One can think of a Hydrogen bond like weak magnets sticking together, easily separated but will go right back together. Remember that DNA is inside the nucleus of the cell.Įach “step” or “rung” of the DNA ladder is made of a Hydrogen bond connection between two of the Nucleotide bases, thereby forming a “Base Pair”. The sides of the ladder are a “backbone” or “chain” of “Nucleotides” or “Bases” that are thankfully nicknamed by a single letter of A, C, T, or G. It looks much like a ladder with rungs (steps) that someone twisted into a long spiral. Picture Used: “Peptide Syn” by Boumphreyfr Available at under Creative Commons 3.DNA is a double-sided helix of encoded information that we inherit from our parents. Now that you are done with this video you should check out the next video in the Genetics section which covers Epigenetics, Histone Modification, Prader-Willi & Angelman Syndrome. Translation begins at the start codon (AUG) and ends at a stop codon. The tRNA, which carries the amino acid, has a complimentary anti-codon which recognizes the codon. Each amino acid is coded for by a 3 nucleotide sequence called a codon. Translation is the process by which a RNA sequence is converted into a set of amino acids (AKA a protein). This splicing can be carried out multiple different ways creating different proteins from a single gene. The splicesome also removes introns and joins exons. It is a AAUAAA sequence that is added without following a complementary DNA sequence and helps prevent degradation of the RNA. A 5’ Cap of a modified guanine is added to the end of the RNA to help the ribosome recognize the RNA. Post-Transcriptional Modification (RNA Processing) is the process of converting immature RNA to mature RNA that is ready to be translated. In Eukaryotes RNA Pol I makes Ribosomal RNA (rRNA), II makes Messenger RNA (mRNA) & III makes tRNA.
