Our guide picked us up and entertained us the whole way, taking us to the best spots â we even had a close encounter with a bear on the side of the road! This wildlife photo tour will explore the wildlife, geology, and natural history of Grand Teton National Park.
Chromosomes contain smaller units of genetic material called DNA. DNA is a sequence of letters that spell out the genetic code. The DNA is organized into words and sentences called genes. Humans have approximately 20,000 genes and each one influences a part of development. These genes usually come in pairs.
These proteins are grouped together called an operon. In terms of structure, RNA, like DNA, is composed of an extensive chain of elements also termed as nucleotides. A nucleotide has three complex groups, namely: the nucleobase or nitrogenous base, the phosphate group, and a ribose sugar.
