DNA vs RNA Pretest

How confident do you feel about the topics DNA Replication and DNA vs RNA? (If you were given a test, how would you score?)

• Very confident- I would get an A on an exam

• Confident- I would pass an exam, but maybe not get an A

• Not confident- I know some details but would not pass a test

• I have no previous knowledge of either topics

RNA is different from DNA because...

• It contains adenine

• It is single-stranded

• It stays inside the nucleus

• It is not important to organisms

The nucleotide base found in RNA is called

• Uracil

• Ligase

• Glycase

• Rybocil

What does primase do?

• Unzips the two strands of DNA

• Adds DNA bases to build a new strand of DNA

• Helps glue DNA fragments together

• Helps DNA polymerase know where to start working

Ligase is used to do what?

• Unzip the double helix strand of DNA

• Helps glue the DNA fragments together

• Adds DNA bases to build a new strand of DNA

• Helps DNA polymerase figure out where to start working

The sugar in RNA is called...

• Ribose

• Rybocil

• Ligase

• Thymine

In RNA, adenine goes with __________.

• adnine
• cytosine

• uracil

An enzyme usually is a word ending in...

• -ose

• -in

• -ase

• -ate

What does DNA polymerase do?

• Unzips the two strands of DNA

• Adds DNA bases to build a new strand of DNA

• Helps glue DNA fragments together
