Human Biology - Coursework Example When it comes to the number of chromosomes, the number of nucleus is still the same in mitosis but meiosis contains a haploid number of chromosomes. There is also no exchange of DNA between chromosomes in mitosis while in meiosis, there is at least one cross-over. Transcription is simply a process where genetic information from DNA is transcribed into RNA.This process is important especially when producing proteins.DNA proteins cannot be directly changed into proteins that is why translation to RNA is important. Darwin popularized the theory of evolution and process of natural selection where only the fittest specie would survive. Some animals have evolved and changed their physical features in order to survive the environment. Lamarck on the other hand is known for the Theory of Inherited Characteristics. He said that the off springs of animals would be the one to manifest adaptation to the environment as passed to them by their parents. There are four critical elements namely: variation, inheritance, High rate of population growth, and differential survival and reproduction. A fine example would be the some bacteria increasing resistance to drugs in order to survive. In Eukaryota we have mushrooms and other fungi. Eubacteria includes streptococci which cause strep throat infections and other disease causing bacteria. Helpful bacteria like yogurt is also an example.
