Question

Students are modeling how genes produce proteins by using wooden tiles with letters to represent the genes. In this model, the words that the combination of letters produce represents the proteins. In this model, which of the following best represents a mutation?
1-Combining many different words to create a complete message
2-Creating any word that is spelled exactly the same way forward and backward
3-Changing one or more of the letters so that they spell a different word or no word at all
4-Making different words, with a certain number of letters, that have the same meaning

Answer 1

Answer:

3-Changing one or more of the letters so that they spell a different word or no word at all

Explanation:

Genes are segments of the DNA that encodes the synthesis of protein. However, changes called MUTATION occurs to genes. MUTATION is any change in the nucleotide sequence of a gene caused by mistakes during replication or induced. Mutations, depending on how it occurs, results in differing effects on the protein. It can cause the production of a different protein, it can cause no protein to be formed due to the fact that a stop codon was encountered, it can also end up not changing the sequence that holds information about the protein.

According to the question, wooden tiles with letters represents the genes. These wooden tiles are combined by the students in such a way that the words produced represents the protein. A mutation, as defined earlier, means a change in one of the letters (genes) that will cause their combination to produce a word that is different from originally planned (different protein) or no word at all (no protein).
