Each DNA base codes for three amino acids.
B
Each gene codes for three proteins.
C
It takes three genes to code for one protein.
D

검증된 단계별 안내1
Understand the basic concept of the genetic code: DNA is composed of sequences of nucleotides, and these sequences are used to code for proteins.
Learn about codons: A codon is a sequence of three nucleotides in DNA or RNA that corresponds to a specific amino acid or stop signal during protein synthesis.
Recognize the relationship between DNA bases and amino acids: Each amino acid in a protein is coded for by a sequence of three DNA bases, known as a codon.
Explore the process of translation: During translation, the sequence of codons in mRNA is read by the ribosome to assemble amino acids into a polypeptide chain, forming a protein.
Clarify the statement: The correct statement is that each amino acid in a protein is coded for by three bases in the DNA, which are organized into codons.
