Covalent bonds are formed when two atoms are able to <em>share</em> electrons.

Iroinic bonds are form when two atoms are <em> </em> electrons from each other to complete the bond. This results in a pair of ions.


<u>Covalent bonds:</u>

  • Have a definite shape.
  • Have a low melting point.
  • At room temperature they are in a liquid or gas.
  • They occur between two non-metals.

<u>Ionic bonds:</u>

  • Have no definite shape.
  • Have a high melting point.
  • At room temperature they are solid.
  • They occur between a metal and a nonmetal.

Elenna [48]

Answer:

C) are sequence-specific DNA endonucleases

Explanation:

Restriction enzymes represent a type enzyme capable of recognizing short nucleotide sequences to cut at specific restriction sites in the DNA, these sites are known as target DNA sequences. Some of the most commonly used restriction enzymes are <em>EcoRI</em>, <em>BamHI</em> and <em>HindIII</em>, isolated from <em>Escherichia coli</em>, <em>Bacillus amyloliquefaciens</em> and <em>Haemophilus influenza</em>, respectively. Restriction enzymes are endonucleases because these enzymes only cleave the phosphodiester bond within the DNA chain, conversely to exonucleases, which cleave nucleotides from the end of the polynucleotide DNA strand.
