DNA Form and Function

What part of DNA's structure helps DNA polymerase know how to make an exact copy of the same bases?

• The weak hydrogen bonds between bases

• The stable structure of the backbone

• The coil shape of DNA

• The fact that bases always bond with the same partner

What part of DNA gives it different unique codes?

• The strong sugar phosphate backbone

• The different orders of bases all through the DNA

• The pairing of bases with the same partner

• The size of DNA

What helps more than 3 feet of DNA fit into a space that you can barely see with a microscope?

• The different order of nitrogen bases

• The length of DNA

• The coiling and double helix shape that can wrap up

• The weak hydrogen bonds between bases

What part of DNA's structure helps keep the code (found on the bases) safe

• The bases face the outside of the spiral

• The bases face the inside of the spiral

• There are 5 different kinds of bases in DNA

• The sugar has a ring shape.

What part of the structure of DNA allows it to store ALL the information for a cell (A LOT of info)

• The bases always pair A to T

• The hydrogen bonds between bases

• The phosphate group connected to the sugar

• DNA being 3 billion base pairs long

What part of DNA allows the double helix to be easily unzipped so it can be replicated?

• The sugar phosphate backbone is stable

• The double helix spiral shape

• The weak hydrogen bonds between bases

• The amount of DNA in each cell
