Transcription occurs in what direction?

5' -> 3'

100

Where does transcription occur in Prokaryotes?

Cytoplasm

100

What is the gap formed by unwound DNA called?

Transcription bubble

100

After a eukaryotic cell is done transcribing mRNA, where does the new strand go?

Outside of the nucleus to a ribosome.

100

True or False: All genes are being transcribed nonstop.

False

200

What is the strand of DNA called that is being replicated?

Template Strand

200

Where does transcription occur in Eukaryotes?

Nucleus

200

Do eukaryotes or prokaryotes transcribe faster?

Prokaryotes

200

What is required on the mRNA strand to be able to leave the nucleus?

5' cap, removal of introns, addition of a poly A tail

200

True or false: In prokaryotes, transcription and translation occur at the same time.

True

300

True or False: Both strands of DNA are transcribed at the same time.

False

300

Eukaryotes: What regulated the RNA Polymerase II to facilitate transcription?

Enhancer Sequence

300

Which enzyme surrounds the DNA as it is being replicated?

RNA Polymerase II Complex

300

What is the matching code of mRNA for this DNA template? 

AGCGTTATC

UCGCAAUAG

300

What are the genes called that ARE being transcribed all the time?

Housekeeper genes

400

What is the name of the box at the end of the promoter sequence called?

TATA box

400

Prokaryotes: What is the name of the factor that is associated with RNA polymerase and recognizes the promoter sequence?

Sigma Factor

400

How many phosphates enter on a ribonucleotide and how many stay attached and build the RNA?

3 enter (ribonucleoside triphosphate)

1 remains (2 get kicked off and release energy)

400

Is uracil a pyrimidine or a purine?

Pyrimidine

400

Approximately how many base pairs are in the RNA-DNA duplex?

8

500

Which enzyme unwinds DNA for replication?

DNA Helicase

500

Eukaryotes: Which enzyme facilitates local unwinding of DNA and adds nucleotides?

RNA Polymerase II

500

Channels in the transcription enzyme allow for what material to enter the bubble?

RNA nucleotides

500

Why is the 5' cap needed before transcription can occur?

The new strand needs the cap in order to get through the nuclear membrane and leave the nucleus.

500

Introns and Exons: Which groups are removed and which are spliced together?

Introns are removed and Exons get spliced together.
