The Klenow fragment of E. coli DNA polymerase I is used: correct answersto label DNA probes by random primer labeling. What is a solution hybridization method for the detection of nucleic acid:protein interactions? correct answersgel mobility shift assay _____ involves mixing a labeled oligonucleotide with a protein extract to see if a specific interaction occurs, visible with an apparent increase in molecular size on a gel due to the protein:nucleic acid interaction. correct answersGel mo...

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...

BIO 105 FINAL EXAM QUESTIONS AND ANSWERS ALREADY PASSED where in the cell cycle is DNA transcription and RNA translation occurring? interphase only Where in the cell cycle is DNA replication occurring? S-phase genes are carried on ___ chromosomes key concept of base pairing hydrogen bond each A with a T hydrogen bond each C with a G about DNA... -the two strands are anti-parallel (opposite polarity) -hydrophobic bases stack in center (hydrophobic effect maximized) -2 strands o...

Describe the process of transcription. What are the starting molecules and the end products? - Transcription is the manufacture of a strand of RNA complementary to a strand of DNA. In initiation, RNA polymerase binds to a promoter region on the DNA strand. RNA synthesis occurs during the elongation phase as RNA nucleotides are added to the growing RNA polynucleotide. When the RNA polymerase reaches the terminator region of the gene, elongation stops and the polymerase and new RNA molecule d...
