What Does The Spatter Pattern?

Deoxyribonucleic acid, or DNA as it is most commonly known, is a strand of molecules found within the cell nucleus of all living things. It is called a “genetic fingerprint” because each is different to the other and everyone, apart from identical twins, have

Blood is a bodily fluid that transports oxygen and nutrients to the cells within the body. Blood has plasma that lets the different types of blood travel round the body. Plasma contains proteins that have different functions for the blood- clotting, transporting and defence organisms and osmotic organisations. The plasma carries the red blood cell which has a elastic membrane so it can fit through the small capillaries within the body. Red blood cells can be also known as erythrocytes they don’t have a nucleus when they are matured which gives a bigger space for oxygen, although as there is no nuclei the red blood cells can’t divide so they only live for around 120 days. Red blood cells gain their colour from haemoglobin, oxygenated blood which is known as arterial blood which flows through the arteries coming from the heart and

DNA is the genetic material that makes up the characteristics of all living organisms. While all human DNA is very similar in nature, there is just enough differences in

All living organisms have something called a ‘‘genome’. Genomes contain all of the DNA within that certain organism.The identity of an organism is defined by the DNA that is present in its genome. Humans are what is known as diploid organisms. The sperm from the dad have one set of chromosomes, and the egg in the mom has the

DNA molecules were unique to an individual with the exception of monozygotic twins. Due to

The blood contains the oxygen, platelets, nutrients, red and white blood cells, hormones which are all important materials for metabolism.

Each human being has something called DNA. DNA is described as genetics and an extremely long macromolecule that is the main component of chromosomes and is the material that transfers genetic characteristics in all life forms. DNA constructs of two nucleotide strands coiled around each other in a ladder like arrangement with the sidepieces composed of alternating phosphate and deoxyribose units and the rungs composed of the purine and pyrimidine bases adenine, guanine, cytosine, and thymine. Each chromosome consist of one continuous thread-like molecule of DNA coiled tightly around proteins and contains a portion of the 6,400,000,000 basepairs that make up your DNA.

There were two pieces of evidence that came into question with regards to blood spatter. In the 1956 trial Gerber, the coroner, claimed that an outline in blood on one of the pillows resembled that of a surgical tool but was unable to identify the surgical tool. Gerber would have concluded this observation by believing the bloodstain pattern was a transfer pattern. It was concluded however, that the result of the blood stain on the pillow came from another pillow overlapping it.

Blood is a mixture of liquids and solids. Blood contains plasma, serum, red blood cells, white blood cells proteins and more. Blood does not stay in liquid form for a long time after being exposed from your body, due to clotting. It clots a few minutes forming a dark red, gel-like substance that becomes more solid time passes. Blood clots can tell an attack was prolonged or the victim was bleeding for a significant period after being injured.

Bloodstain pattern analysis (BPA), known in the criminal justice field as blood splatter analysis, has been studied since the 1890s. Blood splatter, or bloodstain pattern constructional readings, is a technique that seeks to piece together the incident that caused an individual’s bleeding. Understanding blood splatter on a wall or various surfaces can be instrumental in formulating if a crime was committed and if the blood discovered at the crime scene can be used as evidence. The first documentation of blood splatter research occurred at the Institute for Forensic Medicine in Poland, by Dr. Eduard Piotrowski . During Dr. Piotrowski’s research and documentation period, where he used live bunnies to research blood splatter from head

Blood is made up of straw coloured plasma, the matrix, in which various types of blood are carried. Plasma is mainly water where substances are carried such as oxygen and carbon dioxide, nutrients such as glucose and amino acids, salts, enzymes and hormones. Also there is a combination of important proteins which help with blood clotting, transport,

Forensic science is a key aspect of Criminal Justice that helps rid the streets of lunatics and murderers. One of the most important fields of forensic science is blood spatter analysis. Under the Crime Scene Investigation, analysts gather the information that could eventually lead to a victim’s killer. Basic and complex information can be found when analyzing blood. We can learn what kind of weapon was used, the time of death of a victim and other important facts that can help a case. The pattern that the blood gives off give forensic scientists the tools that they need to help solve cases.

What is DNA? Is it these winding strands that look like ladders or is it what gives a person blonde hair and blue eyes? Actually, DNA is both of these things. DNA is a person’s genetic makeup–their hereditary blueprint passed on by their parents. It is a part of almost every cell in the human body. In each cell, a person’s DNA is the same; it stays the same throughout their lifetime. DNA is found in skin tissue, sweat, bone, the root and shaft of hair, earwax, mucus, urine, semen, and vaginal or rectal cells. The DNA found in a person’s saliva is the same as the DNA found in their blood. Parts of the DNA determine our physical characteristics, such as eye and hair color, height, and bone structure, but the

There are two types of twins. One type of twins, called identical twins, is exact clones of each other. They share the same DNA and were made from a single split egg. More research as been done regarding these types of twins as they are the more remarkable kind. Since they are a genetic match, nature plays the

Blood chemistry or blood test is identifying the different levels of chemical ingredients found in the blood. The analysis of these substances provides clues to a patient’s condition and the functioning of the major body systems such as, blood sugar levels, liver functions, essential nutrients etc. This helps doctors in diagnosing the patient’s conditions much easier and quicker.
