What is a major difference between dna polymerase i and dna polymerase iii?

(a) dna polymerase i synthesizes dna on leading strands and dna polymerase iii synthesizes dna on lagging strands
(b) dna polymerase i synthesizes dna on lagging strands and dna polymerase iii synthesizes dna on leading strands
(c) dna polymerase i repairs dna and dna polymerase iii synthesizes dna in the 3׳ to 5׳ direction
(d) dna polymerase i synthesizes dna in the 5׳ to 3׳ direction and dna polymerase iii synthesizes on lagging strands

(B) DNA polymerase I synthesizes DNA on lagging strands and DNA polymerase III synthesizes DNA on leading strands

Explanation:

Both the enzymes DNA polymerase I and DNA polymerase III involved in the process of DNA Replication with specialised functions. DNA polymerase I synthesize DNA on lagging strand where it degrades RNA primer and replace it with DNA. On the other hand, DNA polymerase III synthesize DNA from 5' to 3' end on the leading and lagging strand but stops at the RNA Primer.

 DNA polymerase I synthesizes DNA on lagging strands and DNA polymerase III synthesizes DNA on leading strands

Explanation:

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

the solute can move "downhill," from regions of higher to lower concentration, relying on the specificity of the protein carrier to pass through the membrane. this process is called passive transport or facilitated diffusion, and does not require energy.
