Breast Cancer Research Biology 1010 Breast Cancer is a dynamic and devastating disease that kills and affects millions of people. Some of the newest research is fascinating. There have been discoveries from what may potentially cause breast cancer‚ to preventions of breast cancer. To understand the research behind breast cancer and why it is so important you must first understand what breast cancer is. Breast cancer is a malignant tumor that starts from cells of the breast. A malignant tumor

Breast Cancer Garry B. Neal Bio. 127 6/22/13 Introduction Breast Cancer has been around since the beginning of times. It is noted that the earliest recordings were date back to Ancient Greece and Egypt around the year 460 B.C.‚ when Hippocrates depicted it as humorol disease. He proposed the Human Body was made up of four humors (phlegm‚ black bile‚ yellow bile‚ and blood). He then premised that cancer was caused due to the overabundance of black bile. This idea of breast cancer was believed

disordered skin pigmentation. The tumors would be able to cause bumps under the skin‚ colored spots‚ skeletal problems‚ and other neurological problems. Neurofibromatosis is also an autosomal dominant disorder‚ which means that only one copy of the affected gene is needed for the disorder to develop. In this case if there were only one parent who has neurofibromatosis‚ then their child has a 50% chance of getting the disorder. The disorder affects males and females equally. There are two types of neurofibromatosis

The Cell Cycle A eukaryotic cell cannot divide into two‚ the two into four‚ etc. unless two processes alternate: doubling of its genome (DNA) in S phase (synthesis phase) of the cell cycle; halving of that genome during mitosis (M phase). The period between M and S is called G1; that between S and M is G2. So‚ the cell cycle consists of: G1 = growth and preparation of the chromosomes for replication; S = synthesis of DNA [see DNA Replication] and duplication of the centrosome; G2

public health implications What is epigenetics? Is the study of heritable and potentially reversible gene-expression changes that do not involve structural alterations in the DNA sequence‚ such as mutations. Is emerging as one of the most dynamic and vibrant biomedical areas .

Genetic diseases transmitted only by a mother to both sons and daughters result from mitochondrial genes. Q7. Within a species‚ when a gene has multiple alleles‚ a single individual may carry 2 alleles. Q8. In humans the only cytoplasmic organelles besides nuclei that contain DNA are the mitochondria. Q9.

Animal rights and animal welfare fall at different points on a continuum that runs from animal liberation at one end to animal exploitation at the other. The animal rights viewpoint can be defined as the belief that humans do not have the right to use animals for their own gainin the laboratory‚ on the farm‚ in entertainment or in the wild. The degree to which humans may benefit from any use of nonhuman animals is irrelevant to determine how animals should be treated. The animal welfare viewpoint
