The genetic code is determined by 

Option: 1

Epigenetic modifications 

Option: 2

Codons within DNA sequences

Option: 3

Environmental Factors

Option: 4

Post-translational modifications

Answers (1)


The genetic code refers to the specific sequence of nucleotides within DNA that determines the sequence of amino acids in a protein. This code is carried by codons, which are specific sequences of three nucleotides within the DNA molecule. Each codon codes for a specific amino acid or serves as a start or stop signal for protein synthesis. Therefore, the correct answer is Option 2) Codons within DNA sequences, as they are the fundamental units that determine the genetic code.

Option 1 is incorrect because Epigenetic modifications, such as DNA methylation or histone modifications, can affect gene expression, but they do not directly determine the genetic code itself.

Option 3 is incorrect because Environmental factors can influence gene expression and protein synthesis, but they do not determine the specific codons within DNA sequences.

Option 4 is incorrect because Post-translational modifications occur after protein synthesis and can modify the structure or function of proteins, but they are not directly involved in determining the genetic code.
