Alfred Hershey and Martha Chase used radioactive isotopes to prove that DNA was the carrier of inherited material. They laid the foundation for Watson and Crick to prove that the double helix structure suggested the copying mechanism that allowed for DNA to function as a hereditary material!
Mitochondrion are the powerhouses of all cells. Obviously, you would need lots of power to move the muscles in your body. Therefore, muscle cells (myocytes) have a relatively large amount of mitochondria in order to provide enough energy to move the muscle, an essential life process.
This article from enotes explain how it interacts with ribosomes.
Its main job is to break down glucose into ATP (energy that the cell can use). The mitochondria does work with other cell organelles in that the ATP is dispersed throughout the cell to power the function of the cell. Specifically, the Ribosomes use the ATP to produce proteins in a process known as protein synthesis.
Mendel studied a total of seven traits of garden peas. His experiments were successful because the pairs of factors for the traits he studied were on seed shape, flower color, seed coat tint, pod shape, unripe pod color, flower location, and plant height
The allele would be called codominant
When a dominant and recessive allele exist in an organism, only the dominant allele will be expressed. Dominant allele always mask the recessive because the gene code a protein while recessive gene doesn't. When both gene code a protein, they will be codominant and both gene will be expressed. The result could be a mixed effect. In this case, the purple is mixed color of red and blue.
