Getting rid of c-section belly fat is important, but so is the time you spend with the person who caused the c-section in the first place! Your baby! Take care of yourself, certainly, but don't overdo it. If you need to obsess over something, obsess over your baby.
Transposable elements (TEs), also known as jumping genes , are DNA sequences that move from one location on the genome to another.These elements were first identified more than 50 years ago by geneticist Barbara McClintock of Cold Spring Harbor Laboratory in New York.he former elements are known as retrotransposons or class 1 TEs, whereas the latter are known as DNA transposons or class 2 TEs. The Ac/Ds system that McClintock discovered falls in the latter category. Different classes of transposable elements are found in the genomes of different eukaryotic organisms (Figure 1).
Discovering Addiction Genes. Many genes with roles in addiction were identified with the help of animal models, especially mice. Because the reward pathwayâand many of the genes that underlie itâfunctions in much the same way in mice as it does in people, mice are leading the way in identifying addiction genes. When researchers discover a gene that plays a role in addiction in a model organism, such as mouse or fruit fly, they can then identify the counterpart gene in humans by looking for similar DNA sequences. To the right, you will find a sampling of some of the genes suspected to play a role in addiction, many of which were identified first in animals. 1  The A1 allele of the dopamine receptor gene DRD2 is more common in people addicted to alcohol or cocaine.
