Classify each RNA post-transcription processing event according to whether it occurs in prokaryotes or eukaryotes.
tigry1 [53]

'RNA is transcribed and translated in the cytoplasm', 'transcription produces an mRNA ready for translation' and 'RNA is proofread for errors' occur in prokaryotes, whereas '5′ cap, 3' poly-(A) tail and RNA splicing' occur in eukaryotes.

The prokaryotic cells (e.g., bacterial cells) do not contain cell nuclei, thereby the messenger RNA (mRNA) must be transcribed and translated in the cytoplasm.

During prokaryotic transcription, the RNA transcript is proofread for errors. In bacteria, DNA polymerases proofread the transcript by using their 3’ → 5’ exonuclease activity.

In eukaryotic cells, RNA processing consists of several mechanisms:

  • A 7-methylguanosine cap (5′ cap) is added to the 5′ end of the precursor messenger RNA (pre-mRNA).

  • A 3' poly-Adenine (A) tail is added to the 3' end of the pre-mRNA.

  • Both the 5′ cap and 3' poly-(A) tail protect the RNA transcript from its degradation by exonucleases.

  • Eukaryotic RNA splicing consists of the removal of non-coding regions called 'introns' and subsequent splicing of the protein-coding regions called 'exons'.

A wave with a height of 5 feet and a wavelength of 15 feet has a wave base of___.
dmitriy555 [2]

A wave with a height of 5 feet and a wavelength of 15 feet has a wave base of <u>7.5 feet</u>.

A. 7.5 feet

<u>Explanation:</u>

Wave base defines the depth of the water when it is in still condition.

Wave base is half of wavelength.

Wave base = wavelength/2

Given,

Wavelength = 15 feet

So, wave base = 15 feet/2 = 7.5 feet

When the wave height is divided by wavelength then it gives the steepness of the wave.

Therefore, the wave base is 7.5feet.

A delta fibers can rapidly transmit pain information to the brain because
kirill [66]
<span>A delta fibers can rapidly transmit pain information to the brain because alpha delta fiber is a type of sensory nerve fiber. Aδ fibers carry cold, pressure and some pain signals. Because Aδ fibers are thinly myelinated, they send impulses faster than unmyelinated C fibers, but more slowly than other, more thickly myelinated "A" class fibers.</span>

The area drained by a river or river system is called a
telo118 [61]

Answer:

A river basin or drainage basin is an area of land drained by a river and its tributaries. The edge of the drainage basin is known as the watershed. This can be compared to a sink or basin, which catches the water falling into it. The water travels towards the centre and leaves the sink through a plug hole.
