Make sure to include the mode of transmission, symptoms, treatment of the disease and long-term prognosis

Calculate the size of your PCR products for a woman who is heterozygous for a 40-polyglutamine repeat disease allele (120 bases in length), and a 23-polyglutamine non-disease- allele repeat (69 bases in length).

1. Describe the structure of the skin and mucous membranes and the ways in which pathogens can invade the skin. Give examples of and describe a microbe that can reside on the skin but not cause harm and a microbe that can be pathogenic when on the skin.

2.
