performed a genetic transformation through the process of gene transfer. Gene transfer involves the insertion of a gene into an organism. The gene to be inserted is usually contained in a plasmid‚ which is relatively small‚ circular non-chromosomal DNA molecule typically found in bacteria. Once the plasmid containing the gene is inserted into the organism‚ it is absorbed into the organism’s own genetic code. After this occurs‚ the newly introduced gene begins coding for proteins‚ giving the organism a new

Sex linked genetic disorders Fragile x syndrome Sex-linked traits are genetic characteristics determined by genes located on sex chromosomes. Genes are pieces of DNA on chromosomes that carry information that are responsible for inheriting traits. Different forms of the same gene are called alleles. One allele for a certain trait is inherited from a mother and one from a father. These traits are passed down from parent to their offspring by sexual reproduction. Fragile X syndrome (FXS) or Martin-Bell

area and separated physically from other populations of the same species. The genotype of a population is called its gene pool and consists of all of the alleles present in the population members for all of the genes found in that species. Evolutionary change occurs when there is a measurable change in the population’s genotype through time. Alleles are alternative versions of gene. An allele is said to be lethal if it directly causes death of the organism. A lethal recessive allele must be inherited

HUMANS Human gene therapy Gene therapy is the use of DNA as a drug to treat disease‚ generally by incorporating the DNA into the patient’s chromosomes and generally by seeking to have the DNA express a protein. The most common form of gene therapy involves using DNA that encodes a functional‚ therapeutic gene to replace a mutated gene. Other forms involve directly correcting a mutation‚ or using DNA that encodes a therapeutic protein drug (rather than a natural human gene) to provide treatment

a population as a result of a selective force Hypothesis The starting ratio of HbA to HbS is 3:1; in a typical population‚ the Homozygous Dominant Gene would become the standard‚ but because carrying the Heterozygous version of the allele has an advantage to fighting Malaria it will become the dominant Allele for the population. The HbA/HbS gene will thrive because it helps in the fight against Malaria‚ turning a typically negative trait into an advantage. The Homozygous Recessive will disappear

of metabolism and synthesis. Alleles are alternative forms of a gene and genotype refer to a specific allele like hair color‚ height‚ skin tone‚ etc. These observable traits are the phenotype. Phenotype is the resulting characteristic of an encoded genotype; it is what we can see‚ it’s the physical appearance of an organism. Genotype defines what will be the phenotype. 1Say for example‚ eye color. This is controlled by a single gene‚ but with several alleles. Example: Phenotype Genotype;

last few decades‚ and as long as many adults can remember‚ the view of gene inheritance has been written in the four letter language of DNA. Genetic mutations and re-combinations have driven most descriptions of how phenotypic traits are handed down from one generation to the next (The American Association for the Advancement of Science). Researchers and physicians attempted to untangle and discover the clues that suggested gene function could be altered by more than just changes in sequence (Weinhold

Genes are the building blocks of life. They uniquely define each and every one of us‚ from our hair color to our ability to fight disease. For the past few decades‚ the study of genetics has given scientists an ability that we as a species never had before-- the ability to directly modify our genetic makeup. With this scientific breakthrough‚ the possibilities are endless with real world implications. On a darker note‚ this also means that genetic modification has the ability to adversely affect

Our genes lead back to our ancestors who roamed the earth long before our existence. Some of us may have gotten our hair color from them or possibly our attitude‚ but have our ancestor’s trauma been passed on to us as well? It’s a question that’s been brought up over the years‚ while some people say it’s a myth the answer lies in the hands of science. Good afternoon Teachers and Classmates‚ today I will be presenting my speech on how trauma can be passed on through genes. A study was done at New

Introduction: Genetic Diversity: Every individual has a unique genotype. This is equal to the combination of alleles of all its genes. The greater the number of genotypes in a population‚ the greater the genetic diversity. Genetic mutations produce new alleles of genes that increase variation- Gene mutation are permanent changes in nucleotide sequence in codons of the gene/ produced when DNA replicates/ alters the AA sequence in the polypeptide and therefore the structureand function of the polypeptide
