Answer:
A site
Explanation:
During the process of translation, ribosomes play a major role in connecting mRNA codons with tRNA anticodons. Ribosomes are composed of two subunits which consist ofproteins and rRNA. The tree sites of ribosomes are:
- P site or peptidyl site-this site binds to the tRNA which holds the growing polypeptide chain.
- A site or acceptor site-this is a site of peptide bond formation between the growing polypeptide and the next incoming amino acid
- E site or exit site-the site for the final binding of t-RNA .
Answer:
Molecules carrying amino acids are positioned in the ribosome’s two docking sites.
Explanation:
A ribosome is a molecular machine that coordinates protein assembly.
- A ribosome brings together correctly the mRNA, which needs to be translated, and the tRNA, which assists in the translation process, to come together correctly.
- During translation, tRNA molecules carrying amino acids are positioned in the ribosome’s two docking sites.
- After the translation, the tRNA disassemble and is being reused many times.

A neuron (also known as nerve cell) is an electrically excitable cell that takes up, processes and transmits information through electrical and chemical signals. It is one of the basic elements of the nervous system. In order that a human being can react to his environment, neurons transport stimuli.
