My Dictionary 2

The Transfer of Genetic Information 
 
Transcription:  the information is copied as RNA nucleotide sequences 
 
Translation:  RNA molecules  in ribosomes then synthesize polypeptides 
 

Central Dogma:  DNA is transcribed to RNA; which is translated to form polypeptides


Events in Transcription 

RNA Primer:  molecules for DNA polymerase to use during DNA replication


Messenger RNA (mRNA):  molecules which carry genetic information from chromosomes to  ribosomes 

Ribosomal RNA (rRNA):  molecules which combine with ribosomal polypeptides to form ribosomes

Transfer RNA (tRNA):  molecules which deliver the correct sequence of amino acids to ribosomes based on the sequence of nucleotides in mRNA
