Answer: The answer is helicase. This enzyme allows of the unzipping of the double helix DNA to form the replicating fork. They use ATP hydrolysis to break the hydrogen bonds between nucleotide bases. This comes before binding, on the DNA, by replication enzymes such as DNA Polymerase III.
Explanation:
I'm Smart
1.) D- phloem is Bi-directional and can flow upward or downward
2.) C- it transports the water from the roots to the stems and leaves
3.) A- capillary action <span>is the ability of a liquid to flow in narrow spaces without the assistance of, or even in opposition to, external forces like gravity, so it can flow upward through the tissue
4.) B- It conducts the sugar and other metabolic materials downward from the leaves
5.) A- </span><span>The roots </span>have a type of cell called a root hair cell - these project out from the root into the soil. The water<span> absorbed by the root hair cells passes through the plant in xylem tubes, and eventually reaches the </span>leaves<span>.
6.) A- It transports </span> water<span> from roots to shoot and leaves, but it also transports some </span>nutrients. It is Uni-directional though and can only flow upward.
Hope this helps! Good luck
