Retrotransposons - Guides d'étude, Notes de cours & Résumés

T/F: DNA looping is important for RNA polymerase activity in the presence of enhancer elements. - answer-True T/F: Genome editing has been greatly facilitated by the adaptation of the bacterial CRISPR-Cas9 system. - answer-True T/F: Transposase is required for non-LTR retrotransposon movement. - answer-false-transposase is required for transposon movement. non-LTR retrotransposon movement requires reverse transcriptase T/F: LTR and non-LTR retrotransposons require reverse transcriptase ...

Evolutionary analysis ch. 2 question n answers graded A+ 2023Lamarck - correct answer in 1809 that all species are derived from gradual evolution. He guessed it was driven by the inheritance of acquired traits. Said simple life forms are spontaneously generated from nonliving matter. His ideas were popular until the 1930s Vestigial structure - correct answer remnant of a structure that may have had an important function in a species' ancestors, but has no clear function in the modern species...

BIO 235 - Final Exam Study Guide The Central Dogma of molecular biology states that, in cells, biological information _______. A. Can be transmitted either from DNA to RNA or from RNA to DNA B. Moves from DNA to RNA to protein C. Moves from protein to RNA to DNA D. Moves from DNA to RNA only if encoded by certain viruses E. Moves from protein to RNA only if encoded by certain viruses - B What is the exception to the Central Dogma rule? - RETROVIRUSES (process goes from RNA to DNA usin...

DNA sequencing and Genomes Exam Questions and Answers Latest Update Graded A+ Sanger sequencing development - Answers Developed in 1977 Fred Sanger •Called Sanger Sequencing - still used today Sanger sequencing - Answers DNA sequencing method based on selective incorporation of chain-terminating inhibitors (dideoxynucleotides) by DNA polymerase during in vitro DNA replication Dideoxynucleotides ddNTPs, and the Sanger sequencing reaction - Answers ddNTPs are chain terminating nucleotide bas...

BIO 320 Exam 2 Study Guide Solutions Gene - ANSWER-a unit of heredity that is transferred from a parent to offspring and is held to determine some characteristic of the offspring Genome - ANSWER-the complete set of genes or genetic material present in a cell or organism Introns - ANSWER-non-coding sections of the RNA that are spliced out before the RNA is translated into a protein Exons - ANSWER-coding sections of the RNA that will not be spliced out and will be present in mRNA Mature euk...

Bio Practice Exam 28 Questions with Verified Answers Why did DNA evolve to be the carrier of genetic information in cells as opposed to RNA? - CORRECT ANSWER the hydrogen at the 2' position in the deoxyribose of DNA makes it more stable than RNA In the mismatch repair process, enzyme complexes replace bases that were incorrectly inserted into the newly synthesized DNA strand. To function, they must be able to distinguish between the parent DNA strand and the new strand. How is this accomp...

primary epigenetic marks = sequence specific - intrinsic DNA sequence - sequence-specific TFs - noncoding RNA secondary epigenetic marks = sequence independent - readers of DNA methylation - noncoding RNA methylation in bacteria - methylation A or C to identify & degrade invading DNA & track mismatch methylation in bacteria functions - timing of DNA replication - partitioning nascent chromosomes to daughter cells - repair of DNA - timing of transposition & conjug...

Evolutionary Analysis Exam 1 Questions With Correct Answers What is evidence of microevolution? - answer-selective breeding (picking particular individuals with a desirable trait to reproduce...remember those running mice?) -direct observation of natural populations (mustard seeds that survived the drought) vestigial structure - answer-a useless or rudimentary version of a body part that has an important function in other, closely allied species (this just doesn't make sense with "specia...

BIO 235 - Final Exam Study Guide The Central Dogma of molecular biology states that, in cells, biological information _______. A. Can be transmitted either from DNA to RNA or from RNA to DNA B. Moves from DNA to RNA to protein C. Moves from protein to RNA to DNA D. Moves from DNA to RNA only if encoded by certain viruses E. Moves from protein to RNA only if encoded by certain viruses Ans: B What is the exception to the Central Dogma rule? Ans: RETROVIRUSES (process goes from RNA to ...
