dna replication recap Flashcards
what is the way that ALL organisms carry genetic material
nucleic acid
what is cell division for in unicellular and multicellular life
- reproduction
-growth
what is binary fission
doubling of dna
how many base pairs do E. coli have
4.6 x 10^6 bps
what has the smallest genome
bacteriophage
what are the nucleotide monomers
adenosine, cytidine, guanosine, thymidine
which bases are purines
adenosine and guanosine
which bases are the pyrimidines
cytidine and thymidine
how many bases pairs and nucleotides does one turn of the helix have
10.5 bps
~10 nucleotides
what are the three key structural features of dna
-double helix
-right handed
-anti- parallel
how many h bonds does G-C and A-T have
G-C has 3
A-T has 2
why can’t bind you G-T or A-C
as they would be different widths
what is semi-conservative replication
when you separate the DNA into two strands and let free nucleotides bind to the template strand
which experiment proved semi-conservative replication
meelson and stahl
what enzyme is required for PCR
Taq dna polymerase
