Today in Biology we had a late arrival which meant that we had less time to learn about DNA and RNA.

Some Notes that we took in class were

Transcription (RNA Sythesis)

One strand of DNA serves as a template for synthesis of mRNA
Occurs in the nucleus
RNA polymerase joins RNA nucleotides

Then we watched a video and from the video we learned that

The first codon is always AUG
Amino acids form together to form a peptide bond
tRNA looks for another amino Acid
If you link a bunch of amino acids together then you form a protien
Ribosomes make protien

More Notes

Translation (mRNA to Protien)

mRNA attaches to a ribosome
Each tRNA carries one amino acid
Anticodon on t RNA matches with a codon on mRNA
Amino Acids bond together to forn a polypeptide chain
Long polypeptide chains make a protien

Other Notes

Anticodon-series of three bases found on tRNA
Codon-series of three bases found on mRNA

Every codon codes for 1 0f 20 amino acids
