genes transcribe by RNA polymerase II. TFIID, A, B, F, E, and H are general or basal transcription factors of human.

Option A is wrong because RNA polymerase II first bind with the general transcription factor, TFIID. TFIID recognise the TATA box and forms a platform for TFIIB binding.

Option C is wrong because RNA polymerase II transcribe protein coding genes but it also transcribe small nuclear RNAs (snRNAs).

Option D is incorrect because transcription of poly-A tail is synthesized by template-independent RNA polymerase called poly(A) polymerase.

Option E is also incorrect- rho factor or rho-dependent termination is used by bacterial transcription termination process.

Eric has made a terrarium, a closed container with plants in it, and he has put

water to his terrarium again? Why or why not?

Answers

Answer:

Yes

Explanation:

The water will be used by the plants sooner or later so their basic metabolic needs can be achieved. Also, the plants will loose their water by transpiration, in order to produce their carbohydrates. Therefore the amount of water will not be enough and has to be replenished.

In fruit flies, the gene for eye color is located on the X chromosome, and the red eye allele (R) is dominant
to the white eye allele (r). A carrier female is mated with a male fly with genotype X
rY. Which of the
following statements best describes the expected outcome of the cross?
a. The chance of an offspring having red eyes is 75%
b. The chance of an offspring having white eyes is 50%
c. The chance that a male offspring will have white eyes is 0%
d. The chance that a female offspring will have red eyes is 100%

Answers

Answer:

b. The chance of an offspring having white eyes is 50%

Explanation:

So the genotype of the male fly is X^r Y. This means the male has white eyes because he only has one X chromosome, so he will express whatever allele is on that chromosome.

The genotype of the female fly, though, is X^R X^r. This is because carriers are heterozygous for traits, and the sex chromosomes of most females is XX (with some exceptions, like XXX, or X (Turner syndrome)).

If we cross this, what are the outcomes? Do a Punnett square. You get the genotypes of X^r X^R, X^r X^r, X^R Y, and X^r Y. The expected phenotypes are a red eye female, white eye female, red eye male, and white eye male.

Now, let's look at the choices:

A.: The chance of an offspring having red eyes is not 75%; it is 50%.

B.: The chance of an offspring having white eyes is 50%!!!

C.: The chance that a male offspring will have white eyes is 50%, not 0%.

D.: The chance that a male offspring will have white eyes is 50%, not 100%.

Which best describes this excerpt?
Read the excerpt from "A Simple Way to Create Suspense".
For instance, heading toward a movie review program,
remember we asked: Who was the studio's first choice for

Eastwood wasn't the first choice?) But—and this was the
lesson—the success of the tactic didn't depend on intrigue.
Even viewers with no interest at all stuck around to find out.
Humans are hard-wired. They need to know. Even viewers
who knew the answer for sure stuck around, in order to be
gratified. The gap was bridged, and the danger averted. (It
was Frank Sinatra. You waited, right?)
O The central idea of this excerpt is that Clint Eastwood was
not the original choice for the Dirty Harry movie.
O The central idea of this excerpt is that intrigue is the most

Another student claims that mitosis is the longest stage. Using evidence from the photo, determine which student is correct and why. A) Mitosis is the longest stage because anaphase requires more time to separate chromatids. B) Interphase is the longest stage because chromosomes are visible in the majority of the cells. C) Mitosis is the longest stage because the majority of the cells in the photo are replicating their DNA. D) Interphase is the longest stage because the majority of the cells in the photo have uncondensed chromatin and are not dividing.

Answers

Answer:

B

Explanation:

the longest phase in the cell division is interphase because the DNA replication occurs in this phase

As per the image interphase is the longest stage because the majority of the cells in the photo have uncondensed chromatin and are not dividing. The correct option is D.

What is cell cycle?

The cell cycle, also known as the cell-division cycle, is the sequence of events that occurs in a cell that causes it to divide into two daughter cells.

A cell cycle is the series of events that takes place in a cell as it grows as well as divides.

A cell spends the majority of its time in what is known as interphase, where it grows, replicates its chromosomes, and prepares for cell division. The cell then exits interphase, goes through mitosis, and divides completely.

Interphase is the longest stage, according to the image, since the maximum of the cells in the photo have uncondensed chromatin as well as are not dividing.

Thus, the correct option is D.

Answers

Answer:

Transparent objects allow all the light to pass through them. Opaque ones allow no light to pass through. Translucent allows light to go through but the area in it is no visible to determine the object

Explanation:

Think of Transparent as a window u can see straight through it is clear.Think of Translucent as a window with cold fog on the window light can come through it but you can't see whats outside.Think of Opaque as a black chalkboard light reflect on it but light cannot go through it

Answer:

Transparent: light will completely pass through and is very visible through the transparent object. For example, sunlight through a window

Translucent: some light will pass through, will be somewhat visible. For example, if you put a flashlight or your phones flash against a piece of paper, the light will pass through but not as much as light through a window

Opaque: you will not be able to see light through an opaque object, for example, putting a flashlight against a large book or a rock. No light will pass through the object.

Storing hormones, smooth and cardiac muscles are the correct answers.

Storing hormones is not function of skeleton system. Skeleton system protects internal organs such as heart, kidney and lungs etc. It is also responsible for the movement of the muscles as well as produces blood cells because of the presence of bone marrow.

Smooth and cardiac muscles can contract without nervous system stimulation because they are involuntary Muscle which is beyond the control of the nervous system so we can conclude that storing hormones, smooth and cardiac muscles are the correct answers.
