2008). Mutations are permanent changes in the genetic material. A change in the DNA sequence of a gene 3 can alter the amino acid sequence of the protein coded by the gene. Mutations range in extent from a single nucleotide to a large segment of a chromosome (Campbell‚ 2008). Mutations may either be spontaneous‚ or induced by physical and chemical agents (Mendioro‚ et. al.‚ 2013). Mutagenesis‚ the creation of mutation‚ can occur in various ways. It could be

Introduction The objective of the care of the special child assignment is to study a child with special needs in their typical everyday environment. I will study the child in the pre-school/ Montessori room. I will watch him working with the Special Needs Assistance* (SNA) and his interaction with the other children in the room. In this assignment I particular looked at: • The child’s use of space‚ environment and language. • To observe the child’s motor movements‚ both fine and gross

independent assortment of chromosomes during meiosis. An interesting fact about ascospore arrangements is that there occurs no hybridization‚ and there are peculiar forms of cross over. Ascomycetes can also reproduce asexually by spores called conidia‚ which are spores that are dispersed by wind and are produced at the end of the hyphae. Another interesting fact about Sordaria is the ability to maintain a constant liner order‚ permitting the observer to detect the behavior of chromosomes during meiosis. The

driving. 2. The eyes of an experienced driver sweep into the curve several seconds before reaching it. 3. Colorblindness primarily affects males. The genes for red and green cones are on the X chromosome and males have only one copy of this chromosome. Females‚ on the other hand‚ have a second X chromosome that serves as a backup if something goes wrong with the first. About one man in ten is colorblind. How will this information affect you as a driver now and in the future? (2-3 sentences)

Eukaryotes are organisms whose cells are organized into complex structures by internal membranes and a cytoskeleton. The most characteristic membrane bound structure is the nucleus. This feature gives them their name‚ (also spelled "eucaryote‚") which comes from the Greek word referring to the nucleus. Animals‚ plants‚ fungi‚ and protists are eukaryotes. Microorganisms and all other living organisms are classified as prokaryotes or eukaryotes. Prokaryotes and eukaryotes are distinguished on the

1. Explain what must happen in order for Greg and Susan to have a child with O type blood and nail-patella syndrome. Greg needs to pass down his chromosome 9 which carry the alleles‚ n and i. Susan also has the n and I alleles on chromosome 9. If both these alleles from both parents are passed down‚ it will create the allele Nnii which produced the blood type O and nail patella syndrome. 2. Determine all possible parental and recombinant gametes produced by Greg and Susan. Greg’s parental
