A researcher while working in vitro (outside cell) added helicase enzyme which resulted in the untwisting of the DNA helix. But

Answer:

Option B

Explanation:

Topoisomerase are the enzymes that help in correcting the underwinding of DNA. It act as a maintainer of DNA replication process by preventing the overtightning of the DNA double helix at the time of replication. The DNA helix which is infront of the replication fork is prevented from getting tight at the time of unwinding which is a problem arising due to the double-helical structure of DNA.

Hence, option B is correct

It seems that you have missed the necessary options for us to answer this question so I had to look for it. Anyway, here is the answer. Varicose veins seen in the superficial veins of the legs are unsightly and often treated by surgically removing them. however, even without these veins being present, the return of all blood toward the heart from the legs is not diminished primarily because <span>blood can still return via the deep veins. Hope this helps.</span>

Most species of cyanobacteria are enclosed in a _____.
Natali [406]

Answer: mucilaginous sheath

Explanation:

These algae are known as "blue algae" because of their pigmentation or "cyanobacteria" because they are prokaryotes. Microbiologists classify cyanobacteria in the realm of Eubacteria. They are the only prokaryote algae. The cellular organization is prokaryotic, without nuclei or organelles. Respiration takes place at the level of plasmalemma and thylakoids. In the center (nucleoplasm), cells contain their genome and circular plasmids. Cyanobacteria often also have a mucilaginous sheath common to many trichomes.

These organisms contain several carotenoid pigments, particularly myxoxanthophyll, which does not occur in any other algae group. Some cyanobacteria are strictly phototrophic, others are optional: they are phototrophic when in the presence of light, but may grow in obscurity using an organic carbon source. Others can use a source of organic carbon as well as inorganic carbon, but only in the presence of light.
