Homework Answers
Please find the answer below:
1. In both eukaryotes and prokaryotes, gene expression can be regulated at the level of ____.Group of answer choices
Answer: a. Transcription
Explanation: In prokaryotes, gene expression is regulated at the level of transcription, whereas in eukaryotes the gene expression can be regulated at the levels of transcription, epigenetics, translation, and post-translation.
2. Which of the following is the least likely mechanism to convert a proto-oncogene to an oncogene?
Answer: d. histone acetylation
Explanation: The three mechanisms by which the proto-oncogenes are converted to oncogenes are; mutation (ex. point mutation), chromosomal re-arrangements (ex: translocation), and gene amplification.

There are some significant differences in how transcription is regulated in prokaryotes like E. coli versus eukaryotes. Which of the following statements concerning gene regulation is TRUE only in eukaryotes? (CHOOSE ALL THAT APPLY AND NO INCORRECT ANSWERS) The promoter of a gene can act in a position and distance-independent manner. The genes involved in one process are usually situated next to each other in the genome and are transcribed in one mRNA. The default state of gene transcription is...

Which of the following mechanisms to regulate gene expression are observed in eukaryotes, but are not generally observed in prokaryotes? Choose all that apply. Genes are grouped into operons, which allows transcriptional regulation to turn them all on together. RNA silencing selectively targets mRNA and destroys it to prevent further translation. Proteins can be activated or deactivated as a form of post-translational regulation. Epigenetic regulation can open or condense sectiosn of a chromosome, regulating which genes are transcribed. Regulatory proteins...

You are studying FIN1, a gene that is regulated by a microRNA in zebrafish. FIN1 is normally expressed only in the dorsal fin. You’ve isolated a DOMINANT FIN1 mutant allele that results in ectopic (abnormal) FIN1 expression in the dorsal, caudal and pelvic fins. What is a likely explanation of the nature of the dominant mutant allele? Group of answer choices A. the dominant mutation inactivates an enhancer of FIN1 B. the dominant mutant allele is a deletion mutation that...
