The basic difference between active genes and inactive genes is that active genes are expressed whereas inactive genes are not expressed. This is due to the DNA methylation of the sequences. For DNA replication or copying it must be accessible to the enzymes and the enzymes can access euchromatin and cannot access heterochromatin. The euchromatin is loosely packed form of DNA while heterochromatin is tightly packed form of the DNA. Therefore, the heterochromatin contains the active form of inactive form of genes or the genes are said to be silenced. The DNA bound around the histone proteins are heterochromatins are inaccessible to the enzymes as the histone proteins are in methylated form. The methylation of the histone proteins keeps the genes inactive.

Where are fats, carbohydrates, and proteins broken down into particles small enough to be absorbed into the body?
siniylev [52]

Answer:

Duodenum (option 3)

Explanation:

Digestion of carbohydrates, proteins, and fats continues in the small intestine. Starch and glycogen are broken down into maltose by small intestine enzymes. Proteases are enzymes secreted by the pancreas that continue the breakdown of protein into small peptide fragments and amino acids.

The duodenum is the first section of the small intestine and is the shortest part of the small intestine. It is where most chemical digestion using enzymes takes place

How does the brain develop during adolescence?
