Quiz 24 Redo: Transcription

Quiz 24 Redo: Transcription

By Scott Snyder

DNA can be copied using DNA polymerase during S phase

​

DNA can be "read" using RNA polymerase. This is called transcription

​

RNA polymerase is faster, but with more errors than DNA polymerase

​

​Copy vs. Read

​

Multiple Choice

What "Reads" DNA?

• RNA polymerase

• DNA polymerase

Multiple Choice

What copies DNA?

• DNA polymerase

• RNA polymerase

Multiple Choice

Which has the greater "error rate"

• DNA polymerase

• RNA polymerase

Multiple Choice

Which is true?

• DNA is transcribed into RNA

• RNA is transcribed into DNA

Multiple Choice

How many strands of RNA are created from the DNA?

• 1

• 2

Template strand = DNA strand used to base pair and make RNA

​

​Coding strand = Strand that looks the most like the resulting RNA. Not used to make RNA

​

Multiple Choice

Which strand of DNA is used to create RNA?

• Template strand

• Coding Strand

​Different from DNA replication.

​

DNA replication: A - T, C - G​

​

Transcription: A - U, C - G​

​Base Pairing Rules

​

RNA vs. DNA

Multiple Select

RNA (check all that apply)

• single stranded

• double stranded

• ribose sugar group

• deoxyribose sugar group

• Inherited

mRNA - a message to the cell. Is used as information to make protein

rRNA​- folds on itself to create a ribosome (the worker of the cell)

​tRNA - folds on itself to create an enzyme used to gather amino acids

​

​

​

3 types of RNA made:

​

Multiple Select

fold on themselves to make enzymes (check all)

• mRNA

• rRNA

• tRNA

Multiple Choice

Is information used to build human proteins

• mRNA

• tRNA

• rRNA

Take out "junk" called introns. Leave Exons. Attach a lot of A's (so the cell knows what it is). ​

Splicing

Multiple Choice

What is removed from mRNA to make mature mRNA?

• introns

• exons

Multiple Choice

The process of removing introns

• slicing

• transcription

• translation

• splicing
