Operon systems are found... A) In prokaryotes B) In Eukaryotes C) In all prokaryotes and eukaryotes D) Only in protozoans E) All of these
Answer:
A). In prokaryotes
Explanation:
An operon is a collection of genes all under the control of the same promoter. When an operon is transcribed, all of the genes on the operon are on the same mRNA. Operons occur in prokaryotes, but not eukaryotes.
Operon systems are found... A) In prokaryotes B) In Eukaryotes C) In all prokaryotes and eukaryotes...

What is an operon? 1.Operons are sets of genes found in bacteria that are used for a shared metabolic pathway. 2.Operons are genes in eukaryotes used in development 3.Operons are sequences in prokaryotes that code for the ribosomal RNA 4.Operons are genes that have been recently transferred between bacteria
Transcriptional control of gene regulation is common in both prokaryotes and eukaryotes. Which of the following is not true? Both prokaryotes and eukaryotes: A. exhibit both positive and negative control. B. have repressors that impact expression. C. often requires interactions with DNA that is not proximal to structural genes. D. have genes that are closely related in function located proximally on a chromosome
A) What are telomeres? B) Are telomeres present in both Prokaryotes and Eukaryotes? C) Explain why some cells have telomeres and others don't (base your explanation on the structure of the DNA molecule and the directionality of polymerases).
Prokaryotes appeared long before Eukaryotes and continue to be the most abundant life form. Prokaryotes are extremely diverse, their diversity is in the result of their metabolic adaptations and their ability to rapidly change their genetic information A) Explain at least 3 metabolic adaptations of prokaryotes, and B) Compare the three ways in which bacteria exchange genetic information. C) Archaea we thought to be ancestral to bacteria. However, now they are closer to eukaryotes, what evidence supports their new placement...
