Question | Answer |
---|---|
What does DNA stand for? | deoxyribonucleic acid |
What do we call the process for 'writing' the DNA code to mRNA? | Transcription |
What are the 3 parts to the RNA nucleotide? | ribose sugar, phosphates, & C-G-A-uracil |
What are the 3 parts of DNA Nucleotide? | deoxyribose sugar, phosphates, & C-G-A-thymine |
DNA is double-stranded while RNA is what? | single-stranded |
Every 3 nitrogen bases on DNA and mRNA are known as a what? | codon |
All amino acids are coded by 1 or more what? | codons |
The code on DNA is universal meaning that the amino acids and their codons are the same for what? | all living organisms |
What would the codon AGC be when transcribed to mRNA? | UCG |
What is the job of mRNA? | to carry the DNA code to the ribosome. |
Where does transcription occur? | in the nucleus |
What is the job of rRNA? | to read the mRNA codons at the ribosome one codon at a time |
What is the job of the tRNA? | to match its anticodon with the proper codon on the mRNA at the ribosome & bring in the correct amino acid |
What is the process called where the mRNA code is used to make a chain of amino acids at the ribosome? | Translation |
Where does Translation happen? | at the ribosome |
How is the correct amino acid brought to the correct codon on the mRNA at the ribosome? | the tRNA with the correct anticodon will bring the correct amino acid |
The string of amino acids built by tRNA are held together by what? | peptide bonds |
The string of amino acids built by translation eventually become what? | a protein |
What is a mutation? | a change in the DNA nitrogen base sequence |
Where is the code for proteins in the DNA molecule? | in the order of nitrogen bases |
What is a mutagen? | a mutation causing agent |
What kind of mutation results from the change in one nitrogen base in the DNA sequence? | point mutation |
What kind of mutation results from the loss or gain of one nitrogen base in the DNA sequence? | frameshift mutation |
