Chapter 8.5 Flashcards
What are amino acids coded by?
mRNA base sequences.
What does translation convert an mRNA message into?
A polypeptide or protein
What is a codon?
A sequence of three nucleotides that codes for an amino acid
What is a protein made out of?
Many amino acids.
What does the genetic code match each codon to?
Its amino acid or function.
How many STOP codons are there?
3
How many start codons are there, and what does it code for?
1 and it codes for methionine
How can the resulting protein be affected?
A change in the order of which the codons are read.
Codons code for the same…
Amino Acid
Why are amino acids linked?
to become a protein.
A set of 3 nucleotides that are complementary to an mRNA codon.
anticodon
What is an anticodon carried by?
tRNA
How many subunits does ribosomes consist of?
2
What are the subunits of ribosomes characteristics?
The large subunit has three binding sites for tRNA
The small subunit bind to mRNA
For translation to begin, what has to happen?
tRNA has to bind to a start codon and signal the ribosome to assemble.
