Document Summary
Main question how much of it is genetics and how much of it is the result of experience: based on the premise that genes and environment combine in an additive fashion, rather than through an interactive process. Chordates: animals with nerve cords running along their backs, 450 million years ago. Vertebrates: animals with spinal boned that protect their dorsal nerve chords, 425 million years ago, primitive bony fish. Transcription and translation conversion of dna code into a protein. Chromosome tightly wound dna wrapped around proteins (histones) Dna (transcription) mrna (based on unwound dna) mrna (moves into cytoplasm) Interacts with ribosomes: ribosomes translate mrna into string amino acids, amino acid chain will form the protein. Epigenetics changes in phenotype caused by any means other than changes in underlying. Dna: histone remodelling, affects coiling of dna, effect on transcription and translation, dna methylation, added methyl group to cytosine base, affects protein synthesis.
