Unit 3-Molecular Genetics Lesson 5 4.0 Flashcards
What does the One Gene-One Polypeptide Hypothesis state?
One gene codes for one polypeptide.
What is unique about proteins composed of multiple polypeptide chains according to the hypothesis?
Each polypeptide chain has its own gene.
How do eukaryotic genes differ from simpler gene models?
Eukaryotic genes are much more complex and may not follow the One Gene-One Polypeptide Hypothesis.
What role do some genes have in relation to other genes?
Some genes control the expression of other genes.
What type of genes do not produce polypeptides?
The genes that code for RNA.
What is the problem addressed by the Genetic Code?
How do only 4 different nucleotides code for the 20 amino acids that make up proteins?
What is the solution to the problem of coding amino acids?
Each group of 3 nucleotides codes for a different amino acid.
What are the 3 nucleotide units called?
Codons.
How many nucleotides are in one codon?
3 nucleotides.
How many amino acids does one codon code for?
1 amino acid.
Example of This
DNA (C, A,T) (arrow) RNA (G,U,A) (arrow) Amino Acid: Valine
