mutations
100
discovered that the nucleic acid DNA stores and transmits the genetic information from one generation of an organism to the next
Who is avery
100
the RNA molecule that carry copies of instructions
What is mRNA
100
3-base pair
What is codon
100
segment of DNA that codes for a particular protien
What is a gene
100
changes in genetic material
What is mutation
200
a long molecule made up of units
What is nucleotides
200
enzyme that builds mRNA
What is RNA polymerase
200
polymerase binds to DNA and separates the DNA strands
What is transcription
200
3 differences of RNA and DNA
What is the sugar in RNA is ribose instead of deoxyribose, RNA is generally single stranded and RNA contains uracil instead of thymine
200
gene mutations involving changes in nucleotides
What is point mutations
300
virus that infects bacteria
What is bacteriophage
300
transfers each amino acid to the ribosome as as it is specified by coded messages in mRNA
What is tRNA
300
3 unpaired bases
What is anticodon
300
hydrogen bonds can form only between adenine and thymine, and cytosine and guanine
What is base pairing
300
condition in which an organism has an extra set of chromosomes
What is polyploidy
400
concluded that the genetic material of the bacteriophage was DNA not protein
Who is Hersey and Chase
400
makes up ribosomes
What is rRNA
400
the cell uses information from messenger RNA to produce proteins
What is translation
400
a process in which DNA duplicates itself
What is replication
400
shift of 'reading frame" of the genetic message
What is frameshift mutation
500
Concluded that DNA was a double-helix and in which two strands were wound around each other
Who is Watson and Crick
500
sequence of bases on DNA that tells polymerase to stop here
What is Terminator
500
sequence of bases on DNA that tells the polymerase to start here
What is promoter
500
segment of DNA that codes for a particular protein
What is gene
500
group of genes that work together
What is operon
