March 3 Test Flashcards
G bonds with what and has how many bonds
G bonds with C and has 3 bonds
A bonds with what and has how many bonds
A bonds with T and has 2 bonds
Introns are
Removed and not used again
Exons are
Protein coding region in the DNA
Hylacase cuts through what
Hydrogen bonds
Initiation
The RNA polymerase attaches to the promoter
Elongation
The RNA grows longer
As the RNA peels away the DNA strands rejoin
Termination
The RNA polymerase reached a sequence of bases in the DNA template called a terminator which signals the end of the gene
Codon is found on the
Messanger RNA
Anticodon is found on the
Transfer RNA
Silent mutation has
No effect
Misssence mutations have
A change in the base
Nonsense mutation
Sequence change resulting in a stop codon
Deletion
Causes everything to move up
Insertions
Causes everything to move back
Genes are on
DNA
DNA : T G A G T T A C C
*DNA: A C T C A A T G G
M-RNA: U G A G U U A C C
T- RNA: A C U C A A U G G
Amino acid - stop Val Thr
Transcription
The synthesis of RNA under the direction of DNA
Translation
The synthesis proteins under the direction of RNA
Replication
Occurs in the 5’ to 3’ template, forming short segments
Redundant
More than one codon for some amino acids
Unambiguous
Is that any codon for one amino acid does not code for any other amino acid
Nearly universal
The genetic code is shared by organisms from the simplest bacteria to the most complex plants and animals
Without punctuation
In that codon are adjacent to each other with no gals in between
