Chargaff
The double-helix theory was proven by this scientist, who took a picture of the structure
Who is Rosalind Franklin?
Packaging is important for this reason
What is the length of DNA is ~a million times bigger than the nucleus?
This DNA form is the most common, and the one most people recognize as DNA
What is B-DNA?
The DNA that contains one complete copy of the genetic information is called this
What is genome?
What is identifying the base pairs?
The structure of DNA is a polymer with these parts
What is a backbone of sugar and phosphate groups?
This is the group of proteins associated with DNA packaging
What is histone?
Z-DNA is named so for this reason
What is its zig-zag patterned backbone?
Prokaryotes have this kind of DNA
What is circular?
Chargaff's rules states this about DNA base percentage in different cells
What is the percentage of the four bases stays the same?
The antiparallel orientation of the double helix means these ends go together
What is 5'-->3'and 3'-->5'
Nucleosomes are a structure of these molecules
What is a circle?
Generally, this is what happens to genome size as an organism becomes more complex
What is increases?
You would expect see this kind of composition of DNA in closely related species
What is similar composition?
The nucleotide staircase has this many nucleotides per turn
What is ten nucleotides?
Chromatin packing has five levels, with the final product being this structure
What is chromosome?
First identified in viruses, supercoiled DNA looks like this
What is twisted upon itself?
Eukaryotes have this many kinds of DNA
What is linear and and circular?
These bases are purines, while these bases are pyrimidines
What is adenine and guanine, and what is cytosine and thymine?
The different grooves of the helix play different roles, with this groove being the direct readout site for information, and this groove being the target for a few regulatory and structural proteins
What is major groove and minor groove?
The protein scaffold has this role in the packing of DNA
What is organizing the DNA into looped domains?
Z-DNA, the left-handed helix, arises in regions of DNA with these alternating structures
What is purines and pyrimidines, and what is cytosines and extra methyl groups
You can find this kind of eukaryotic DNA in mitochondria and plastids, and this kind of DNA in a nucleus
What is circular, linear?
