Remember that amino acids are held together by a peptide bond! This is an image from our protein synthesis video! We go over the steps of transcription and translation and the roles that ribosomes, DNA, and RNA play. We also compare and contrast RNA and DNA and explain the three different types of RNA. Come learn and laugh with the zany Amoeba Sisters! https://www.youtube.com/watch?v=h5mJbP23Buo
The primary structure refers to amino acid linear sequence of the polypeptide chain. The primary structure is held together by covalent bonds such as peptide bonds. The primary structure of a protein is determined by the gene corresponding to the protein. A specific sequence of nucleotides in DNA is transcribed into mRNA, which is read by the ribosome in a process called translation.
▶ Protein Synthesis Animation Video - 2:25 tRNA is joined to the mRNA by a peptide bond. A tRNA moved into the Asite where the codons match the mRNA the Ribosome shifts down by one codon at a time and new amino acids are added one at a time. It cuts off when a stop codon moves into the A site on the mRNA. The mRNA & the amino acid/protein are both released by the ribosome. p-site, A (acceptor) site & E site =Exit
