Summary Introduction

To propose:

A possible explanation for the observation that out of 1000 pairs of identical males and 1000 pairs of identical females, on the basis of three measure, the two male twins of a pair tended to be more alike in their scores than were two female twins of a pair.

Introduction:

Monozygotic twins are identical twins that are derived from a single egg fertilized with single sperm, forming a zygote. The zygote later divides into two resulting in genetically identical twins. Caroline Loat and her colleagues examined abilities such as social, cognitive and behavioral in identical pairs of female and male twins.

Summary Introduction

To determine:

The location of genes that influence pro-social behavior, peer problems and verbal ability.

Introduction:

The female carries two X chromosomes whereas male carry one X chromosome. Thus, the presence of two X chromosomes result in formation of double amount of protein which may result in diseased condition. Thus, the inactivation of one X chromosome in female is necessary. This phenomena is known as dosage compensation.

If left untreated, most HIV-infected individuals will develop AIDS. Current treatments are focused on highlyactive antiretroviral therapy (HAART). HAART usually consists of an orally delivered drug cocktail containingtwo different reverse transcriptase inhibitors and one other drug, such as a protease inhibitor. Question: Develop a pharmacokinetic model of HAART treatment. Consider all 3 drugs. Make sure to include adiagram that illustrates your thinking, state all assumptions, and define your variables. Whatparameters would you need to know to find the concentration of drug in the plasma? In the T cells?(You do not need to write out or solve any equations.)
