19 Cards in this Set

  • Front
  • Back
Transcription
the process by which from DNA RNA is created. three phases: 1.initiation 2. elongation 3. termination
RNA
(three types) functions like DNA except it contains ribose + uracil and is only one strand
mRNA
takes info from DNA and brings it to the ribosomes (out of the nucleus)
tRNA
(transfer) translates the mRNA in protein
rRNA
(ribosomal) makes up the ribosomes
RNA Polymerase
it unwinds strands, uncodes/adds proteins, and checks for mistakes
Exons
the peices of DNA that are used to express a trait
Introns
the peices of DNA that are not used to express a trait
Elongation, Initiation, Termination
the three phases of transcription
RNA splicing
this is when the introns are removed and the exons are spliced together
RNA Processing
1. introns are removed (RNA splicing)
2. adds a cap+poly A tail to the mRNA (this disguises it in order to get through the nucleus)
Translation
when RNA is made into protiens
Ribosomes
where the translation of the mRNA chain takes place
Anticodon
the opposite mRNA codon to a DNA codon. example: DNA-tac RNA-aug
Start codon
AUG the codon that signifies where the tRNA should start coding the mRNA
Stop codons
UGA tells the tRNA to stop coding
Genetic Code
the code of base pairs that expresses one's genes
codon wheel
a chart in which you can determine the protein for any tRNA codon
tRNA
(transfer) translates the mRNA into protein
