Biology 1202B Lecture Notes - Lecture 14: Cytosine, Mitosis, Escherichia Coli
Document Summary
Most of dna is contained in the nucleus: dna in chloroplast or mitochondria is just for those organelles, dna in unless has a predominant role for all processes in the cell. Proteins called histones are wrapped around dna: important in transcription and epigenetic. Debate - does dna control everything : high school: dna is the master regulator of the cell, those genes dictate what"s going to happen in your cell. Metabolism = sum of reactions: metabolism interacts with proteins and rna. Rna can be functional w/o being translated into a protein. Central dogma - dna > rna > protein: not complete, not all rna turns into protein. Only coding genes get translated into proteins. Proteins can directly go and interact with dna. Proteins can"t go back to dna they can interact with dna. The only thing that has refuted this central dogma is the discovery of. Retroviruses: rna gets converted into dna in retroviruses.
