Question

If scientists can get a hold of a piece of someone such as what and can identify that person?

a) Hair
b) Blood
c) Skin
d) All of the above

Answer 1

Scientists can identify a person using DNA samples from hair, blood, or skin, as each individual's DNA is unique and can be used to pinpoint identity or familial relationships.

Step-by-step explanation:

If scientists can get a hold of a piece of someone, they can indeed identify that person, which could be through a) Hair, b) Blood, c) Skin, or d) All of the above. These samples contain DNA, which is a powerful tool used for identifying individuals due to its unique sequence in each individual, with the exception of identical twins.

Each human cell has 23 pairs of chromosomes comprised of DNA, including thousands of genes. These genes are responsible for determining the genotype and phenotype of an individual.

Thus, when forensic scientists or geneticists analyze these samples, they can compare sequences to confirm relationships or identify individuals at a crime scene. For instance, matching DNA at a crime scene with a suspect's DNA can implicate or exonerate the suspect. Similarly, DNA testing can establish paternity or maternal links in cases of adoption.
