Document Summary
Dna stores the information, rna transfers the info to proteins, which do the work = the central dogma of molecular bio. Cant see cells with eye, but only in microscope (10-100 microns) )animal plant cells (which are bigger); each cell has organelles. Dna is in the nucleus, chloroplasts, and mitochondrion. The nucleus: where most info is; wall is made of skin (nuclear envelope) , and the nucleolus inside (does not perform important functions) Nuclear pores on the envelope allow molecules to move into and out of the nucleus. Proteins package up the dna so that when it is needed they package out. One side of ladder has sugars and other has phosphates; called sugar phosphate backbone. 5 carbons and 1 phosphate group make acid of dna. 4 base c a g t (nucleic acid bases); actg, adenine, thymine, guanine, cytocine; other side is gatc. 3 hyd bonds hold gc together, 2 hold at together.
