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

this untwisting led to strain ahead of the replication fork. Which enzyme can be added to correct this problem?
Nuclease
Topoisomerase
Telomerase

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

The type of contraction in which the muscle fibers do not shorten is called
Korolek [52]

Answer:

Isometric contraction

Explanation:

The length of the muscle is changed during contraction only when the muscle tension during contraction can outstand the resistance exerted by the object to be lifted.  

During isometric contractions, the muscle tension is not sufficient to exceed the resistance of the object. Hence, there is no change in the length of the muscle. The isometric contraction does not bring about any body movements.

Answer all 3 wuestions for 25 points and brainliest
mixer [17]

Answer:

17. C " TAAGCTG". It would be the replication strand because A always pairs with T and C always pairs with G, so replication strands just have the opposite base as the original strand  

18. Transcription is the name given to the process in which DNA is copied to make a complementary strand of RNA. RNA then undergoes translation to make proteins. The major steps of transcription are initiation, promoter clearance, elongation, and termination.

19. Straight hair is controlled by a recessive allele because as you can see the one where is not shaded is the one that has the most. There are only 1 shaded circle or square, out of the 12 other circles or square that is not shaded. This means that it is the recessive allele because people are less prone to getting straight hair, as you can see in that diagram.

Answer:

Letter A represents the greatest potential energy.

Letter C represents the least potential energy.

Letter C represents the greatest kinetic energy.

Letter A represents the least kinetic energy.

Letters A and C represent an equal amount of both potential and kinetic energy.

Explanation:

Potential energy is a put away energy that relies on the overall situation of different pieces of a framework. A spring has progressively potential energy when it is packed or extended. A steel ball has more potential energy raised over the ground than it has in the wake of tumbling to the Earth. In the raised position it can do more work. Potential energy is a property of a framework and not of an individual body or molecule; the framework made out of the Earth and the raised ball, for instance, has progressively potential energy as the two are more distant isolated.\

Kinetic energy is a type of energy that an article or a molecule has by reason of its movement. In the event that work, which moves energy, is done on an item by applying a net power, the article accelerates and along these lines increases kinetic energy. Kinetic energy is a property of a moving item or molecule and depends on its movement as well as on its mass. The sort of movement might be interpretation (or movement along a way starting with one spot then onto the next), turn about a pivot, vibration, or any blend of movements.
