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
generates excessive DNA, which eventually causes the nucleus to divide.
is too complex to characterize
nitrogen base
sugar
none of the above
4'...5'
5'...1'
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
