In Bio 202 one way we’ve learned to examine a cell is by taking advantage of the differences within the chemical reactivity of the molecules located within (Lab Manual‚ Chp. 5). Major biological molecules such as Polysaccharides

Lauryn wagner Bio extra credit Neurofibromatosis type one is a genetic disorder the causes noncancerous (benign) tumors as well as skin pigments called cafe-au-lait spots .NF1 is caused by mutations in a gene called NF1‚ which can be found on chromosome 17. This gene regulates the production of a protein known as neurofibromin‚ which is thought to function as a tumor suppressor.In about half of individuals with NF1 the disorder results in spontaneous mutation of the gene that occur for unknown

Father. People with light eyes tend to carry recessive alleles of the major gene and people with dark eyes tend to carry the dominant alleles. Genes are located on rodlike structures called chromosomes that are found in the nucleus of every cell in the body. Each gene is assigned a specific position on a chromosome as genes provide the instructions for making proteins‚ and proteins determine the structure and function of function of each cell in the body‚ it follows

An autosomal disorder is when the defected gene is carried on a chromosome other than one of the sex chromosomes. Bloom’s Syndrome happens to be an autosomal recessive disorder‚ which causes this disorder

symptoms of alcoholism are anxiety and depression. This relates to what we are doing in class because we are speaking about genes and genetics. We’re also learning about genetic disorders which happen when one person is missing a chromosome or has an extra chromosome. Examples can be Down syndrome or Turner Syndrome. This also relates to punnett squares. In punnett squares you find the probability of characteristics and you can use one to find out the probability of a person developing alcoholism
