Answer:
Channel protein.
Explanation:
Channel protein have gate that opens and close which allow the passage of polar substance or ions to move to permeable membrane of the cell by diffusion. They are water filled and allow the movementof charged molecules inside and outside the cell membrane i.e polar molecules move through non polar bilayer of the cell membrane.
Groups of 3 bases are referred to as codons.
Each codon codes for an amino acid.
A group of amino acids makes a protein.
These proteins are then used to carry out basic life functions
The function is mixing and propulsion
answer: D. RNA to protein
