week 1 Walden 6501 advanced
pathophysiology questions with
solutions 2024
acrocentric - answer refers to the terminal location of centromere on chromosomes 13,
14, 15, 21, and 22
allelic heterogeneity - answer the situation in which multiple alleles at a single locus can
produce one or more disease phenotypes.
amorphic - answer refers ro mutations that cause a complete loss of function for the
respective gene, and therefore yield the same phenotype as a complete gene deletion.
aneuploidy - answer a general term used to denote any unbalanced chromosome
complement
antimorphic - answer refers to mutations that when present in heterozygous form
opposite a nonmutant allele will result in a phenotype similar to homozygous for loss of
function alleles.
ascertainment bias - answerthe situation in which individuals or families in a genetic
study are not representative of the general population because of the way in which they
are identified
autosomal - answerlocated on chromosomes 1-22 rather than x or y
CpG island - answera segment of DNA that contains a relatively high density of 5' - CG-
3' dinucleotides. Such segments are frequently unmethylated and located close to
ubiquitously expressed genes.
dictyotene - answerthe end of prophase during female meiosis I in which fetal oocytes
are arrested prior to ovulation.
dominant - answera pattern of inheritance or mechanism of gene action in which the
effects of a variant allele can be observed in the presence of a nonmutant allele.
dominant negative - answera type of pathophysiologic mechanism that occurs when a
mutant allele interferes with the normal function of the nonmutant gene product.
