are very helpful to you as you can see. Last but not least are nucleic acids. They consist of DNA‚ RNA‚ ATP etcetera. A difference between DNA and RNA is that DNA is double stranded and RNA is single stranded. The monomer of it is nucleotides. The structure is made up of sugar‚ phosphate group and a nitrogen Functions include the DNA containing all of your hereditary information and RNA uses your DNA to make proteins. This

Chapter 4: Case Study: When radiation therapy kills. The concepts of ethics are illustrated in this chapter. Ethics is a concern of humans who have freedom of choice. Responsibility‚ accountability and liability are issues that are raised by radiation technology. In this case we see that the carelessness or laziness of the medical technician‚ the lack of training in the handling of the equipment (software)‚ also of the maintenance of the updates of the software can cause the life a person.

OBJECTIVES The Basis of Heredity 1. Explain in general terms how traits are transmitted from parents to offspring. An organism’s traits and appearance are controlled by specific forms of proteins contained in DNA. When gametes are formed‚ the male and female parents pass along their DNA into their respective gametes. Fertilization fuses the gametes and combines the genetic contribution of each parent into the new offspring. 2. Distinguish between asexual and sexual reproduction. Asexual Reproduction-A

Space Radiation Too Deadly For Mars Mission by Charles Q. Choi‚ Special to SPACE.com Date: 31 March 2008 Time: 10:00 AM ET Dangerous levels of radiation in space could bar astronauts from a mission to Mars and limit prolonged activity on the moon‚ experts now caution.However‚ more research could reveal ways to handle the risks that radiation poses to space missions.The magnetic field of Earth protects humanity from radiation in space that can damage or kill cells. Once beyond this shield‚ people

Data Analysis Does radiation affect the growth of seeds? If‚ plant seeds are exposed to microwave radiation‚ then the seeds will grow less than how a seed is usually grown. The independent variable was the amount of microwave radiation the seeds receive. The dependent variable was the growth of the plant seeds. Control variables were the amount of water (30 mL at a time)‚ the amount of light (11 hours each day)‚ and the amount of seeds. The control group was the non-microwaved seeds. The experimental

An adaptive radiation was defined by Schluter (2000)‚ as "the evolution of ecological diversity‚ within a rapidly multiplying lineage". Species can go through an adaptive radiation (involving a diversification of that species)‚ in response to having invaded a vacant ecological niche. It is thought the ability to do this‚ can be attributed to one or more key innovations developed by this species (i.e. the species has developed a new key innovation’‚ which makes it possible to invade new niche‚ that

Conclusion 3.2.1 1 Describe how the DNA code is translated into messenger RNA. DNA is translated into messenger RNA through transcription and translation. DNA is split through transcription and then it is translated to match into RNA. 2 How is the RNA molecule a “script” for the protein production process? RNA is a script for the protein production process because they set the RNA up to translate into a protein. 3 What is the function of hemoglobin in the body? Hemoglobin functions in the body by

The DNA Identification Act of 1994 authorized the establishment of a national index of: (1) DNA identification records of persons convicted of crimes‚ (2) analyses of DNA samples recovered from crime scenes‚ and (3) analyses of DNA samples recovered from unidentified human remains. In addition‚ it specified several standards for those laboratories that contribute profiles to the national index system‚ including proficiency testing requirements for DNA analysts and privacy protection standards related
