Which feature of the watson and crick model of dna structure explains its ability to function in replication and gene expression?

The correct answer is reciprocity or pairing of the bases.

Explanation:

The fact that bases are reciprocal to one another (thymine and adenine, cytosine and guanine) means that the same information contained in one strand is also found in the other one. This led to the fact that the DNA molecule is the one that carries genetic information.

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
