Proteins are large complex molecules that play an important role in the structwe functim and regulation of tissues and organs in the body Proteins are a part of most body processes They help build the body and aid in repair O Transcription is the process of turning Translation is the process of building Transcription happens in the nucleus The process of protein synthesis uses the information from the nucleotide sequence of DNA to create the amino acid sequence of a protein This process involves many organelles and molecules including RNA creates mRNA thymine replaced with uracil DNA Translation made of adenine happens in the ribosome creates protein cytosine guanine and A codon is a group of three bases on a strand of messenger RNA mRNA that codes for a specific amino acid Each transfer RNA tRNA molecule has an amino acid attached and matches up to a specific codon of mRNA As the tRNA pairs with the codons on the mRNA the amino acids form peptide bonds making a protein chain strands DNA Proteins made of adenine into MRNA using MRNA Transport ytosine guanine and RN happens in the rough endoplasmic reticulum and the Golgi apparatus strand Modification happens in the Golg apparatus chemical groups added or removed affect protein function Prokaryote Cells Prokaryotic cells do not have a nucleus but still need to synthesize proteins Transcription and Cranslation occur in the of prokaryotes
