The central dogma of biology describes the flow of genetic information from DNA to RNA to protein. DNA provides the genetic code or blueprint that is transcribed into messenger RNA (mRNA), which is then translated into proteins. Specifically, the document discusses that DNA is transcribed into mRNA, which is then translated into proteins through codons on the mRNA that each represent an amino acid, with 64 possible codons to code for the 20 amino acids.

2. The flow of genetic information
from DNA to RNA to protein
Initially, the central dogma of biology was simply thought
of as
DNA  mRNA protein

4. What do all those nitrogenous
bases mean?
 On the RNA
strand, each bracket
contains 3
nucleotides.
 3 nucleotides are
called a codon, each
codon represents an
amino acid.
 There are 64 (43)
possible code words
which is more than
enough to code for
the 20 amino acids

5. Now it’s your turn..
 You should be able to use the notes you took
for homework to complete the questions up
through the elongation stage of translation.
 Remember: There are lots of resources on the
