1. Heparin is a polyanion that inhibits RNA transcription in vitro by binding directly to bacterial RNA polymerase (RNAP). If heparin interferes with the ability of the polymerase to bind DNA in a non-specific fashion, what subunit of RNAP is the heparin binding to? 2. The 5′ end of the […]

In the imaginary species, the white-lipped tree wolf, male pups are born at twice the size of female pups. Males require twice the food of females to reach sexual maturity. What is the expected sex ratio at birth? a)twice as many males as females b) twice as many females as […]

The Sanger dideoxy method for determining DNA sequence is limited in that a stretch of only 1000 or fewer bases can be analyzed in one reaction. Suppose you wish to sequence a newly isolated double-strand DNA tumor virus that contains 5000 base pairs. You decide to use the Sanger method […]

Explain how bacteria reproduce. Which factor do they rely on to increase genetic variation? Discuss the advantage(s) and disadvantage(s) of asexual reproduction in the light of evolution. Explain how meiosis and sexual reproduction generate biodiversity. Discuss the advantage(s) and disadvantage(s) of sexual reproduction in the light of evolution. Loss of […]
