Scientists at the National Human Genome Research Institute
(NHGRI) at the National Institutes of Health (NIH) have for
the first time precisely identified a gene abnormality that
causes some cases of Parkinson's disease. The gene spells
out instructions for a protein called alpha synuclein. In
the abnormal version of the gene, the researchers found a
mutation in a single base pair - one incorrect letter in
the string of more than 400 that compose the instructions
for making the protein. Because the normal gene plays a
role in the function of nerve cells, the finding gives
researchers a powerful new tool for understanding cellular
abnormalities in Parkinson's disease and demonstrates a
connection between Parkinson's disease research and
research into other neurological disorders, such as
Alzheimer's disease.

Explain in terms of gene product function how a mutant allele can be dominant? recessive?
A number of plant species have a recessive allele for albinism; homozygous albino (white) individuals are unable to synthesize chlorophyll. If a tobacco plant heterozygous for albinism is allowed to self-pollinate and 500 seeds germinate: a)how many offspring will be the same genotype as the parent? b)how many seedlings would you expect to be white?
Cystic fibrosis (CF) occurs with a frequency of about 1/2500 Caucasian newborns and is inherited as an autosomal recessive. A woman had an older sister die from complications of this disease. CF is not present among relatives of her husband. Both the woman and her husband have normal phenotypes. What is the chance this couple will have a CF child
what are the genetical reasons behind obesity?
How will you differentiate alleles of a gene in the double strand of DNA?
Explain steps involved in transcription?
Flower position, stem length, and seed shape were three traits that were studied by Mendel. Each is controlled by an independently assorting gene. If a plant that is heterozygous for all three traits was allowed to self- fertilize, what proportion of the offspring would be expected to show all three dominant phenotypes?
what is Avian flu threat? what are its symptoms?
Suppose you are heterozygous for a mutant beta-thalassemia allele. If the frequency of beta-thalassemia is 1/1600 persons, what is the probabilty that your prospective spouse is heterozygous for a mutant beta-thalassemia allele?
