Types of DNA Technology

b) Label: Homologous chromososmes, sister chromatids, nonsister chromatids, chiasmata, synapsis, tetrad, centrioles, centromere, centrosome, metaphase plate, spindle fibers, microtubules, germ cell, gamete cells

Discoveries in DNA, cell biology, evolution, biotechnology have been among the major achievements in biology over the past 200 years with accelerated discoveries and insights over the last 50 years. Consider the progress we have made in these areas of human knowledge. Present at least three of the discoveries you find to be most important and describe their significance to society, health, and the culture of modern life.

b) How do the products of meiosis compare to the original cell? Think about chromosome number. (1 point)

Define the term crossing over. (3 points) During meiosis’ prophase the homologous chromatids exchange segments.

A) The genetic material in one eukaryotic cell is copied and distributed to two identical daughter cells.

(e) The largest DNA fragment on the gel belongs to the mother of Couple B and

gametes during meiosis in the F generation. The F can be thought of as having been formed

C. A chromatid is a chromosome that has been replicated but has not yet separated from its sister chromatid.

2. Which of the following is NOT one of the many ways that genes can affect behavior?

DNA is one of the most important pieces of evidence that a criminal justice agent can use in a court of law. There ae slim to no crimes committed that doesn’t have some type of DNA evidence left behind. Some DNA evidence could be, but not limited to, fingerprints, blood, hair, and any other bodily fluids. DNA is known as Deoxyribonucleic Acid, and is one of two types of molecules that encode genetic information (Medicine.net, 2017). DNA is characteristically unique to each person individually, unless they are a twin. DNA dictates a person’s look such as their eye color, blood type, height, hair color, skin color, etc. With this genetic information, intense testing can be done to find who may be connected to the genetic makeup of each stand

nant research, to achieve recombinant DNA. The gene that is the focus of this experiment and is

Advances in DNA technology has expanded greatly in the world of forensic science. In the past a vast number of crime scene evidence was not considered for analysis is now being tested. Trace DNA is more effective in this century when convicting a criminal than it was 20-30 years ago. Due to the consist improvement of DNA technology forensic scientist are able to put away criminals the correct way.

DNA, Deoxyribonucleic Acid, is the basic structure for all life, it is the blueprint, the instruction manual, on how to build a living organism. DNA is made up of four nitrogen bases, adenine, thymine, cytosine, and guanine which are connected by sugar-phosphate bonds. Through a process called Protein Synthesis, the nitrogen bases are the code for the creation of amino acids. Essentially, DNA makes amino acids, amino acids make proteins, proteins make organisms. This process has been taking place for much longer than scientists have been able to document. Those scientists are called geneticists and their field is genetics.

There are three types of ways to produce a clone first one is gene cloning and that creates a copy of the genes or parts of DNA. Reproductive cloning makes a copy of whole animals. Then Therapeutic makes embryonic stem cells. The most used is therapeutic cloning.

2) Some people refer to homeotic genes as the “tool kit” to make any animal form. A) Explain the reasoning behind this statement and provide support for it.
