BIOSC 0160 Lecture Notes - Lecture 1: Nuclear Dna, Genetic Marker, Transfection
Document Summary
Reading for lecture 2, due 1/11/18, pg 266-277. 13. 1 experiments revealed the function of dna as genetic material. 13. 1 experiment revealed the function of dna as genetic material. Dna was in the right place: dna was important component of the nucleus and chromosomes which were already known to carry genes. Dna was present in the right amounts: twice the amount of dna in somatic cells (body cells not specialized for reproduction) than in reproductive cells, matched expectation for diploid and haploid cells. Dna varied among species: cells from dif species stained with dye showed with varying intensities that dif species had dif amounts of nuclear dna. Some scientists didn"t believe dna was genetic material because such a unform structure couldnt relay all the functions of life. Eukaryotic cells can also be genetically transformed by dna: this is called transfection, can be demonstrated under genetic marker. 13. 2 dna has a structure that suits its function:
