Answer:
molecule enter a cekk by passing through the cell membrane
Answer: When there is high magnetic activity, there are more sunspot, this sunpost emit more ultraviolet and visible radiation from the sun.
Explanation:
Sunpost are the most dark and cool area on the sun photosphere. The are like storm on the the sun surface and are characterized by high magnetic field. The originate from the sun and influence galactic rate. They emanate as pair of magnetic disturbances around the sun surface thereby emitting for charged particles from the sun surface which lead to increase in emittion of ultraviolet radiation and visible radiation from the sun.
Answer:
The mRNA would most likely be degraded by nucleases in the cell cytoplasm
Explanation:
The 5'cap on an mRNA strand is necessary to bind ribosomes when the mRNA is being transcribed it also:
- Prevents degradation from nucleases present inside the cell
The poly-A tail helps to:
- Move the mRNA from the nucleus to the cytoplasm
- Prevents degradation from cellular enzymes
- Provides a place for protein binding during translation
Without the cap and tail the mRNA is just a free ranging strand of nucleotides that the cell will try to clean up.
