Answer:
The correct answer is "negative".
Explanation:
At pH 2 the net charge of the R groups of all the amino acids that comprise the peptide in question would be positive. This happens because of the high content of protons in a solution of pH 2, a value that is below the isoelectric point of all the amino acids. Since the peptide would have a positive net charge, it would migrate to the negative terminal of the gel because opposite charges attract each other.

Amniocentesis is a freshly established test for identifying fetal duchenne's muscular dystrophy.
<h3>What is tested for during an amniocentesis?</h3>
Amniocentesis is a test that may be recommended to you during pregnancy to determine whether your unborn child has a chromosomal or genetic disorder like Down syndrome, Edwards syndrome, or Patau's syndrome.
<h3>What exactly does an amniocentesis entail?</h3>
A little sample of amniotic fluid is removed during an amniocentesis operation for testing. This is the fluid that a pregnant woman's fetus is enclosed in. The amniotic fluid shields the fetus from harm and is transparent and pale yellow in color. provides infection protection.
<h3>What takes place after a positive amniocentesis test?</h3>
If the test yields a positive result, the fetus may have the genetic disorder. To confirm this, more testing are sometimes required.
