Transcription
What is the name of the process that converts genetic information in DNA into mRNA?
Transcription
What organelle or structure attaches to the mRNA to start the process of translation
Ribosome
in RNA T is replaced with ___.
U
substitution
This is where DNA is stored
Nucleus
Where in the cell does transcription occur?
Nucleus
what does each codon on the mRNA molecule code for?
Protein blocks (amino acids)
a triplet of nucleotides is called a
Codon
When 1 or more bases is removed from the sequence it is called: _______
deletion mutation
This is the process by which the information in a strand of DNA is copied into a new molecule of messenger RNA (mRNA).
Transcription
What molecule carriers the genetic code from the nucleus to the cytoplasm?
mRNA
What is the first code for every mRNA sequence?
AUG
What is the start codon?
AUG
when a based is added to the sequence, the mutation is called ________
Insertion
This molecule transfers specific amino acids to the ribosome during translation.
tRNA
What is the enzyme that create the mRNA during transcription?
RNA polymerase
translation ends with this codon
stop codon
What is the protein chain for the following DNA sequence.
TAC TTT AAT CGC
Met - Lys - Leu - Ala
What happens in a nonsense mutation?
early stop in the gene
The copy of DNA is called
RNA
Before mRNA leave the nucleus there is one last final step to edit the RNA. Describe what happens during this editing process?
enzymes cut out information that is unwanted and glue informations that are wanted together.
What is the name of the scientific a protein chain after it is created
Polypeptide
Using the codon chart, which 3 amino acid has the most codons?
arginine (arg), Leucine (Leu), and Serine (ser)
What type of mutation results in no change to the amino acid sequence of the protein?
Silent Mutation
These are the protein-RNA complexes that remove unwanted sections from mRNA and connect wanted sections together
Spliceosomes
