SDS-PAGE electrophoresis is used to verify the purity of a protein product. Some of the limitations of this method are:
<span><span>· </span>identification of a band on a protein gel is not always reliable because different polypeptides can have very similar molecular masses,</span>
<span><span>· </span>band on a protein gel may mask the presence of more than one polypeptide,</span> <span><span>· </span><span>presence of non-protein residues can affect the mobility of polypeptide and thus cause an error.</span></span>
Answer:
Skeletal muscles
Explanation:
Skeletal muscles contribute to maintaining temperature homeostasis in the body by generating heat. Muscle contraction requires energy and produces heat as a byproduct of metabolism.
