You’ve been called to the scene of a murder. The lock on the victim’s apartment door was broken, likely by a crowbar found in th
e doorway. The victim was found lying face down on the floor with a bullet in his back. Based on the condition of the apartment, it appears a struggle occurred between the victim and the murderer. There are several drops of blood located in the nearby kitchen, as well as a broken glass on the floor. Assuming this situation occurred in the late 1800s, which relatively new type of evidence would most likely be used to identify the killer? DNA samples taken from the hair and blood found on the floor
Motives of possible suspects based on information from the victim’s wife
Fingerprints found on the crowbar and on the glass
Information obtained after examining the bullet under a comparison microscope
i think its the "motives of possible suspects based on information from the victims wife"
<em><u>THIS IS HOW IT WORKED BACK THEN!!: they would First likely examine the bullet and then find out what gun model it belongs to then they would find the registered list of everyone with that gun and link possible suspects based off of that (which are related to the victim) thus would be looking for the killer based off of the victims life so the only option i see fit is the on i put in bold above ........ this is just my opinion though!</u></em>
DNA samples taken from the hair and blood found on the floor
Explanation:
Since there was a struggle between the victim and murderer, it is possible that the hair and blood found on the floor belong to the murderer. DNA samples taken from hair and blood could be used to generate DNA profiles using DNA fingerprinting technique which was developed in 1984.
By comparing the NA profiles made using DNA from hair and blood on the floor with DNA profiles of suspected killers, it is possible to identify the murderer.
Seedless nonvascular plants reproduce asexually through fragmentation. The parent organism are divided in fragments and these fragments or pieces grow into fully developed organisms. Plants like liverworts and lichens reproduce through this method.
Nucleic acids are polymers of individual nucleotide monomers. Each nucleotide is composed of three parts: a 5-carbon sugar, a phosphate group, and a nitrogenous base. Only two 5-carbon sugars are found in nature: ribose and deoxyribose.
