What You Didn't Know About Your DNA
In high school, you might've learned the basics of DNA. Does it really define who you are, or is there more to it?
DNA can't explain all inherited biological traits, research shows (Science Daily)
"Characteristics passed between generations are not decided solely by DNA, but can be brought about by other material in cells, new research shows. Scientists studied proteins found in cells, known as histones, which are not part of the genetic code, but act as spools around which DNA is wound. Histones are known to control whether or not genes are switched on."
Rosalind Franklin: Biography & Discovery of DNA Structure? (Live Science)
"Many people recall that the structure of the DNA molecule has the shape of a double helix."
What Are Proteins And What Do They Do? (Genetics Home Reference)
"Proteins are large, complex molecules that play many critical roles in the body. They do most of the work in cells and are required for the structure, function, and regulation of the body's tissues and organs."
Histone / Histones (Nature)
"Histones are a family of basic proteins that associate with DNA in the nucleus and help condense it into chromatin. Nuclear DNA does not appear in free linear strands; it is highly condensed and wrapped around histones in order to fit inside of the nucleus and take part in the formation of chromosomes."
