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...

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...

An Ames test of a compound suspected to be a mutagen was examined before and after incubation with rat liver extract. Based on the results shown, what do you conclude? correct answers Compound is mutagenic without liver enzymes and this activity is further enhanced by liver enzymes Lynch syndrome is a human genetic disease characterized by ~100-fold higher incidence of colon cancer in men and women - and uterine cancer in women - by the age 50, as compared to the general population. Which sta...

PCB 3023 Exam 2: Transcription and Translation Practice Questions and Answers (100% Pass) does the structure of the DNA (nucleosomes) impact the ability of the RNA polymerase to transcribe genes? - Answer️️ -- yes - tightly bound nucleosomes, it's harder to get to the DNA so there is less expression - DNA is more exposed when the histones aren't packed together so tightly dna transcription vs replication - Answer️️ -- replication synthesizes new (daughter) DNA - transcriptio...

C) covalent bonds to form between the opposite bases. D) replication to be semiconservative. E) DNA to serve as its own template for replication. - CORRECT ANSWER E) DNA to serve as its own template for replication. 6) The process by which genetic information is transferred from DNA to RNA is called ...

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 ...
