This is an image of a(n) ______.

The letter A indicates a ________.

A nitrogen base is indicated by the letter

Nucleic acids are assembled in the ______ direction.

Match the following enzyme to its description.

Draggable item		Corresponding Item
DNA polymerase I		Joins the 3’ end of DNA that replaces primer to rest of leading strand and joins Okazaki fragments of lagging strand
Primase		Removes RNA nucleotides of primer from 5’ end and replaces them with DNA nucleotides
Single Stranded Binding Proteins		Binds to and stablizes single stranded DNA until it can be used as a template.
DNA polymerase III		Synthesizes an RNA primer at 5’ end of leading strand and of each Okazaki fragment of lagging strand
helicase		Using parental DNA as a template, synthesizes new DNA strand by covalently adding nucleotides to the 3’ end of a pre existing DNA strand or RNA primer.
DNA ligase		Unwinds parental double helix at replication forks

single-ringed pyrimidines

amino acids

Each of the four nucleotides in a DNA molecule has the same nitrogen-containing base.

When adenine base pairs with thymine, they are linked by three hydrogen bonds.

In the DNA of all species, the amount of purines never equals the amount of pyrimidines.

sugar and phosphate 

amines and purines

natural

lytic
