What does tRNA bring to the ribosome for Protein Synthesis?
What are the 2 steps of Protein Synthesis and what do they do?
- DNA makes RNA
- RNA makes proteins
Change in the nucelotide sequence of an organisms' DNA
What are the 2 types of Mutations?
- Point Mutation
- Frame-shift mutation
One nucleotide is substituted for another
Changes entire sequence beyond mutant DNA code
What are the 3 types of Point Mutations?
-Point Mutation that does not result in a change to the amino acid sequence of a protein
(they still get the same amino acid)
-Point Mutation that results in a codon that codes for a different amino acid
(their amino acids change)
-Point Mutation that results in a codon that codes for a "stop codon"
What are the 2 Frame-shift mutations?
Frame-shift Mutation that is an addition of one or more nucleotide base pairs into a DNA sequence (everything gets moved over)
Frame-shift mutation that is a a subtraction of one or more nucleotide base pairs from a DNA sequence
Which Frame-shift mutation is usually just a result of error in DNA replication?
What makes DNA unique?
The fact that the nitrogen bases can go in any order
What is the start codon?
Is it Translation or Transcription where A goes with U?
