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'.

The Earth is more massive than the moon. How will a person’s weight on the moon compare to their weight on Earth?
Rom4ik [11]

Answer:

The weight of a person on the moon is less, compared to their weight on Earth.

Explanation:

Gravitation is a force. Gravity is the force that tries to pull two objects toward each other.

Anything which has mass, also has a gravitational pull. The more massive an object is, the stronger its gravitational pull is. So because the moon iless massive than the earth, you will experience a less gravitational pull and therefore a you will experience less weight on the moon compared to your weight on earth.

EXTRA

The Gravitational pull is difined by the force that arises of masses of two objects in relation to their distance.

Earth's gravity is what keeps you on the ground and what causes objects to fall back to earth.

You can experience a change in gravitational pull on earth yourself, in an exelerating or decelerating elevator.

Which of the following statements about vicariance and dispersal is most accurate?
V125BC [204]

Answer:

Answer is A. Vicariance does not require organisms to disperse.

Explanation:

Vicariance occurs when there is a sudden occurrence barrier , such as geographical area barrier that cause the isolation of species of organisms.

Dispersal involves the movement of the organism while vicariance is the change in environment due to sudden occurrence in the area.

In this case, vicariance  does not involve movement of organisms while dispersal involves movement of organisms.
