Replication correct answers DNA must be retained intact, yet copied to make new cells Transcription correct answers DNA must be turned into multiple "working copies" to provide instructions for enzymes/structural proteins production Translation correct answers RNA must be read and decoded to form the enzymes/structural proteins of the cell DNA repair correct answers systems must have the ability to deal with damage Transcription in Bacteria correct answers - involves RNA polyme...

BIOL200 SimUText questions with Complete Solutions what is the function of a gene? to contain information for building specific cellular products what proteins are encoded by genes? proteins that maintain cell membranes proteins that help convert sugar to energy protein channels that allow molecules in and out of cells When cells make proteins, is the gene in the DNA destroyed or used up in the process? No, the information in DNA is copied into a molecule of RNA How are DNA, RNA and polypepti...

What are elongation factors? (transcription) - ️️use ATP hydrolysis to help RNA poly. move along chromatin -make sure RNA isnt falling off DNA/ skipping nucleotides Differences between eukaryotic and prokaryotic transcription - ️️- Euk: Have 3 different RNA polymerases. Pro: only one - Starting --- Euk: Needs general transcription factors to start transcription and position RNA polymerase. Pro: RNA polymerase binds to promoter sequence immediately. - Stopping --- Euk: Polyadenylat...

A) rRNA B) mRNA C) tRNA D) miRNA E) A, B, and C all get translated. - CORRECT ANSWER B Which of the following RNA molecules are required for the process of translation? A) crRNA B) tRNA C) snRNA D) snoRNA E) siRNA - CORRECT ANSWER B Over time, DNA replaced RNA as the primary carrier of genetic information, and the chemical stability of DNA is believed to be...

two parts of holoenzyme (helper to RNA polymerase in transcription in bacteria) correct answers core enzyme and sigma factor (determining correct location for transcription) transcription in bacteria correct answers sigma factors bind to RNA pol core enzyme and direct it to promoter transcription prceeds different sigma factors different genes ways to stop transcription correct answers rho-dependent and rho independent rho dependent correct answers rho protein follows RNA pol and...

Bio 101 Chapter 7 Exam Questions and Answers All Correct A change in a cell's DNA sequence is Select one: a. transcription. b. a mutation. c. an operon. d. translation. e. replication. - Answer-b. a mutation A diploid cell only has two copies of most genes, but can make hundreds of copies of a protein from those genes per second because Select one: a. while transcription can repeat and make multiple mRNA copies of genes, and multiple ribosomes can translate the same mRNA. b. mult...

Microbiology Chapter 8 Exam Questions with 100% Correct Answers | Verified | Updated What characteristic of DNA allows two connected DNA polymerases to synthesize both the leading and lagging strands? DNA has a helical shape. DNA is double-stranded. DNA is antiparallel. DNA is flexible. - answerDNA is flexible. What is the function of the connector proteins? They enable one parental DNA strand and one newly synthesized DNA strand to be held together. They allow DNA synthesis to occur...

ASCP MB: Extra-Practice Questions and Answers Scored A The Klenow fragment of E. coli DNA polymerase I is used: - Answer ️️ -to label DNA probes by random primer labeling. What is a solution hybridization method for the detection of nucleic acid:protein interactions? - Answer ️️ -gel 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...

alternative splicing - - Splicing of introns in a pre-mRNA that occurs in different ways - leads to different mRNAs that code for different proteins - Increases the diversity of proteins. dna transcription vs replication - - replication synthesizes new (daughter) DNA - transcription of DNA forms RNA does the structure of the DNA (nucleosomes) impact the ability of the RNA polymerase to transcribe genes? - - yes - tightly bound nucleosomes, it's harder to get to the DNA so there is less e...

iology 1000 – Principles of Biology ( BioS 115 Core II: Genetics) Exam Study Guide. 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 # with the genotype Expressi...
