<h2>Application of radioactive dating</h2>

Explanation:

It is used to detect the relationship between two closely related organism that are found from ancient period of time.
It is also use to detect the age of a newly discovered fossil.
Not only in the field of archaeology,it also used in the field of geology, sedimentology, for studying different lakes.
Isotope of iodine is used in medical field, to detect the cancer cells.
The isotope of carbon is used to detect the release of carbon in the ecosystem to monitor the release of old carbon which is stored in the soil thus it helps to detect the climate change which is done by anthropologenic disturbance.

Many different types of mutations can occur within the body. An individual experiences a mutation that changes a base

Georgia [21]

Answer:

The type of mutation responsible for changing a base in the mRNA strand, without changing the coding aminoacid or protein, is called a silent mutation.

Explanation:

In a silent mutation occurs the change of a nitrogenous base in one of the codons that encodes an aminoacid, without changing the aminoacid or altering the structure or function of the protein to be synthesized.

In this type of mutations the change of the base does not mean the change of the aminoacid, because some aminoacids can be coded with more than one codon. In the case of Leucine, the codons that encode it are CUU, CUC, CUG or CUA, so even if a base changes, the final protein will be the correct one.

For the other options:

Missense: the change of the base in the DNA chain implies the change of the codon in the mRNA and of the encoded aminoacid, in that way a structural and functional alteration of the synthesized protein occurs.

Nonsense: the change in the nitrogenous base in the DNA leads to the coding of a termination codon, so that the protein is ultimately incomplete.
Insertion: in this case there is the addition of more nitrogenous bases to the DNA chain, with respect to the original one.
