deletion - deletions are mutations in
directions: the code below is very similar to the code on the front. however, mutations have
occurred. using the same procedure you used on the front of this page, decipher this mutated code.

Explanation:

1. Type of Mutation: The example at the top (CTDGAG to CTAG) shows a deletion (the "DG" is removed). For the other codes, we analyze the changes. In DNA, a deletion mutation removes one or more nucleotides. Here, the code sequences have parts removed (like fewer triplets or altered sequences), so this is a deletion mutation.
2. Relating to DNA Mutations: DNA is made of nucleotide sequences (like the triplets here). Mutations like deletions change the original DNA code (sequence) by removing nucleotides, just as the code here has parts deleted, altering the original "code" (similar to how DNA's genetic code is altered by deletions, which can change the resulting protein or genetic information).

Answer:

• Type of mutation: Deletion Mutation
• Explanation relation to DNA mutations: The code in the riddle represents DNA nucleotide sequences (triplets). Just as a deletion mutation in DNA removes one or more nucleotides (altering the DNA sequence), the code here has parts (nucleotides/triplets) removed, changing the original code—mirroring how DNA’s genetic code is altered by deletions, which can impact the resulting genetic product (e.g., protein) by shifting the reading frame or removing coding information.
