Answer:
3 The mRNA was not bound to by a ribosome 4 tRNA: anticodon matching 5 switching from normal nucleotide for an abnormal one .
Explanation:
3 If the mRNA is not bound to the ribosome then this do not prevent the mRNA from being transported to the Endplasmic reticulum in the cytoplasm.This because binding of ribosome to the mRNA is essential after the mRNA has reached the cytoplasm to initiate the process of protein synthesis.
4 tRNA contains Anticodons that interact with the codon present in the mRNA to bring an amino acid specific for that codon to the A site of ribosome.
5 Mutation at the 3" nucleotide reading frame switch a normal nucleotide for an abnormal one.

Answer:
Gravitropism is the movement or growth of a plant in response to gravity. ... Plant shoots demonstrate negative gravitropism since they grow in the opposite direction of gravity. Gravity is sensed by specialized cells called statocytes, which have statoliths that sink inside the cell.
