Forensic scientists are trying to find an exact dna match to a sample left at the scene of a crime. the sample from the crime scene has both a 900 bp and a 260 bp dna fragment. based on the suspect's profiles below, which one likely committed the crime? suspect i has 900 bp and 540 bp sized dna fragments suspect ii has 840 bp and 260 bp sized dna fragments suspect iii has 900 bp and 260 bp sized dna fragments suspect iv has 730 bp and 380 bp sized dna fragments a. suspect iii b. suspect iv c. suspect ii d. suspect i submit for grading save and finish later

Forensic scientists are trying to find an exact DNA match to a sample left at the scene of a crime. The sample from the crime scene has both a 900 bp and a 260 bp DNA fragment. Based on the suspect's profiles, suspect iii has 900 bp and 260 bp sized DNA fragments suspect.

Further Explanation:

In Forensic testing, a scientist uses the sequence of the DNA to identify an individual for official reasons. But, forensic testing is not used to identify gene mutations related to any disease. This kind of testing helps to identify the criminal. Gene testing is not considered as foolproof as there are many possibilities fault in it based on the procedures used and the situation of the sample. The statistical probability is used to determine the probability of paternity, the relationship of any kind, etc. among two individuals. Usually, 99% or higher percentage of probability is considered conclusive, and thus it gene testing cannot be considered as foolproof.

The table given below will explain the identification method used by the forensic expert. The sample is matched with the suspect three because the DNA fragments are of the exact size.

4.) metal

"-the movement of carbon from the nonliving environment into living things and back to the environment

-carbon is the essential component of proteins, fats, and carbohydrates (which make up all organisms)

-carbon exists in air, water, and living organisms

-producers convert carbon dioxide in the atmosphere into carbohydrates during photosynthesis

-bacteria in the atmosphere cycles through the system in filtration units

-in cellular respiration, carbon is released back into the atmosphere as carbon dioxide

-some carbon is stored in limestone (forming one of the largest "carbon sinks" on earth)

-largest carbon reservoir on earth= limestone

-carbon stored in the bodies of organisms as fat, oils, or other molecules may be released into the soil or air when the organism dies

-this may form deposits of coal, oil, or natural gas (fossil fuels, which increased the atmospheric carbon dioxide)

-fossil fuels store carbon left over from bodies of organisms that died millions of years ago

-they are located in the surface of earth, deep within the earth and beneath the ocean floor."
