Some Discoveries about DNA DNA is made of deoxyribose sugar, phosphate, and four nucleotides (A, G, C, and T). DNA was originally isolated from white blood cells. X-ray diffraction of the DNA molecules shows that it is a helical structure. Adenine pairs with thymine and guanine pairs with cytosine in any sample of DNA. DNA, not proteins, carries genetic information. Match the following scientists with their discoveries listed above.

Virus

Viruses are infectious microscopic agents that can only reproduce in live cells of animals, plants, or microbes and are smaller than bacteria. Vertebrates, invertebrates, plants, protists, and fungi are among their many hosts. Viruses are unable to multiply on their own due to the lack of necessary cellular machinery, but they can guide the cell machinery of a host to make additional viruses by infection. The virus enters and attaches to a particular host cell, injects its genetic material, and reproduces by using the host’s genetic material. Viruses cause infection by taking entry into the host cell and using the host cell’s enzymes and raw materials to multiply.
