Long stands of double helical DNA can fit into the nucleus of a single cell because DNA is specially packaged through a series of compaction events to fit easily within cell nuclei. Even though the length of DNA per cell is about 100‚000 times as long as the cell itself‚ it only takes up only about 10 percent of the cell’s volume. The DNA molecule‚ in order to condense‚ wraps itself around groups of histone proteins‚ and then the chromatin folds back on it‚ nucelosomes pack together to create a compact

Explain the mechanism of communication‚ control‚ and integration in the endocrine system. The Endocrine systems mechanism of communication is sending messages from the cells of the endocrine and nervous system to the cells in other systems by releasing hormones. The Endocrine systems control feature is part of negative feedback because it

Running Head: DNA Testing DNA Testing CRJ 311 Forensics Timothy Knox November 4‚ 2012 Thesis DNA testing has become a major part of forensic science. It helps in so many areas of life. Catching criminals‚ freeing the innocent‚ determining paternity of children‚ amongst other things‚ are just a few ways DNA testing helps. It has a few cons like the financial burden of it. But in the end it is worth it. Without DNA there would be many offenders roaming the streets‚ while hundreds of innocents

In my BIO 102 lab I have learned about the Microscope and Lab Safety‚ Sensory Organs (Eyes and Ears)‚ The Human Blood and Circulation‚ and Respiration. Once I first started this class this semester taught us about the Microscope and Lab Safety. According to google online dictionary a Microscope is an optical instrument used for viewing very small objects‚ such as mineral samples or animal or plant cells typically magnified several hundred times. We used this instrument to look at different types

The Scientific Method in Relation to Fingerprinting Although no one scientist is recognized as the inventor of the scientific method‚ its use in the scientific community believes to date back to 384-322 B.C. During this time‚ Aristotle recognized the importance of deriving reliable knowledge based on observation. As time progressed to the 1200s‚ Roger Bacon acknowledged the significance of the repeating cycle of observation‚ hypothesis‚ experimentation and verification‚ a scientific method that

DNA extraction and purification is an essential tool in understanding the biological basis and significance of a eukaryotic cell. Its role is pivotal to numerous scientific applications ranging from basic science research to applied research. Hence‚ DNA is found in all living organisms. Fragaria x ananassa‚ also known as a strawberry has been widely used as one of the many biological models in studying DNA structures due to its accessibility. Strawberries are octoploid which contain large genomes

AP Bio Lab Report Osmosis and Diffusion Introduction When a substance is released into an area‚ the random movement of its molecules results in a multitude of collisions. These collisions‚ in turn‚ lead to a dispersion of the molecules. The overall movement of the molecules will be from an area of high concentration‚ where there will be more collisions‚ to areas of low concentration‚ where the number of collisions will be much less. This process of dispersion will continue until there is no
