DNA TRANSCRIPTION
DNA transcription is the process of which genetic information is copied from DNA to RNA.
RNA, though similar, is different from DNA. While DNA is used for genetic information storage in multicellular organisms, RNA is used transfer the genetic code needed for the creation of specific proteins from the nucleus to the ribosomes.
In this process, strings of DNA are read in sets of three and then deciphered into certain proteins. This is best read and understood by humans in the form of a codon chart. (Pictured below.) This chart shows the interpretation of the DNA strands, as the certain patterns and sequences of nucleotides create specific proteins.
During transcription, the nucleotide Thymine is replaced by Uracil, which also bonds with the nucleotide Adenine. (Displayed right).
This makes mRNA, also known as "messenger DNA".
