None of these are transcription enzymes

What is genetic engineering?

Naturally breeding two animals with desired traits

DNA containing genes foreign to that organism

DNA which has been impacted by epigenetics

DNA that has restriction enzymes

What is a restriction digest?

Using enzymes to cut DNA at specific locations

Using enzymes to replication DNA

Using science to make genetic clones

Analysis of DNA with an electrical current

YOU did a restriction digest to....

Confirm the presence of rfp in your pARA-R plasmid

Remove the rfp from anemone DNA

Which products are not made from gene therapy?

bacteria to digest oil for oil spills

How do we describe transformation in bacteria?

assimilation of external DNA into a cell

the creation of a strand of DNA from an RNA molecule

the creation of a strand of RNA from a DNA molecule

the infection of cells by a phage DNA molecule

What makes up a spliceosome and what does a spliceosome do?

proteins & snRNPs, cuts out introns & reconnects exons

proteins & snRNPs, cuts out DNA pieces

proteins & snRNPs, cuts out exons & reconnects introns

many nucleosomes, cuts the cheese

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 proteins expressed in each cell are different

The two different cells become mutated

They actually have different DNA in the two types of cells.

The genome of the different cells changes

Why are insertion and deletion (frameshift) mutations so harmful?

They change all of the codons from the mutation on down the line, which changes the amino acid sequence

They insert things that an organism doesn't need.

They often delete things that organisms need.

Insertion and deletions are not any more harmful than substitution mutations.

Which of the following correctly describes exons ? Choose ALL that apply.

They may remain in mRNA after editing.

They are usually removed from mRNA during editing.

Which of the following correctly describes introns ? Choose ALL that apply.

They are usually removed from mRNA during editing.

They may remain in mRNA after editing.

A protein produced by a freely floating ribosome could serve which of the following functions? (Choose ALL that apply.)

Metabolic enzymes remaining within the cell

Structure/support within the cell (e.g. cytoskeleton)

Digestive enzyme inside a lysosome

Channel or receptor proteins embedded in the cell membrane

Hormones or other messages secreted from the cell via vesicles

A protein produced by a ribosome bound to the rough ER could serve which of the following functions? (Choose ALL that apply.)

Digestive enzyme inside a lysosome

Channel or receptor proteins embedded in the cell membrane

Hormones or other messages secreted from the cell via vesicles

Metabolic enzymes remaining within the cell

Structure/support within the cell (e.g. cytoskeleton)

Which of the following statements correctly describe differences between DNA and RNA? Select all that apply!

RNA contains ribose sugar, while DNA contains deoxyribose

RNA contains the base uracil, while DNA contains thymine

RNA is single stranded, while DNA is double-stranded

DNA can have catalytic properties, while RNA cannot

a unit made up of linked genes that code for proteins needed to do a specific task

a unit of a ribosome that is necessary for translation

an enzyme needed for DNA replication

Alternative RNA splicing ____.

can allow the production of proteins of different sizes and functions from a single mRNA

is a mechanism for increasing the rate of translation

can allow the production of similar proteins from different RNAs

increases the rate of transcription

Which of the following statements best describes the termination of transcription in prokaryotes?

RNA polymerase transcribes through the polyadenylation signal, causing proteins to associate with the transcript and cut it free from the polymerase

RNA polymerase transcribes through the terminator sequence, causing the polymerase to separate from the DNA and release the transcript.

RNA polymerase transcribes through an intron, and the snRNPs cause the polymerase to let go of the transcript.

Once transcription has initiated, RNA polymerase transcribes until it reaches the end of the chromosome.
