Unique or damaging plate edges cause volcanoes. As the more thick plate subducts, it will dissolve at profundity and the water is driven off, will bring down the liquefying purpose of the overlying mantle wedge, this will make a kind of magma. Volcanic Island Arcs are framed at maritime dangerous plate edges. The hot, light magma, is less thick that the encompassing rock so will ascend to the surface, and will gather underneath the plate that hasn't been subducted. It will then, under expanded weight eject under the ocean. More than thousands of a great many years, it will continue emitting, to shape islands.
Answer:
2) CAG - TTC - ACG mutates to CAG - TTC - ACC - ACG
Explanation:
Insertions are mutations in which extra base pairs are inserted into a new place in the DNA. The number of base pairs inserted can range from one to thousands!
In option no. 1: We see that there is not addition of a single or more than one base, but the new base sequence is different from the original sequence at three places i.e: TTA - CAC - G
In option no. 2: The insertion of three bases ACC has been made exactly after TTC, the whole sequence and arrangement of bases remain same except this insertion.
In option no. 3: The first base of the sequence T is replaced with A, and all other sequence is same. This type of mutation is called substitution in which one base is replaced by other.
In option no. 4: The last base of the sequence C is deleted, and is not present in new sequence. This type of mutation is called deletion in which a base is removed from the sequence.
Conclusion: Therefore, the best option is 2, in which whole codon is inserted in the DNA base sequence.
