Answer:
B) Polymerases can only synthesize in the 5' to 3' direction
Explanation:
The leading strand's directionality is 3' to 5', so polymerase has no problem with replicating this one. But the lagging strand has the opposite directionality, so the polymerase must work in the opposite direction of the replication fork.In consequence, the replication process undergoes periodic breaks, and the enzymes have to stop and start again while helicase separates both strands, resulting in the polymerization of okazaki fragments.
Answer:
4. halophile
Explanation:
Haloarchaea are extremophile microorganisms that <em>require high salt concentrations to grow (up to 10%).</em> This means that they have affinity (phile) for salt (halo).

Question #1
<span>Which of the following is NOT a characteristic of all life?
</span>
Your correct answer would be the "ability to move". Not all thing's in life can move. Just think of some other living thing's that does not have this.
Question #2
<span>Which of the following is the function of the Endoplasmic Reticulum?
</span>
Based on my information, the function of this would be of that it produces proteins
Global winds refer to the pattern of air movement all around the globe, and they result from the fact that the Earth receives unequal heating from the sun. Not only does the tilt of the Earth's axis mean that different parts in the planet receive desperate amounts of sunlight, but the oceans and lands also heat at different rates. The imbalance in temperature makes heat move toward the poles, both in the wind and in ocean currents. When horizontal variances in air pressure take place as a result, wind occurs.
Answer:
d. Estrogen will bind to a receptor protein that enters the nucleus and activates specific genes.
Explanation:
Estrogens are small lipophilic molecules synthesized from cholesterol. This steroid hormone (estrogen) is able to directly enter into the cell nucleus to bind with their corresponding receptors. Subsequently, estrogen-receptor binding stimulates these receptors to form dimeric structures that bind to DNA and thus activate gene expression. Estrogen receptors interact with DNA and activate gene expression through zinc finger domains composed of four (4) cysteine residues surrounding a zinc atom.
