Answer: DNA can be used to identify criminals with incredible accuracy when biological evidence exists.
Explanation:
In cases where a suspect is identified, a sample of that person's DNA can be compared to evidence from the crime scene. The results of this comparison may help establish whether the suspect committed the crime.
No Problem at all!

Answer:
A) Brain genomic library and muscle genomic library.
B) Brain genomic library and muscle genomic library - overlap completely.
Human brain cDNA library, and a human muscle cDNA library and other library is partially overlap.
Explanation:
A) The genomic library contains the whole genome content of the organism whereas cDNA library contains the coding genome of the organisms. Brain genomic library and muscle genomic library will constitute the all the genomic sequences of brain and muscle. The cDNA library is prepared from the mRNA and the coding regions are present in this library.
B) The overlapping in the genome library might occur due to the common sequences present in the genome. Brain genomic library and muscle genomic library might completely overlap with each other as they have more sequence common among each other. All the other library may be partially overlap with each other as they have some common DNA sequences and neither library can have unique sequences.
Answer:
1. Radiometric dating
2. Relative dating is used to determine the age of fossils or rock layers by by comparing it to similar rocks and fossils of known ages.
3. The youngest rock layers are at the top and the oldest are at the bottom, which is according to the law of superposition.
4. Tribolite and Pecten fossils
Fossils are used to determine the ages of rock layers. Index fossils are the most useful in determining relative aging. Index fossils are of organisms that lived for a short period of time. An index fossil allows a scientist to determine the age of the rock it is in. So if they are found in a particular age, it means they belong in that age.
5. Scientists commonly use radioactive dating methods by using radioactive decay cloak of certain elements such as potassium or carbon to date fossils or rocks.
6. Law of superposition because in terms of finding the age of the rock as an object, all that needs to be identified are the layers of the rock.
7. The nuclear decay of radioactive elements are a process that behaves in a clock-like fashion which makes it a useful tool for determining the exact age of fossils or rocks.
