Homework Answers
Option E is the correct answer.
In both eukaryotes and prokaryotes expression of a single gene is regulated by several general transcription factors.

QUESTION 9 Regulation of gene expression by eukaryotes is more complicated that in prokaryotes. The promoter region contains proximal regulatory sequences that are called _regulatory elements. These proximal regulatory elements bind trans-acting proteins that are called __factors.

Looking at the diagram of transcription in eukaryotes and using the
information provided, how could the expression of lactase RNA be
turned on and off by transcription factors, activators and
repressors?
Styles Font Paragraph Activators bind to genes at Rapressors bind to genes seauences and at shaoser sequences and The expression of RNA in eukaryotes is initiated by the binding of basal transcription factors to the promoter sequence of a gene. This leads to the recruitment of RNA polymerase to...

Regulation of Gene Expression in Eukaryotes In eukaryotes, the Central Dogma of Genetics can be expanded to include post-transcriptional processing and post-translational processing, thus the Dogma becomes: Replication - Transcription Post-transcriptional Processing -Translation - Post-translational Processing - Functional Protein - Expressed Trait. This is the flow of information from the genetic material to the actual physical, chemical or behavioral trait in an organism. Of course, some traits are controlled by multiple genes and some also have an environmental component. At...

The following is a diagram of the LCT (lactase gene) gene
regulation system in humans. When the LCT gene is transcriptionally
active, the cell produces the enzyme lactase, which is
needed to digest the lactose in many dairy products. Based on what
you know about enhancers and promoters from your reading, predict
how the following scenarios might influence LCT gene expression and
thus lactase production in cells:
The enhancer sequence is inverted, but remains intact so that
Oct1 still binds...
