cell lab part III


DNA replication turning into 2 identical strands of DNA.




DNA molecule made out of a pipe cleaner.


DNA transcprition to mRNA.



The following pictures are a model of the process of mRNA translation to proteins.

In this picture the 2 ribosomal sub units come together with mRNA and tRNA-amino acid.














In this picture "The polypeptide will be transferred to the tRNA-amino acid."(Mader pg451)



In this picture "One tRNA is out going and another tRNA is incoming" (Mader pg 451)














In this picture the ribosome stops and releases the polypeptide. A protein molicule is made up of polypeptides.
