KARYOTYPING LAB INTRODUCTION The complete set of chromosomes in the body cell of a species is known as karyotype. Karyotype is a test to identify and evaluate the size‚ shape‚ and number of chromosomes in a sample of body cells. Any abnormalities such as extra‚ missing‚ or abnormal positions of chromosome pieces can cause problems with a person growth‚ development and body functions. Karyotype can be used to determine whether the chromosomes of an adult have an abnormality that can be passed on

imbalances. There are also inversions and translocations.These structural variations are the cause of a vast range of genetic disorders. Insertions are the addition of a sequence of one or more nucleotides between two adjacent nucleotides. They range in size from small‚ one base pair to large‚ a section of a chromosome.When a section of a chromosome is entered into another chromosome insertions can occur due to unequal crossover in meiosis. There are two types of insertions‚ an P nucleotide insertion

What are Cells‚ DNA‚ Genes and Chromosomes? In the human body there are 50 trillion cells. Cells structures the human body‚ takes in nutrients and covert it into energy. Each cell has a set of instructions that create a person identity and it is encoded into humans Deoxyribonucleic (DNA). Genes are a long strand of DNA. The long strands of DNA are organized into piece called chromosomes. Every human have 23 pairs of chromosomes. Chromosomes are organized to short segment of DNA called genes. A

Genetic counseling is the process that evaluates family history‚ ordering genetic test and evaluating medical records. Genetic counseling is a service that helps the people to translate scientific information into practical information. Genetic tests determine if there are gene-carrying traits or inherited disorders.
