That is true ! .. hopes this helps :)
B. Phenotype
I guess I learned that in term 1 I dont really remeber but I guess
TRna binds to mRNA inside of protein and Rna structure called the ribosome.as tRNA enter slots in the ribosome and bind to codons, their amino acids are linked to the growing polypeptide chain in a chemical reaction.
ACTIVE TRANSPORT: uses energy and require a ligand to bind with receptors.
DIFFUSION: allows small, nonpolar molecule (like oxygen) to move across a cell membrane. It doesn't require energy.
