The human body wants blood glucose (blood sugar) maintained in a very narrow range. Insulin and glucagon are the hormones which make this happen. Both insulin and glucagon are secreted from the pancreas, and thus are referred to as pancreatic endocrine hormones. The picture on the left shows the intimate relationship both insulin and glucagon have to each other. Note that the pancreas serves as the central player in this scheme. It is the production of insulin and glucagon by the pancreas which ultimately determines if a patient has diabetes, hypoglycemia, or some other sugar problem.(i hope this can help you) :)

Ribonucleic acid (rna) and additional deoxyribonucleic acid (dna) surrounds genes. in a process called methylation, they enhance, silence, or alter genetic instructions.
<h3>What is DNA methylation?</h3>
- Adding methyl groups to the DNA molecule is a biological process known as DNA methylation. Methylation has the ability to change a DNA region's activity without changing the sequence.
- When DNA methylation takes place at a gene promoter, it frequently decreases gene transcription.
- DNA methylation plays an important role in a number of critical processes in mammals, including aging, cancer, X-chromosome inactivation, genomic imprinting, and transposable element repression.
- The majority of eukaryotic genomes contain DNA methylation, a dynamic epigenetic alteration. It is well recognized to cause a high rate of CpG to TpG mutations.
- However, nothing is known about the connection between the rate of germline mutation and the dynamics of methylation during germline development.
