Trna molecules are ejected from their amino acid in which step of translation?

The correct answer will be at elongation step of translation.

Explanation:

Translation is a process during which synthesis of proteins takes place inside a special organelle called ribosomes in cytoplasm or ER of the cell. It proceeds in three stages: Initiation, elongation and termination.

tRNA molecules are involved during elongation phase of the translation where they add amino acids to nascent protein chain.

tRNA gets charged with amino acids at its 3' end and becomes charged aminoacyl tRNAs which binds to A (aminoacyl) site of the ribosomes where it forms peptide bonds growing polypeptide chain. Then it binds to P (peptidyl) site of ribosomes where an initiation complex with free A site accepts tRNA after start codon chain elongation takes place. In last, they binds to E (exit) site of ribosomes where they gets dissociated from the ribosomes so that they can be recharged again with free amino acids.

Thus, during elongation phase they gets dissociated from the ribosomes.

i got something better   a catchphrase here it is

ahem  

ahem

what the squwock

explanation:

yes, because even though a theory has a  lot of evidence to support it, it is not always true
