    for all our cells. Proteins main function is to help in tissue repair and growth. There are three different types of proteins. Fibrous proteins help in forming muscle tissues‚ tendons‚ bones‚ and connective tissue and some examples of these are Actin‚ Coronin‚ Elastin‚ and Myosin. Globular proteins help in regulating‚ catalyzing‚ and transporting. Some examples of globular proteins are Albumins‚ Ependymin‚ Fibrin‚ and Thrombin just to name a few.

    sub-units. The microtube holds all organelles in place so without this the organelles will collide with each other or float around randomly. The microtubules also act as tracks for the organelles to move. Microfilaments- are long threads of the protein actin which wrap around each other like ropes. Microfilaments help in the movement of cells‚ especially white blood cells and muscle cells. Intermediate Filaments- are rods that anchor the nucleus and some other organelles to hold their places inside the

    Week #1 -autotrophs are organisms that harvest light or chemical energy in organic compounds. They self nutrition -heterotrophs are organisms that get complex nutrients from the environment (by eating other organisms) -Fungi are heterotrophs or predators because they are parasitic. Bread mold secretes digestive enzymes to enter the membrane. Same as foot fungus‚ it extends hyphae (fungal branches) into the cells to absorbs nutrients -One fungus makes traps for nematode worms while another fungus

    nonsense mutations on this gene. Daniel et al. proposed that missense mutations on acting-binding domain (ABD) led to increase of actin-filamin compound in cytoplasm‚ the amount of which was correlated with phenotype severity of Larsen syndrome (Daniel et al.‚ 2012). And Sawyer et al. found that missense mutations in ABD could increase the affinity between FLNB and actin. These findings might explain difference between phenotypes of Larsen syndrome and those of SCT. The contradictions in phenotypes

    The Hair Follicle Stem Cell Niche and the Function of the Rac1 protein within the niche. Abstract: An adult stem cell’s niche is responsible for the preservation of the stem cell’s undifferentiated state through either intrinsic or extrinsic expression of specific proteins (Scadden‚ 2006). Situated in the bulge of the hair follicle‚ hair follicle stem cells (HFSC) are quiescent in nature and are responsible for not only its self renewal but also in the production of rapidly proliferating cells
