DNA Flashcards
How does DNA decide what amino acids will make up a protein?
DNA sequence decided order of mRNA bases, mRNA bases decide what amino acids bond
Compare Transcription and Translation
- C and G bond together
- DNA must be unzipped first
Why does mRNA go to ribosomes?
That is where the proteins are assembled
U replaces what base?
Thymine (t)
What does m in mRNA stand for?
Messenger
Single strand that delivers messages:
mRNA
(Nucleus) -> uuu acg cca -> Ribosomes
Is this transcription or translation?
Translation
What does t in tRNA stand for?
Transfer, because it transfers amino acids to the ribosome
What is a codon?
Set of 3 nucleotides
Summarize DNA replication:
Step 1, DNA Unzips
Step 2, Freed nucleotides bond to exposed bases
Why is DNA called Semiconservative?
1/2 is old strand
1/2 is new strand
What needs to separate for DNA replication?
Hydrogen Bonds
Why do we need DNA replication?
Every cell needs a complete copy of DNA, so it needs to be copied for cells to divide
When does DNA replication take place?
Interphase
Where is DNA replication in a Eukaryotic cell?
Nucleus
