BIOLOGY I TUTORIAL 2 BASIC MOLECULES OF CELLS II Student’s Guide: At university level, the tutor facilitates student learning without spoon-feeding. Therefore, you are expected to: • Read your textbook, attempt the questions before the tutorial • You may enter the class and sign your attendance after showing your tutor that all tutorial questions have been completed; even if you don’t know how to do, write something - you’re not advised to leave answers blank in the finals

Vertical gene transfer is the transfer of genetic material during cell division. Horizontal gene transfer, on the other hand, is the transfer of genetic material between different species of bacteria; three types are found. Conjugation is the transfer of DNA by direct contact with the cell. Transformation is the uptake of genetic material from the surrounding. Transduction is the transfer of genes via bacterophages. Two kinds of bacterial transductions can be found: generalized and specialized. Viruses

Associate Program Material DNA Worksheet Answer the following in at least 100 words: 1. Describe the structure of DNA. DNA nucleotide bases consist of a particular code and specific strands of this code are termed genes. A gene will code for particular proteins which will end in a specific trait. The base pairing in a DNA molecule is specific: Adenine always pairs with Thymine and Guanine always pairs with Cytosine. A gene segment from DNA will give the directions necessary to build

HUMAN GROWTH AND DEVELOPMENT Interaction of Nurture and Nature (Concept, Distinction among Growth, Development and Maturation) Determinants of Growth and Development 1. Heredity (nature) The process of transmission of traits to the individual from parents to offspring through germ cells consisting of chromosomes and genes. Chromosomes – usually in pairs and each carries the genes which are the true carriers of hereditary traits. Types of Genes: a.) Dominant gene – a gene that is phenotypically manifested

Genetic Enhancement on the Human Genome The debate on whether human genetic engineering should be researched and used as the main alternative solution to disease have been going on since the creation of the "human genetic engineering" phenomenon. The ethical question is clear: should money be invested in human genetic engineering and should we research it at all, even if it is formally criticized by all monotheistic religions? The ethical principles in conflict are beneficence (people with fatal

Eugenics: Health Benefits 1 Running Head: EUGENICS: HEALTH BENEFITS AND THE FUTURE Eugenics: Health Benefits and the Future Abstract The study of eugenics is propelling the world quickly into the future. Eugenics is the study of genetically engineering enhanced humans. This genetic engineering is done through modification of certain traits on an embryonic level, to create a heritable trait. Once modified, these traits will be passed on to the offspring of this

subjected to genetic engineering. The two main methods employed in genetic engineering are Recombinant DNA Technology as well as Reproductive Cloning. The first case involves the scientist combining genetic materials from different organisms. This is based on the fact that DNA molecules from all organisms be it plant or animals have similar chemical composition. The resulting DNA sequence from recombinant DNA technology can be planted into any organisms with no biological implications apart from the intended

PSY 240 Genes and Addiction Assignment In the study ‘Associations and Interactions between SNPs in the Alcohol Metabolizing Genes and Alcoholism Phenotypes in European Americans’, Sherva, Rice, Neuman, Rochberg, Saccone, and Bierut search for a correlation (a statistical measurement of the relationship between two or more variables) between two alcohol-related phenotypes and SNPs (single-nucleotide polymorphism) in 17 genes involved with alcohol metabolism. Alcohol metabolism is a process through
