Answer:
Chromosome structure consists of a long arm region and a short arm region connected at a central region known as a centromere. The ends of a chromosome are called telomeres. Duplicated or replicated chromosomes have the familiar X-shape and are composed of identical sister chromatids.
Explanation:
<span>When cells divide uncontrollably, then there is a huge number of them and they take up most of the space in the body. Thus, lumps start to appear on and in a person's body, on organs and skin, and these lumps often represent cancer. So, uncontrollable division of cells can lead to cancer. Hope this helps. Let me know if you need additional help!</span>
Answer:
E) horizontal gene transfer
Explanation:
Horizontal gene transfer can also be referred to as lateral gene transfer. It is the transmission of deoxyribonucleic acid (DNA) between different genomes.
Horizontal gene transfer has been shown to occur between different species, such as between prokaryotic and eukaryotic organisms.
Horizontal gene transfer is made possible by the existence of genetic elements, such as plasmids, transposons, and bacteriophages (bacteria that infects viruses).
Answer: Option C.
GAL80 would be able to bind to GAL4, and transcription of the genes involved in galactose metabolism would be repressed.
Explanation:
Gal 3, Gal 80 and Gal 4 are form of proteins which participate in metabolism. They constitute a galactose-responsive switch for the GAL genes When galactose is absent, Gal 80 bind to Gal 4, masking the Gal4AD prevent gene transcription and prevents Gal4-mediated promoter activation
