In what ways is the structure of mRNA similar to the DNA

Explanation:

1) Both have pentose sugar (sugar is slightly different in DNA being a deoxyribose but still a pentose sugar)

2) Both mRNA and DNA have sugar and phosphate backbones, and nitrogenous bases.

3) mRNA and DNA have Adenine, Guanine, and Cytosine as similar nitrogenous bases.

4) Both are crucial in central dogma of life (this is the process of DNA-->mRNA--> protein) or you could say both are crucial to produce an enzyme or protein...

the list goes on and on

answer: - few nutrients

high pressure

low temperatures

explanation: 1. few nutrients:   open-ocean zone is located way far from the land, which is the main source of the essential nutrients.2. high pressure: pressure increases by 1 atmosphere for every 10 meters increase in depth.3. ample sunlight: a large fraction of the sunlight is reflected back to the atmosphere from the sea surface. 4. varying salinity: below the thermocline, the water is isolated from the atmosphere so the salinity remains stable over the year.5. low temperatures:   the temperature of open-ocean zone ranges from a low of -2°c to an average of 17°c
