Protein Synthesis
Two phases of protein synthesis are transcription and translation. Transcription involves the transfer of information from a DNA gene's base sequence of an mRNA molecule. Translation is when the language of nucleus acids is translated into the language of proteins. DNA has a very important role throughout protein synthesis. DNA serves as the master blueprint for protein synthesis. It does not dictate the structures of lipids cans cabohydrates. It only focuses on the structure of protein molecules including the enzymes that catalyze the synthesis of all biological molecules. Transfer RNA, ribosomal RNA, and messenger RNA, all are formed on the DNA in the nucleus, similar to DNA replication. Ribosomal RNA and tRNA act together to "translate" messages that are carried by mRNA. Triplets are specific sequences of three bases that specify a particular amino acid. The sequence of triplets from a sentence. The corresponding three-base sequence on mRNA is called a codon. There are 64 possible codons. Three of these are stop signs. They call for termination of a polypeptide. An anticodon is found in a tRNA . It is a three-base sequence complementary to the mRNA codon calling for the amino acid carried by the particular tRNA. They form hydrogen bonds with complementary codons. A tRNA is the link between the language of nucleic acids and the language if proteins.
