RNA structure
Nucleotide substituted for thymine in RNA.
What is uracil?
Codons; UAA, UAG, and UGA.
What are translation stop codons?
Region of DNA that RNA polymerase firsts binds to in transcription.
What is a promoter?
tRNA section complementary to the mRNA codon for a particular amino acid.
What is an anticodon?
5 carbon sugar in RNA.
What is ribose?
Translation start signal.
What is AUG?
Phase of transcription where RNA polymerase is building the RNA strand.
What is elongation?
Organelle for the post-translation modification of proteins.
What is the Golgi apparatus?
Long sting of adenine added to the 3' end, which protects the molecule.
What is the poly-A tail?
A mutation that does not change which amino acid is incorporated.
What is a silent mutation?
Strand of DNA that acts as a template for the RNA.
First subunit to attach to the mRNA.
What is the small subunit?
Guanine triphosphate nucleotide added to the 5' end, which serves as an attachment point for ribosomes.
What is the 5' cap?
Molecule that bring the amino acids to the ribsomes.
What is tRNA?
Portion of the DNA that tells RNA polymerase to stop.
What is the termination site?
Mutation which scrambles the following nucleotide(s).
What is a frame-shift mutation?
Proteins which 'cut and paste' the introns and exons.
what are small nuclear ribonucleoproteins (snRNPs)?
Many amino acids coded for by more than one codon.
What is redundancy?
Direct product of transcription in eukaryotes.
Section of the ribosome where tRNA adds its amino acid.
