a single building block of DNA, one deoxyribose sugar, one phosphate group, and one nitrogen base
Adenine and Guanine, 2 ring structures
Cytosine and Thymine, 3 ring structures
The opposite arrangement of the sugar-phosphate backbones in a DNA double helix.
a protein which DNA entwines/ wraps around
substance found in eukaryotic chromosomes that consists of DNA tightly coiled around histones, DNA and its proteins
replicated DNA consists of one original strand and one new strand, each new DNA conserves half of the original
causes the DNA double helix to unzip during DNA replication
An enzyme that joins RNA nucleotides to make the primer
enzyme involved in DNA replication that joins individual nucleotides to produce a DNA molecule, can only add bases to an existing nucleic acid strand
enzyme responsible for joining strands of DNA, seals the sugar-phosphate backbones of the pieces, "to tie"
rewinds any sections of the DNA molecule that remian unwound
short segment of RNA used to initiate synthesis of a new strand of DNA during replication
enzyme that binds to DNA and separates the DNA strands during transcription
a new DNA strand, up to 150 nucleotides long, small pieces of DNA
