Ans: The flow of information starts with DNA, waiting in the nucleus of eukaryotic cells. A temporary copy is made whenever the cell wants to extract information; this copy is made of a less secure, less stable but similar molecule RNA.
The RNA copy is often altered by additions and subtraction before being sent to the cytoplasm for translation by ribosome. In this process tRNA bearing amino acid are evaluated for fit to the currently active codon of the ribosome.
If a match is made between tRNA and mRNA, the amino acid attached to the tRNA accepts the growing polypeptide chain, and the ribosome progresses along the mRNA until a nonsense stop codon brings the process to a halt.
Explanation: The DNA is a double helical, extremely stable molecule which is found in the nucleus of eukaryotic cells as chromosomes. It stores the genetic information which is passed on to the daughter cell everytime the cell divides. This genetic information is utilized by cells to make up proteins or polypeptides, but before that can happen, it is encoded in a transient not so stable copy called an RNA, by a process called transcription.
This RNA (mostly mRNA) serves as a template for ribosomes during the process of the translation. tRNA carrying an amino acid is a cloverleaf-like molecule. It enters the ribosome site and if there is a codon match, it transfers the amino acid to the growing peptide chain.
