Department of Biological Sciences ‚ and Department of Nutrition and Dietetics*‚ Messiah College‚ Mechanicsburg‚ PA 17055 Page 2 ABSTRACT This study investigates gene regulation and how environmental arabinose and/or glucose can interact with genotype to influence phenotypic expression of the Green Fluorescent Protein (GFP) gene inserted in the plasmid under the control of a promoter called the pBAD promoter. Bacterial cells are a common choice for in vivo replication of DNA of interest

Genes and Genetics 1. 2. each chromosome exists as two genetically identical chromatids attached to their centromere. Each chromosome appears as two chromatids attached to a centromere. In the first meiotic division chromosomes align in homologous pairs. Points of contact form between members of the same homologous pair. The points of contact or crossing over between members of a homologous pair are the chiasmata. 3. The homologous pairs move to the equator of the cell. Equal lengths of the

The F1 generation flies were crossed‚ and their progeny (F2 generation) produced 4 different types of phenotypes (wild type‚ cinnabar‚ brown and white) in the phenotypic

Life Span Perspectives There are many beginnings to the study of human development. The study of human developments is a science that strives to discern how people change over time (Berger‚ 2011). To do this‚ developmentalists study all types of people from different age groups‚ ethnicity‚ culture‚ background‚ nationality‚ income‚ and sexual orientation‚ among many other factors. To begin to understand this science‚ one must start by looking at what is being studied‚ some of the major theories

Functional groups are usually atomic groups that occur naturally within the organic molecule. They convene chemical properties to the perspective particle. Each organic molecule type hold a specific type of functional group. Functional groups in different biological molecules play a significant role in the bio-molecules formation such as protein‚ DNA‚ sugars‚ amino acids‚ lipids and carbohydrates. Functional groups include the carbonyl‚ methyl‚ hydroxyl‚ amino‚ phosphate‚ and sulfhydryl. These are

four daughter cells‚ each having one-half the normal number of chromosomes (23). Genes that code for a particular trait come in several forms or alleles. Genotype refers to the particular set of alleles an individual receives. Phenotype refers to an individual’s observable attributes. People with different genotypes may have similar phenotypes. Some traits involve only one gene locus and are called single-gene traits. The transmission of these traits from parent to offspring follows predictable
