Question
Chapter 21, Problem 13P
Summary Introduction
To explain: HoxA3 and HoxD3 genes are nearly equivalent yet they play distinct roles in the development of mouse.
Concept introduction: Hox genes belong to the Homeobox family of genes which play a crucial role in the development of organisms and several genes of the homeobox genes are conserved through evolution. HoxA3 is expressed in the pharynx, colon, ovary and many more. HoxD3 is expressed in the ovary, genital fat pad and many more. Cis- regulatory sequences or elements are non-coding regions present in the DNA and control the transcription of neighboring coding-regions present in DNA sequences.
Summary Introduction
To explain: The reason why the genes when transplaced could not perform their normal function in a new location.

One of the ways for a cell to generate ATP is through the oxidative phosphorylation. In oxidative phosphorylation 3 ATP are produced from every one NADH molecule. In respiration, every glucose molecule produces 10 NADH molecules. If a cell is growing on 5 glucose molecules, how much ATP can be produced using oxidative phosphorylation/aerobic respiration?

As will be discussed in class, there are a number of non-scientific issues involved or implicated in rewilding, all ultimately affecting the public acceptability of rewilding. Although these issues are important – indeed, critical – in this assignment you should focus on the biological science issues and questions. Details: You must enumerate at least two pros and at least two cons. Your answer should be no more than 500 well-chosen words, excluding references.
