Homework Answers
Option B is correct. Within the sequence of nucleotides. Nucleotide sequence forms gene that has all the information for activity. Genes are the nucleotide sequences that undergo transcription, translation and also modification to form sequence of amino acids called protein.

Genetic Code: The dictionary of the language of life Use the Genetic Code as a "dictionary" to solve the exercises on next page 5. If a mutation happens in the DNA that changes the T at base 14 to a G: a) What would be mutated sequence of nucleotides in the corresponding codon in the mRNA and the anticodon in the tRNA? Is there any change in the corresponding amino acid in the protein? b) What is the name of this type of...
