One thing I learned in this 3-class lesson is about how proteins are made in the human body. The way proteins are made is, proteins are digested into the stomach and the proteins get broken down into little pieces called amino acids. The amino acids are then built and combined with other amino acids that then are the proteins to our body.
Proteins are molecules that are very important to the human body. Proteins are not only important to the body, but also to the cells in the human body. Proteins are the molecules that take out most of the work because they are what make us healthy. The body would not be able to survive without protein. Which means, having protein deficiency can give many side affects. Some side affect could be loss of memory, light headed, mentally retarded, getting skinnier, stomach and head ache, become very weak, etc. Our body creates the protein inside of us by breaking up the amino acids and rebuilding them back up into
One thing i learned in this 3-class lesson is about transcription and translation there is a molecule that races down on a DNA strand, unzipping it to create RNA. In the RNA copy it has the four letters A, G, C, and T. In the RNA copy it is a little different though, there is no T, instead its a U. When the RNA copy is complete it snakes away from the nucleus to the outer part of the cell. Then the ribosome attaches itself to the RNA copy to form a little factory and transfer molecules transfer the amino acid to the factory (ribosome) to make a protein chain which is all the amino acids that are being brought to the ribosome. The way an individual cell knows which specific proteins need to be made is through something called, the genetic code. The way a cell knows when proteins need to be made is a message that is sent to the DNA by hormones. The proteins are made specifically by codons which are 3 chemical bases that form amino acids and creates the proteins. Each cell can make a specific protein because the genetic material in the messenger RNA. It makes the transfer RNA get the corresponding amino acids and the amino acids fold up into protein.
