Answer:
<u>B) 3 amino acids joined by 2 peptide bonds</u>
Explanation:
The general formula of amino acids:
<u>R-CH(NH2)-COOH </u>
It can be seen clearly in the attached image that there are three amino acid molecules.
Now the three molecules of amino acids are joined by 2 peptide bonds.
<u>Peptide bond: </u> a bond formed between first carbon of one amino acid and nitrogen of another amino acid releasing a water molecule( H2O).
The answer is restriction enzymes. These staggered ends are important in recombination of DNA since they allow DNA strands with complementary sticky ends to be easily joined into one piece by DNA ligase. Other restriction enzymes produce blunt ends. These are harder to join by DNA ligase. An example of a restriction ezyme if EcoRI
