Typical definition of GeneticsThe study of genes, heredity, and genetic variation What is a gene?•Basic unit of heredity •Sequence of DNA that codes for a product (RNA or protein) and it's regulatory regions •Located on chromosomes What is an allele?One of two or more versions of a gene What is a genome?•The complete set of genetic material in a cell (including mitochondrial, chloroplast, plasmid DNA) •Includes genes as well as non-coding DNA regions Genes vs Traits/phenotypes•G...

Biology 1000 – Principles of Biology ( BioS 115 Core II: Genetics) Exam Study Guide Questions With Answers. Explain the concepts of penetrance and expressivity Penetrance is the percentage of cases in which a certain phenotype is expressed. There are two types: i. Complete Penetrance: when 100% is correlated to the genotype. So, all express the same thing. ii. Incomplete: this is when some are identical, and others are different. Penetrance= # with genotype showing phenotype x 100 # wit...

USLME Biochem - First Aid Exam Questions With Accurate Answers. Chromatin structure - answerDNA exists in condensed chromatin form in order to fit in nucleus Negatively charged DNA loops twice around positively charged histone octamer (2 sets of H2A, H2B, H3 and H4) to form nucleosome "bead" Octomer subunits consist primarily of lysine and arginine amino acids (positively charged).
