An error in cell development results in forty-seven chromosomes rather than the usual forty-six. There are three major types of Down syndrome. About ... Read More
A Study on Cancer Metastasis and the Innovative Technology Platform, Combinatorial Genetics En Mass (CombiGEM) (4199 words, 18 pages)
ABSTRACTCancer metastasis is the major cause of death in patients with solid tumors, but our understanding of its molecularand cellular determinants remains limited.

An Experiment on the Dominant/Recessive Parents of Barley Plants (1583 words, 8 pages)
Genes are a section of DNA that is contained in chromosomes. They are what determines the genotype, the genetic makeup, and phenotype, the physical appearance, of an organism.

An Experiment to Examine the Effects of Genetic Drift and Selection Pressure to Allele Frequencies (1600 words, 6 pages)
AbstractIn this experiment we examined how genetic drift and selection pressure effected allele frequencies along with other factors like original population size and allele fitness. We used Python to examine allele frequencies in certain populations and run simulations over multiple generations. We found that genetic drift has a greater effect ... Read More
The Importance of Race Consciousness in Political Blackness (1254 words, 5 pages)
In considering the argument between expressing deracialization or blackness in the black political world, history serves as a model for where each type of expression leads us.

A Report on Transgenerational Epigenetic Inheritance, the Transmittance of Information between Generations of Living Organisms (513 words, 3 pages)
Transgenerational Inheritance SummaryIn this article, it talks about non-DNA sequence. One must first understand that DNA is put together randomly through replication.
