    Study Notes

    The Central Dogma of Molecular Biology refers to the process of genetic information flow during gene expression, which goes from DNA to RNA to Protein. Francis Crick proposed the Central Dogma, which involves transcription, where DNA is used to synthesize RNA, and translation, where RNA is used to synthesize proteins. The process of transcription involves Initiation, Elongation, and Termination. RNA polymerase interacts with DNA sequences during the transcription process, and an RNA-DNA hybrid molecule is produced as the DNA strand is copied into RNA. Transfer RNA (tRNA) acts as a translator molecule that recognizes both nucleic acids (mRNA) and amino acids, connecting them during translation (protein synthesis). The genetic code is based on codons, which are groups of 3 bases coding for an amino acid in the genetic code. The 'Central Dogma' involves transcription and translation, where DNA makes RNA, which then makes proteins. There are 64 codons in the genetic code, with AUG being the initiation codon, and UAA, UAG, and UGA being the termination (stop) codons in the genetic code.
