How to Play
Definition / ConceptTerm
code for Ochre
a system which is always on because the repressor cannot bind to DNA
the size of the bacterial ribosomal unit
code for Amber
the size of the small subunit of the eukaryotic ribosomal unit
protein which binds to origin and separates strands
a gene which retains the same function despite a change in sequence
moves ahead of the replication fork making and resealing breaks in the double-helical DNA to release torque that builds up as a result of unwinding the DNA at the replication fork
the size of the eukaryotic ribosomal unit
attach to single-stranded DNA and prevent reannealing
elongates a new nucleotide strand from the 3' OH group provided by the primer
Stop codon UGA
a base pair mutation which causes the codon to code for a different amino acid
the size of the large subunit of the bacterial ribosomal unit
a membrane-bound protein which creates a channel allowing lactose in
removes RNA primers and replaces them wit DNA
synthesizes short RNA primers to provide a 3' OH group for the attachment of the DNA nucleotides
Definition / ConceptTerm
this is needed to get RNA polymerase to start “doing its job” – will be several aborted attempts before success
joins okazaki fragments by sealing nicks in the sugar-phosphate backbone of newly synthesized DNA
the addition or subtraction of 1-2 bases which causes the reading frame of DNA to shift and makes the codons shifted and causes the wrong amino acids to be coded for and produced
how “right” replication is
a gene which has an altered sequence resulting in an altered function
the size of the small subunit of the bacterial ribosomal unit
code for Umber
the conditions necessary for conditional mutation to take place
base change from a purine to a pyrimidine or vise-versa
a base pair mutation which causes the codon to code for the same amino acid
the size of the large subunit of the eukaryotic ribosomal unit
the speed of replication or the number of base pairs replicated in one burst of replication with DNA polymerase
Stop codon UAG
a base pair mutation which causes a STOP codon
Stop codon UAA
unwinds DNA at the replication fork
base change from a purine to a purine or a pyrimidine to a pyrimidine
