Question
Chapter 9, Problem 8WIO
Summary Introduction
To determine:
Whether it is possible for a boy-girl pair of twins to be genetically identical.
Introduction:
The process of meiosis produces four genetically different haploid nuclei. This process produces egg cells in females and sperms in males. When the egg and sperm unite at fertilization, zygote forms. When mitosis follows, each daughter cell contains the same genetic material as the zygote. If an early embryo splits just a few hours or days after fertilization and the resulting split is complete, then it results in the formation of identical twins. If the split is incomplete, then conjoined twins develop.

✓ Details
Draw a protein that is embedded in a membrane (a transmembrane protein), label the lipid bilayer and the protein. Identify the areas of
the lipid bilayer that are hydrophobic and hydrophilic.
Draw a membrane with two transporters: a proton pump transporter that uses ATP to generate a proton gradient, and a second
transporter that moves glucose by secondary active transport (cartoon-like is ok). It will be important to show protons moving in the
correct direction, and that the transporter that is powered by secondary active transport is logically related to the proton pump.
drawing chemical structure of ATP. please draw in and label whats asked. Thank you.

Affected individuals show spots of abnormal skin pigmentation and non-cancerous tumors that can interfere with the nervous system and cause blindness. Some tumors can convert to a cancerous form. i The recessive form is a normal protein - in other words, no neurofibromatosis.moovi A typical pedigree for a family that carries neurofibromatosis is shown below. Note that carriers are not indicated with half-colored shapes in this chart. Use the letter "N" to indicate the dominant neurofibromatosis allele, and the letter "n" for the normal allele.
