Study Notes
Biology Quiz: DNA and Amino Acids
- A biology quiz question asks about the significance of three consecutive nucleotides in DNA
- The possible answers relate to how these nucleotides code for amino acids or proteins
- Three consecutive nucleotides in DNA are important for encoding specific genetic information
- The correct answer is likely A: They code for one amino acid, as a sequence of three nucleotides (a codon) typically specifies one amino acid in protein synthesis
How DNA Base Changes Affect Protein Production
- A single change in a DNA base can produce a different protein by altering the amino acid sequence.
- This change in amino acid sequence can result in a protein with distinct properties or functions.
- Note that changing the DNA base does not directly affect peptide bonds, mRNA production, or mRNA transport out of the nucleus.
