Translation etc

This is the next phase: translation of the mRNA into a protein sequence. We just began this briefly today. The glowing pig and tobacco plant are there for a reason. What does it tell you that you can express a firefly gene in a plant, or a jellyfish gene in a pig?

This is an electrophoresis gel showing some DNA we synthesized last year by PCR (Polymerase Chain Reaction). See the blog for more details.

Gel Electrophoresis

Once DNA is cut into smaller pieces, how do you know if you have cut them? How do you know if the pieces are the size you expect? The answer was "gel electrophoresis," which is a way to separate and identify DNA sequences based on size.

Protein blog

As I said earlier, a common theme in biology is how large "macromolecules" from subunits, usually known as monomers.
Proteins are arguably the most important and, inarguably, the most diverse of all the macromolecules.
Each protein begins as a long strand of hundreds (or thousands) of amino acids. Since there are 20 different amino acids commonly used, 100 amino acids would have 20100 possible sequences.
In practice, you won't see all possible ones and they are not randomly put together. Instead, the information in the DNA is used to specify what sequence is made (through a process we will learn about).
These chains then fold into complex structures you have seen.
