UNE Medical Biochemistry Midterm Review Already Graded A A family presents for genetic counseling. The couple has two female children who are alive and well; however, their infant son recently died in the nursery with severe hemolysis (lysis of red blood cells) and jaundice. The wife recalls she lost a brother in infancy with severe hemolysis, induced after a viral infection. The physician suspects a glucose-6-phosphate dehydrogenase deficiency, this would result in a deficiency in which of the...

This summary contains the lecture notes and additional information that eleborates statements from the lectures. Since there is no book assigned to this course, the information is mostly added by online research. The document is seperated for each subject and provides additional information on the most important points.

Give two examples of how eukaryotic organisms derive benefits from regulating gene expression - 1) Rabbits change from brown to white due to a response to environmental changes 2) larval to adult is totally different b/c of different proteins during life changes gene expression control is used in multicellular organisms to. . . - define tissues and cells w/ specific functions w/in organism What is the order of regulation of gene expression - transcription, RNA processing, translation, post...

activators - TFs that increase the levels of transcription initiation Adaptive mutations - evolutionary change and adaptation to new environments, stressful conditions darwins birbs AP - activator proteins ARE - AP2 response elements Base analogs (chem induced - 5-bromouracil resembles thymine, except that it has bromine atom in place of methyl on 5' C base excision repair (BER) - repairs damaged base by using AP endonuclease to cleave damage on 5' side and DNA polymerase add new base...

MCB4304 Exam Questions & Answers 2024/2025 Why does the estimated number of protein coding genes in prokaryotes correlate well with genome size? - ANSWERSBecause most genes are coding regions and prokaryotic DNA do not have introns Why does the estimated number of protein coding genes in eukaryotes correlate poorly with genome size? What is the estimated number of genes in humans? - ANSWERSBecause Euks have introns and some of our genes are regulatory sequences and non-coding DNA. many g...
