The answer is A
Explanation:
Two classes of genes, oncogenes and tumor suppressor genes, link cell cycle control to tumor formation and development. Oncogenes in their proto-oncogene state drive the cell cycle forward, allowing cells to proceed from one cell cycle stage to the next.
Answer:
Horizontal gene transfer
Explanation:
Horizontal gene transfer or lateral gene transfer is when an organisms of different species can acquire a gene from a different one. This process is well understood in bacteria and is responsible for the appearence of antibiotic resistant bacteria. Bacteria can take DNA fragments through a process known as transformation, but this is less common in eukaryotes. Gene transfer agents like viruses could carry the gene from one specimen to the other. Another way could be Horizontal transposon transfer but the exact mechanisms behind it are still under research.
Answer:
it becomes clear that the bulk of DNA can be isolated from the nuclear fraction, The Three Roles of DNA are G, C, and T. Figure 2-1 shows the structures of the four nucleotides in DNA. There are two with pyrim-idine bases) that are the fundamental building blocks of DNA.
