USABO EXAM QUESTIONS AND ANSWERS Eukaryote - ANS An organism whose cells contain complex structures enclosed within membranes. The defining membrane bound structure that sets them apart from prokaryotic cells is the nucleus or nuclear envelope within which the genetic material is carried. All large complex species are eukaryotes, including animals, plants and fungi. Euchromatin - ANS This shows as pale areas in the nucleus under electro magnification. It is a less densely packed for...

USMLE Biochemistry Exam Questions with Correct Answers Heterochromatin - ANSWER Highly Condensed DNA Transcriptionally inactive Ex. Barr bodies (inactivated X chromosomes) Euchromatin - ANSWER Less condensed DNA Transcriptionally active DNA Methylation - ANSWER Occurs at *CpG Islands* to repress transcription 'CpG Methylation Makes DNA MUTE' Template strand *cytosine* and *adenine* are methylated, which allow mismatch repair enzymes to distingu...

Overall organizational structure of the human chromosome correct answers normally contain a single, immensely long DNA double helix; to avoid tangling and to manage the long chain efficiently they are complexed with various proteins and sometimes noncoding RNAs to form chromatin that undergoes different levels of coiling and compaction Chromatin correct answers the structure of DNA complexes with proteins that are coiled and compacted - the double helix is wound around positively charged his...
