NEET BIOLOGY

Detailed explanation-1: -Actually, most of these viruses are found in oceans, where they attack bacteria and other microbes 3. It may seem odd that bacteria can get a virus, but scientists think that every kind of living organism is probably host to at least one virus!

Detailed explanation-2: -That produces a large number of free viruses and could be key to their survival. “There are 10 times more viruses in the ocean than there are bacteria, ” Morris said. “Understanding how these large numbers are maintained is important.

Detailed explanation-3: -Viruses are much smaller than bacteria and consist of a single-or double-stranded nucleic acid (DNA or RNA) surrounded by a protein shell called a capsid; some viruses also have an outer envelope composed of lipids and proteins. They vary in shape. The two main classes are RNA viruses and DNA viruses.

Detailed explanation-4: -Nearly 200, 000 different kinds of viruses swirl in the world’s oceans, according to a new study, Quanta Magazine reports.

Detailed explanation-5: -Virus capsids predominantly come in two shapes: helical and icosahedral. The helix (plural: helices) is a spiral shape that curves cylindrically around an axis. It is also a common biological structure: many proteins have sections that have a helical shape, and DNA is a double-helix of nucleotides.
