DNA gyrase is an essential bacterial enzyme that catalyzes the ATP-dependent negative super-coiling of double-stranded closed-circular DNA. Gyrase belongs to a class of enzymes known as topoisomerases that are involved in the control of topological transitions of DNA. Hope this helps! :3

Answer: Introduce negative supercoiling of circular DNA in prokaryotes.

Explanation:

Bacterial enzyme DNA GYRASE introduce negative supercoiling in closed circular dsDNA. DNA gyrase is a topoisomerase, which takes part in prokaryotic transcription and is not present in eukaryotes except plasmodium. Negative supercoiling allows separation of DNA strand with less torsional stress during replication and transcription.

Answer:

The correct answer is option c. "frameshift mutations".

Explanation:

The reading frame of a gene is based on base-pair triplets, starting from the start codon until the ribosome encounters with the end codon. Base-pair additions and deletions are collectively referred to as frameshift mutations because they alter the reading frame of the gene. Base-pair additions and deletions break down the original sequence of the gene triplets, which alters the open reading frame and usually results in the production of non active proteins.

Which dna mutations is most likely to damage the protein it specifies?
Radda [10]
<h2>DNA Mutations</h2>

Explanation:

<em>    (A) A base-pair deletion</em>

  • <em>Insertion or deletion brings about a frame shift that changes the perusing of consequent codons</em> and, hence, adjusts the whole amino acid arrangement that follows the transformation, additions and cancellations are normally more harmful than a substitution in which just <em>a solitary amino corrosive is modified </em>
  • DNA changes brought about by mutagens may hurt cells and cause certain illnesses,<em> for example, malignancy</em>
  • <em>Instances of mutagens incorporate radioactive substances, x-beams, bright radiation, and certain synthetic compounds</em>

Why is radiometric dating of Carbon not a useful means to determine the age of the earth? What should we use instead of Carbon?
noname [10]

Answer:

Geologists do not use carbon-based radiometric dating to determine the age of rocks. Carbon dating only works for objects that are younger than about 50,000 years, and most rocks of interest are older than that
