While genes have potential to modify behavior, behavior can also modify genes. How do genes impact this process? How do genes determine the traits of an organism? How does the Chromosomal Theory of Inheritance helped to advance our understanding of genetics?

How does the structure of DNA determine our characteristics? How does DNA lead scientists to better classify organisms? How do the bases bond together in DNA? What is the DNA organization? How is it related to gene expression? How does the DNA of prokaryotic cells differ from the DNA of eu...
DNA Functions Scientists knew that the material that makes up our genes must do two things: Give instructions for building and maintaining cells Must be able to be copied each time a cell divides so that each cell could contain identical genes Scientists eventually discovered that DNA is made of...
How many genes control a given trait? And are genes with defined knockout phenotypes affecting a given trait the same genes that also underlie population-wide variation in that trait? A new study in Drosophila melanogaster has some surprising answers. How many genes control a given trait? And ...
How Do Recessive Traits Occur? When an individual has two recessive alleles, the phenotype is the recessive trait. For example, let's suppose that there are two versions of a gene, or alleles, that determine whether or not a person can roll their tongue. One allele, the dominant one, is...
DNA is found in the nucleus of every human cell. The information in DNA: guides the cell (along with RNA) in making new proteins that determine all our biological traits gets passed (copied) from one generation to the next The key to all of these functions is found in the molecular ...
By locking together traits that work well together, supergenes provide striking evolutionary advantages. But they can also be costly because they make it nearly impossible to purge bad mutations
Climate change influences how organisms live and function in their environment. Investigating how organisms adapt is essential for accurately predicting their survival, and tracking genomic(基因组的) changes helps researchers determine the lasting effects of the changing environment. Copepods, a dominant co...
Male Cannabis Plants Do Not Produce Bud There is no way to determine the gender of a plant initially, just by looking at the seeds, or even by looking at young plants. Both male and female cannabis plants look exactly the same until they start flowering. There used to be myths and trick...
