aivan3 [116]

Answer:

DNA ligase

Explanation:

DNA replication is an enzyme mediated, 3-step process during which the DNA molecule produces a copy of itself. The 3 steps involved are as follows;

  • initiation
  • elongation
  • termination

<em>Initiation </em>involves the unwinding of the double helix structure of the DNA using DNA helicase enzyme

<em>Elongation</em> involves binding of RNA primer to the DNA strands and addition of bases to the primer<em> </em>to elongate the new chains. Bases are added to the leading strand continuously while the lagging strand is replicated in short segments (okazaki segments).

<em>Termination</em> involves the unbinding of RNA primer and substitution of its bases by DNA bases. The Okazaki fragments are then joined together using the DNA ligase enzyme.

<em>The short, numerous segments of DNA observed in the mixture is the Okazaki fragments of the lagging strand. This is due to the absence of the enzyme involved in the joining of these fragments.</em>

Hence, the answer is DNA ligase.

dolphin - smart but does not have thumbs to make tools and lives in the ocean meaning they have a disadvantage.

raven - intelligent, works with other ravens and sometimes even wolves, and has shown to make tools.
