Gene regulation Eukaryotic and Transformation

What are the building blocks of proteins called?

• DNA
• RNA
• Ribosomes
• Amino Acids

When does alternative splicing occur?

• after translation

• after transcription

• before transcription

• after post-translational modifications

In embryonic development,  the process by which cells specialize is called

• differentiation
• morphogenesis
• cell division
• endoplasmic reticulum

How can a person's muscle cells have the same exact DNA sequences as their nerve cells even though the look and perform completely different?

• The two different cells become mutated
• Different genes are expressed and therefore different proteins are synthesized
• They actually have different DNA in the two types of cells.
• The genome of the different cells changes

The most important sequence in promoter for RNA polymerase to bind to is . . . .

• the exons

• the first intron

• TATA box
• the activators

What do promoter elements bind to regulate eukaryotic transcription?

• Transcription Factors
• RNA Polymerase II
• Sigma
• mRNA

A distal control region, that is bent to contact mediator proteins and form the transcription initiation complex.

• enhancers
• promoters
• repressors
• transcription factors

In eukaryotes, a cluster of proteins that assemble on the promoter is called the

• transcription initiation complex
• control element
• activator
• protein blobby thing

Which of the following is one way that transcription is controlled in eukaryotes?

• The AUG codon

• Through RNAi

• Through the use of operons
• Methylation and Acetylation

In order for a gene to be expressed, ___ must bind to the gene's ___, a specific sequence of nucleotides at one end of the gene, thus initiating transcription.

• DNA polymerase, promotor

• DNA polymerase, operator

• RNA polymerase, promotor

• RNA polymerase, operator
