you want to use crispr/cas9 to model a deletion mutation commonly found in cancer cells. suppose you design two sgrnas to this region of the genome. if cas9 cuts dna at 2 loci, what is the approximate size of the dna fragment expected to be deleted?

You have a solution that contains phospholipid vesicles in a test tube. these vesicles have phospholipid bilayers, but do not contain any membrane transporters. you add a number of different molecules to the solution, and wait a period of time for them to equilibrate. if you could measure the concentration of each molecule, for which of the following would you expect to measure equal concentrations inside and outside of the vesicles? assume for this question that the overall osmolarity inside and outside the vesicles is the same (that is, there is no appreciable diffusion of water across the membrane). (select two answers) an amino acid with a hydrophobic side-chain a small non-polar molecule a negatively charged ion a small polar molecule a small lipid hormone

Which codon is the code for the amino acid histidine (his)?
