The enzyme responsible for separating the two strands of DNA in a helix so that they can be copied during DNA replication.Explanation:
Explanation:
Hormone production and release are primarily controlled by negative feedback. In negative feedback systems, a stimulus causes the release of a substance whose effects then inhibit further release. In this way, the concentration of hormones in blood is maintained within a narrow range.
Answer:
e) B and C
Explanation:
Allosteric regulation occurs at these points where the concentration of the substrate and/or products is important for the activation and inhibition of the enzyme.
Answer:
Antibiotics are simply chemicals that kill prokaryotic cells but do not harm eukaryotic cells. They are natural chemicals produced by fungi and bacteria that act to control their bacterial competitors. For example, streptomycin stops protein synthesis in prokaryotic cells by binding to their unusual ribosomes.
Explanation:
Sorry if this makes no sense. Basically, the antibiotics will harm/kill cells like the prokaryotic cell, but it won't harm or kill any human cells that are essential. They'll kill bacteria, though. The chemicals in the antibiotics aren't compatible with the ones in the prokaryotic cell, so it'll kill it.
Uranium-235 is the answer
