Study Guide (DNA and RNA) #1 Flashcards
the basic chemical unit of a nucleic acid
nucleotide
transforming factor that alters pneumonia bacteria
DNA
the two kinds of nucleic acids
dna and rna
the three parts of every nucleotide
sugar phosphate base
a pair of these forms a rung in the DNA ladder
base
used to label DNA and protein in experiments
radioactive isotope
the component of a bacteriphage that enters the host cell
DNA
two alternating parts that form the nucleic acid backbone
sugar phosphate
the four bases in DNA
Adenine cytosine guanine thymine
the dna base complmentary to T
adenine
a virus that attacks bacteria
bacteriophage
the substance a phage leaves outside its host cell
protein
ribose in rna and deoxyribose in DNA
sugar
watson and crick deduced the structure of this molecule
dna
attacked by herpes virus
nerve cell
the dna base complementary to G
cytosine
a bacterium attacked by T2 phages
E. coli
the sequence of these encodes DNA information
base or nucleotide
eukaryotic chromosomes consist of this and dna
protein
the overall shape of a dna molecule
double helix
machine used to separate particles of differenet weights
centrifuge
links adjacent nucleotides in polynucleotide chain
covalent bond
links a complementary pair of bases together
hydrogen bond
the four bases in Rna
adenine cytosine guanine uracil
rna base that is not in dna
uracil
a polymer of nucleotides
polynucleotide or DNA or RNA
causes cold sores, chickenpox, and other diseases
herpesvirus
