genetic disease that affects the shape and functionality of red blood cells. It is caused by a mutation in the DNA of the protein‚ hemoglobin‚ specifically in the beta chain. There are 531 base pairs in this DNA strand. Substitution or point mutation occurs‚ causing “GAG” to become “GTG”. This results in valine being created instead of glutamate. The mutation causes the hemoglobin to cling together in low oxygen levels and the red blood cell changes shape‚ preventing it from carrying as much oxygen. The

Question Sheet B Sharon Jackson 1. The septum separates the heart into a right and left side. If there was a hole in the septum there would be a mix of oxygen right blood and oxygen poor blood and some oxygen right blood can enter the lungs instead of the body. 2. Capillaries exchange materials with the cells of the body there veins return blood to the heart and arteries take blood away from the heart 3. The SA node‚ or sinoatrial node initiates the heartbeat and automatically sends out a signal

Cari’s Story How could an infection in Cari’s nasal passages and pharynx spread into her sinuses?

Chapter 5 The skin is composed of two distinct regions‚ the epidermis and the dermis. These two areas are firmly attached to one another along a wavy borderline. The epidermis (epi = upon) composed of epithelial cells‚ and is the outermost protective shield of the body. Epidermis - Structurally‚ the epidermis is a thick keratinued stratified squamous epithelium consisting of four distinct cell types and five distinct layers. Cells of the Epidermis - Cells populating the epidermis include: keratinocytes

while the plant (Rheo discolor) is subjected to 0.3 M glucose. When the frog and mammalian bloods are subjected to 0.1 % NaCl‚ an influx of water occurs: the cells swell‚ the integrity of their membranes is disrupted‚ allowing the escape of their hemoglobin in the process of hemolysis because the solution is hypotonic. When 0.7% NaCl was added to the bloods‚ there is no net influx or efflux of water because the solution is isotonic. When 0.16 M NaCl was added to the bloods‚ the cells lose their normal

Tetrapyrrole compounds: chlorophyll and heme groups By Erwin Lim 1. Tetrapyrrole compounds A tetrapyrrole compound is a chemical group that consists of four pyrroles that are joined together by covalent bonds‚ forming a porphyrin ring. They are naturally occurring pigments‚ which are used in many biological processes (Berg‚ 2009). The basic structure of a tetrapyrrole is as seen in Figure 1‚ while the basic structure of a pyrrole is as seen in Figure 2. Figure 1.Tetrapyrrole Compound (Berg
