DNA encodes information through the order, or sequence, of the nucleotides along each strand. Each base—A, C, T, or G—can be considered as a letter in a four-letter alphabet that spells out biological messages in the chemical structure of the DNA.
Deoxyribonucleic acid or DNA is a molecule that contains the instructions an organism needs to develop, live and reproduce. These instructions are found inside every cell, and are passed down from parents to their children. DNA structure. DNA is made up of molecules called nucleotides.
Structure of DNA. How Can DNA Store and Copy Information? DNA Replication. Complementary Base Pairing Allows Each Strand of DNA to Serve as a Template for DNA Replication.
One of the fundamental things to know when studying genetics is the basic structure of DNA and how it is replicated. DNA is the “blueprint” that contains all the instructions for making the proteins that each cell needs, whether it is a single celled bacterium or a multicellular organism like humans. J.
DNA as it is passed down from generation to generation. Next, we discuss the cellular mechanisms—DNA replication and DNA repair—that are responsible for keeping these changes to a minimum. Finally, we consider some of the most intriguing ways in which DNA sequences are altered by cells, with a focus on
