Which of the following statements about eukaryotic mRNA processing is not correct?
ch4aika [34]

Answer:

The correct answer will be option-D.

Explanation:

In eukaryotes, the process of transcription takes place inside the nucleus whereas translation takes place in the cytosol. So, mRNA has to export to the cytosol from the nucleus.

Before export, the post-transcriptional modification takes place like 5' capping, 3' tailing and splicing mechanism.

The capping is done at 5' end by adding modified guanine (G) nucleotide which protects the mRNA from exonuclease activity and tailing is done at 3' end by adding adenine nucleotides which provides stability to the mRNA.Splicing removes the junk DNA called introns and joins the exons before export.

Thus, option-D is the correct answer.

"The ____ is the division of the autonomic nervous system that coordinates arousal and involves the expenditure of energy."
finlep [7]

Answer:

Sympathetic nervous system

Explanation:

The sympathetic nervous system is the part of the autonomic system of neurons which gets activated in the condition of stress.

The stress conditions activate the sympathetic nervous system which prepares the human body for the stress condition by either fight or flight mode.

The fight or flight responses requires a large amount of energy which are produced by the activation of the parasympathetic energy therefore the sympathetic system involves the expenditure of the energy. The system is also involved in sexual arousal.

Thus, the Sympathetic nervous system is the correct answer.
