This video discusses the process of protein synthesis, which involves the transcription of genes into mRNA and the translation of that mRNA into proteins. The mRNA is processed in the nucleus and then transported to ribosomes in the cytoplasm, where it is used as a template to synthesize proteins.

  • 00:00:00 This video discusses the process of protein translation, transcription, and translation. The nucleus of a cell contains the genome, which is divided into 23 pairs of chromosomes. Each chromosome is made up of chromatin, which is a long strand of DNA. Sections of the DNA are called genes, and some of these genes have instructions to build proteins. When a gene is activated, an enzyme called adn polymerase binds to the initial segment of the gene and moves it along the DNA. This creates a strand of mRNA (a type of messenger RNA) from bases that are located in the nucleus. The mRNA's code determines the order in which the free bases are added to the messenger RNA. This process is called transcription. Before mRNA can be used as a plan for protein synthesis, it must be processed. This involves removing sections and joining them together. Then air is drawn out of the nucleus and finds factories called ribosomes. The ribosome attaches to the mRNA messenger and reads the code of this strand to create a chain of amino acids in the protein. In humans, there are 20 different types of proteins composed of 20 different types of amino acids. These molecules are transported across the cell membrane by transport proteins and deliver the amino acids to the ribosomes. The
