What is responsible for termination of transcription in eukaryotic protein-coding genes?
kupik [55]

Answer:

<h2>A polyadenylation signal or poly(A) </h2>

Explanation:

Termination. In eukaryotes, transcription is terminated differently for the all 3 different RNA polymerases. Transcription is terminated by two elements: i) a poly(A) signal and ii) a downstream terminator sequence.

In eukaryotic protein-encoding genes, the cleavage site in the RNA occurs between an upstream( the sequence before the cleavage site) AAUAAA  and a downstream GU-rich, separated by approx 40-60 nucleotides. After they both have been transcribed, a protein knows as CPSF  and another protein called CstF( in humans)  helps in termination.

If you mix the Pattersonase gene sequence with EcoRI, how many
miv72 [106K]

Answer:One EcoRI site can be found in 4096 bp.As EcoRI can not cut a sequence if it is not complete, so 732421 recognition sites in human genome can be found. As you know human genome is linear genome, and when you digest it with Restriction Endonuclease having one recognition site, it always gives two fragments.

I NEED ANSWER NOW!!!!!!!!
ivolga24 [154]

Answer:

The answer is B, How does gravitropism affect plant growth?

Explanation:

According to Google:

"Gravitropism (also known as geotropism) is a coordinated process of differential growth by a plant or fungus in response to gravity pulling on it."

So, since the students put the pots on their sides, and they say that the bean plants bend upwards, then option B is the only logical explanation for the plants' behavior.

Have a BE-A-U-TIIFUL day!! \(^u^\)
