Don't know?
Adenine
Guanine
Nitrogenous bases of DNA
Thymine
Cytosine
Contain 2 carbon-nitrogen rings, Purines - A and G
and 4 nitrogen atoms
Contain 1 carbon-nitrogen ring, Pyramidines - T and C
and 2 nitrogen atoms
Deoxyribose sugar chemically linked to each base in DNA
, Nucleoside base + deoxyribose
Nucleotide base + deoxyribose + phosphate group
purine always pairs with pyramidine
complementary pairs
(T+A), (C+G)
Occur when 2 negatively Hydrogen bonds
charged atoms share a
hydrogen atom
# of hydrogen bonds between A two
and T
# of hydrogen bonds between C three
and G
specified linear arrangement of nucleotides linked to the
sequence
polynucleotide chains of DNA. Defines the entire organism
end terminating with a 5' (five prime) end
phosphate group
end terminating with a hydroxyl 3' (three prime) end
group
one side of the helix runs in the opposite (5'-3') direction of the
antiparallel arrangement
other (3'-5)
Genome entire sequence of paired bases in DNA
A simple protein bound to DNA, involved in the coiling of
histone proteins
chromosomes
Chromatin DNA sequences and their associated proteins
Chromosomes structures of packaged chromatin complexes
Somatic cell All of the body's cells except gametes
Number of chromosomes in 46 (23 pairs)
each somatic cell
Process of parent cell replicating its genetic info and dividing
Cell cycle
into 2 new daughter cells
cytokinesis division of the cytoplasm
interphase G1, S, G2 phases. 90% of cycle time.
Gap phase 1 First phase, growth phase
Messenger RNA (mRNA) transfers genetic info from DNA to ribosomes
site of protein synthesis ribosomes
S phase DNA duplication phase, lasts 10-12 hours
Second growth phase, when synthesis of organelles and proteins
G2 phase
needed for mitosis occurs. Lasts 4-6 hours.
