True or false: "The change from a T to a C at position 3 caused all of the changes that exist between the cichlid and coelacanth/frog." Explain your answer.

The statement " The change from a T to a C at position 3 caused all of the changes that exist between the cichlid and coelacanth frog" is false.

Point Mutation:

These are the mutations that are caused by the exchange of one nucleotide.

This can be a harmful mutation.

Genetic diversity can be caused by other types of mutation also. For example - deletion mutation.

Therefore, the given statement about cichlid and coelacanth frog is incorrect.

The above statement is false.

Explanation:

As we can infer from the question, Thymine is being replaced by Cytosine at position 3 of a genetic sequence. This means that only a single change is being made in the genetic sequence. This change will cause a faulty protein to be formed. The faulty protein will be associated with this genetic sequence.

Hence, not all of the changes existing between the cichlid and coelacanth/frog will be associated with this single base change.

However, instead of replacement of C with T, if an addition or deletion of a base might have occurred, then the entire genetic sequence would have been altered causing many changes.

ionic bonds are two oppositely charged ions that attract. a sodium ion has a 1 positive charge; a chloride ion has a 1 negative charge. sodium and chloride have oppostive charged ions that attract which forms an ionic bond. a chemical bond formed when two atoms share electrons is called
