17.3 DNA Double Helix and Replication

17.3 DNA Double Helix and Replication

• The 3' hydroxyl group on the adenosine monophosphate is connected to the 5'phosphate group on the cytidine monophosphate.

• The 3' OH group is connected to the 5' carbon Try Practice Problems in the ribose of CMP.

• A G C is formed by what components join together.

• Draw a formula for the dinucleotide A T.

• The amount of adenine and guanine in a variety of organisms was determined by biologists in the 1940s.

• The sugar-phosphate backbones are similar to the outside railings of the stairs, with the bases arranged like steps inside.
• One strand goes from the 5' to 3' direction, and the other strand goes from the 3' to 5' direction.

• Each of the bases forms hydrogen bonds to only one base on the other strand.
• There are only two types of stable base pairs.
• The bases that bind using two hydrogen bonds are adenine and thymine, and the bases that bind using three hydrogen bonds are cytosine and guanine.
• There are no other stable base pairs.
• Adenine doesn't form hydrogen bonds with either guanine or cytosine.
• Equal amounts of A and T bases and equal amounts of G and C are what DNA has.

• The model shows a ribbon with hydrogen bonds between base pairs.

• The base pairs are AT and GC.

• Genetic information is preserved by Gbacteria.

• The entire double helix of the parent is copied.

• One strand is from the original DNA and the other is a new strand.

• There are exact copies of the original parent's genes.
