DNA replication is a biological process that occurs in all living organisms and copies their DNA; it is the basis for biological inheritance. The process starts when one double-stranded DNA molecule produces two identical copies of the molecule. The cell cycle (mitosis) also pertains to the DNA replication/reproduction process. The cell cycle includes interphase‚ prophase‚ metaphase‚ anaphase‚ and telophase. Each strand of the original double-stranded DNA molecule serves as template for the production

Biology 1308 Instructor Childress June 22‚ 2012 Introduction This unusual case is based on a true story of a woman named Lillian‚ whose children were almost taken from her because her DNA profile indicated that she was not the mother of her children. The test revealed each child shared half of their DNA markers with their father‚ but only twenty-five percent of their DNA matches their mother. Our team will attempt to determine why this mother’s DNA profile does not

The amazing advances in health science‚ DNA is transforming the way in which criminal investigations and trials are carried out. DNA evidence and its importance can rest on a single fact: Every individual’s DNA is unique. A person’s DNA profile can be used similar to a fingerprint to link suspects to crime scenes and its victims. DNA profiling—which is also called DNA fingerprinting or even DNA typing—has been responsible for overturning verdicts and saving innocent people from execution. The process

Animals make some molecules unique to them 1) Galactose (monosaccharide) from glucose 2) Lactose (disaccharide) Glu‐Gal found in milk 3) Solid lipids (not oils) solid at room temperature 4) Glycogen‐ chains of glucose used for energy storage Synthesizing Polymers 1) Dehydration synthesis a. monomers join together into polymers while losing water molecules. This process is carried out by losing (‐OH) from one of the monomers and (H) from another monomer. The two unstable monomers join together‚ and the (‐OH) and (H) combine forming water

Something new was also used in this case‚ dog DNA. During the investigation‚ police learned that Taylor had been walking his dog around the time Leanne’s body was placed in the woods. Forensic examiners found dog hairs on Leanne’s body. The dog hair DNA sample was sent to a university in Texas. It produced a partial profile for a dog. However‚ this was not able to be used against John Taylor because he had killed this dog before the evidence was found. The dog had been buried‚ in Taylor’s back garden

DNA Transcription The process of transcription is where a copy of a gene is made within DNA to use as RNA. It is located in the nucleus of eukaryotes and in the nucleoid of prokaryotes. DNA stores information encoded in a genetic code. The code consists of four letters and they are T (thymine)‚ G (guanine)‚ A (Adenine)‚ and C (cytosine). One gene codes for on protein. RNA is a molecule that copies information that is coded in another genetic code. This code also consists of the same four
