Solution:

Microsatellites are the regions in the genome where we can found repetitive DNA sequences.
Palindromes can be defined as the sequence that reads the same backward as forward when orientation is kept the same.
Guanine is base-paired with Cytosine by three hydrogen bonds, whereas Adenine is base-paired with Thymine by two hydrogen bonds only. The more the number of hydrogen bonds more will be the melting point.
