8 and 9 Flashcards
some eons are removed or joined in various combinations
alternative splciing
Its anticodon base pairs with first AUG codon of mRNA
initiator tRNA
Helps finished mRNA bind to ribosome
5’ cap
Process by which info in a gene guide assembly of RNA or protein product
gene expression
allows mRNA to be exported from nucelus
poly A tail
In DNA, a sequence to which ran binds
promoter
other type
beta thalassemia
Stop Codons
UAA, UAG, UGA
The chart is called the
genetic code
codon chart
mRNA
specifies order of aa sequnece
all ran result from
transcription
trna
delivers aa to ribosome
3’ end is
hydroxyl – aa is attached here
splisosomes in
transcription
guanine cap goes to
5’ end
poly A tail goes to
3’ end
poly A allows for
export from nucleus
how many binding sites on ribosomes
3
the anticodon trna has in complementary to
AUG
The amino acid tRNA is carrying is
met
in first steps
small subunit attaches to mRNA at start codon
What was in
What was in A site goes to the p site, leaving the a site free
which site does tRNA go to
p site
Stop and start codons found in
mRNA
in sickle,
substitute A for T
3’ end
amino acid
5’ end
anticodon
change in DNA level, but not refelected in sequence
silent mutation
sickle cell
1 nucleotide makes valine in I beta chain, won’t carry 02 well
terminator shows up early
nonsense
RIP
ribosome inactivating protein
results in a codon that codes for a different amino acid.
missense mutation
t for
trouble
