USABO QUESTIONS CORRECTLY ANSWERED 2024. Eukaryote - ANSWER An organism whose cells contain complex structures enclosed within membranes. The defining membrane bound structure thats sets them apart from prokaryotic cells is the nucleas or nuclear envelope within which the genetic material is carried. All species of large complex species are eukaryotes, including animals, plants and funghi. Euchromatin - ANSWER This shows as pale areas in the nucleas under electro magnification. It is a less ...

AP Biology Reading Guide Chapter 15 and 16: Regulation of Gene Expression & Development, Stem Cells and Cancer. Compare and contrast the lac operon and the trp operon. (Remember that compare means “to tell how they are similar,” and contrast means “to tell how they are different.”) Lac is inducible and trp operon is repressible. They both have the three components of an operon: an operator, promoter, and regulatory gene. They are different because the trp repressor is inactive alone ...

CPPS 403 Pre-Midterm Exam Questions with Correct Answers Each chromosome contains a single continuous DNA molecule and DNA bound to histone proteins are organized into subunits called nucleosomes. DNA bound around 8 histone proteins. Chromatin - Answer- DNA is condensed into chromatin, condensed into nucleosome. Chromatin fibers are units of DNA wrapped around histones. Chromatin condensed becomes chromatin loops of variable size and there is chromatin domains/topologically associati...
