Class Summary - Today we talked about protein synthesis. Proteins are needed for essentially every process that the body does. The problem is that the information to make each protein is stuck in the nucleus as genes on the DNA. This is where transcription comes into play. During transcription, mRNA assembles using complementary nucleotides on DNA that has been unzipped at a specific gene. RNA replaces thymine with uracil. Once the mRNA has a complementary chain, it leaves the nucleus with the code for a specific protein. Translation occurs at the ribosomes (rRNA and protein). Three nucleotide combinations on mRNA are called a codon. tRNA brings the complementary nucleotides as 'anticodons.' These anticodons carry an amino acid. The amino acids combine to make proteins. We then watched a 20 minute video on this concept.
