Cystic fibrosis resulting when a person has mutations in both of the body's copies of the cftr gene; Suggestion that the mutant cftr gene persists so widely because of a heterozygote advantage; Suggestion from Gerald B. Pier and colleagues at Harvard Medical School in Boston, Massachusetts that...
Cystic fibrosis is a genetic disease. People with CF haveinherited two copies of the defective CF gene -- one copy from each parent. Both parents must have at least one copy of the defective gene. People with only one copy of the defective CF gene are called carriers, but they do not ...
What gene is associated with chronic myeloid leukemia? What chromosome causes retinitis pigmentosa? Describe heredity What genetic mutation causes celiac disease? How do autosomal dominant diseases not die out? A disease only develops in individuals who are homozygous recessive for the gene responsible ...

Though they are more similar than different, vitamins D2 and D3 may affect gene expression differently, particularly with genes associated with immune function. Research suggests that vitamin D3 is more effective at regulating gene expression, helping stimulate the immune system to fight off bacteria...
What are the two main steps in going from a gene to a protein? On which segment of the human chromosome is an enzyme reverse transcriptase located? What is the branch of genetics that deals with the expression of genes by studying the DNA sequences of chromosomes?
Bacteria can evolve rapidly by acquiring new traits such as virulence, metabolic properties, and most importantly, antimicrobial resistance, through horizontal gene transfer (HGT). Multidrug resistance in bacteria, especially in Gram-negative organisms,
A gene is a set of instructions for making a molecule given through a set of nucleotides in a molecule of DNA or RNA, with most of the DNA existing on the 23 pairs of chromosomes in the nucleus of each human cell. The bases of the nucleotides—which are adenine, cytosine, guanine, ...
