In vivo dna binding pattern of the polycomb Txn factor 1. What are the genes towhich it binds? 2. how does it affect theserenes? 3. What determines where itBinds??
A female geneticist has difficulty characterizing flies by their eye color because she herself is red-green colorblind(an X-linked recessive phenotype). She has one sister(colorblind) and one brother(not colorblind)
Question 1 You have two pure-breeding colony of mice. Colony I mice have black fur and long tails, Colony II mice have golden fur and short tails You cross mice from each of these colonies
Below is an electron micrograph of a single gene being transcribed. The DNA strand runs horizontally with RNa transcripts extending vertically outward Image removed due to copyright reasons a)Draw an arrow indicating the direction that the RNA polymerases are
