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:
Yes
Explanation:
Vaccines, are dangerous but also very helpful. Most vaccines we have now help prevent the original disease they are designed with. Such as Polio.
Help this Helps!
Answer:
1/2
Explanation:
Assuming the gene is represented by the allele G (dominant), the alternate form (recessive) of the allele will be g.
A heterozygous pea plant will have the genotype Gg. During gamete formation, Gg will split into G and g gametes.
<em>The probaility that a gamete will contain the recessive allele for flower color is 1/2.</em>
Answer:
Heart valves or the closure of the mitral and tricuspid atrioventricular (AV) valves at the beginning of ventricular systole and the closure of the aortic valve and pulmonary valve at the end of ventricular systole.
Explanation:
The heart tone “lub,” or S1, is caused by the closure of the mitral and tricuspid atrioventricular (AV) valves at the beginning of ventricular systole.
The heart tone “dub,” or S2 ( a combination of A2 and P2), is caused by the closure of the aortic valve and pulmonary valve at the end of ventricular systole.
