gene one polypeptide lets us just know that.
Now we will take a very brief look at transcription.
In a future lecture, we will dig into it much
deeper and then we will take a quick look
at translation. The good news here is that
we have only one enzyme involved in transcription.
It is called RNA polymerase. It does very
similar thing to what we saw DNA polymerase
doing, but it adds RNA nucleotides to a growing
chain and we don't need to know about all
these apparatus because the whole DNA
strand will fit into this. We open up a tiny
window and a make a piece of RNA.
Then we have our coding strand. The coding
strand contains the genetic code and the template
strand is the strand that is going to be read
to make a complimentary strand too. The coding
strand matches the sequence of the messenger
RNA. The messenger RNA can then leave and
it will then move on to be translated into
proteins and that happens in the process of
translation. Translation involves ribosomes.
Some of these ribosomes are bound and some
of them are not. The ribosome is going to
assemble our messenger RNA in order to make
a polypeptide chain. Now we are literally
translating the message on the messenger RNA
into an amino acid sequence. The molecules
that are going to come into play there are our
transfer RNAs. Transfer RNAs or translational
RNAs come in and bring the amino acids
to the growing polypeptide chain inside the
ribosome. As the chain grows and gets to the
end of the gene on the messenger RNA, all
of this will fall apart and we have a translated
code, it is translated into a protein or a
polypeptide chain. That brings us to the idea
that things could
