3.2 Herbicide tolerance

As you discovered from Activity 1, herbicide tolerance is the trait most commonly incorporated into commercial GM plants. A crop can be made tolerant to herbicide by inserting a gene that causes plants to become unresponsive to the toxic chemical. Before considering how the genetic manipulation can be achieved, it is useful to understand a little about how herbicides act.

Many herbicides work by inhibiting a key plant enzyme necessary for growth (if you're not exactly sure what this mea

3.3.1 Dormancy in black and brown bears

The dormant state of bears differs from true hibernation in that the body temperature does not fall below 31–35° C and a major disturbance (such as an intruding biologist) can arouse them to full activity in a few minutes. Dormant bears do not eat, drink, urinate or defaecate, the heart rate drops from 50–60 beats min−1 to 8–12 beats min−1, and oxygen consumption is only 32% of that of actively foraging bears. Nonetheless, the rate of protein turnover, as mea

How internet and games affect the teenage mind: mini-lecture (UCL)
Lionel Bailly (UCL Psychoanalysis Unit) examines the effect new media (the internet, social networking and video games) has on the adolescent mind. According to Bailly, the virtual personas many teens create for themselves act as a warped mirror of their actual selves.

Introduction

In this course you will find out that the sensation of pain is caused by the release of a chemical called prostaglandin that stimulates the nerve endings and sends an electrical message to the brain. Inhibiting the formation of prostaglandin reduces pain and we will see, by looking at the specific shape of the molecules involved, how aspirin can so inhibit the formation of prostaglandin. To make the most of the material of this course you will need to use an organic molecular modelling kit su

1.1.6 Late-onset multifactorial disorders

It is becoming clear that many, if not most, of the common diseases that affect the Western world are multifactorial disorders with some inherited genetic component. Some of the genes that render individuals susceptible to diabetes, coronary heart disease, hypertension and many cancers, including breast cancer, have been identified and can be tested now for the presence of mutations. Multifactorial disorders present a real challenge for genetic medicine. For example, while it may be true that

Standard Form of a Linear Equation
This video clip describes how lines expressed in the standard form of a linear equation are commonly seen, especially when looking at and writing systems of linear equations. The standard form of a linear equation puts the x and y terms on the left hand side of the equation, and makes the coefficient of the x-term positive. While standard form is commonly, we sometimes rewrite a line in slope-intercept form in order to graph it. (1:13)
