Scientists have observed that mice with LOW birthweight are MORE likely to become obese. To study this, they compared methylation in the promoter region of the leptin gene
in low birthweight (LBW) and normal birthweight (NBW) individuals by treating isolated DNA from both sets of mice with bisulfite and comparing the sequencing results. The
results are shown below. What conclusion can you draw?
Untreated:
ATTCGATTCGCGAA
Treated NBW:
ATTCGATTCGCGAA
Treated LBW:
ATTTGATTCGTGAA
LBW individuals have unmethylated Cs in the promoter region, which ultimately leads to lower expression of the leptin gene.
LBW individuals have methylated Cs in the promoter region, which ultimately leads to higher expression of the leptin gene.
LBW individuals have methylated Cs in the promoter region, which ultimately leads to lower expression of the leptin gene.
LBW individuals have unmethylated Cs in the promoter region, which ultimately leads to higher expression of the leptin gene.
