DNA

THE REAL NAME IS DEOXYRIBONUCLEIC ACID!!!!!!!!!!!!!!!!!!!!!!

DNA - What is DNA? - Basics of DNA

What DNA do...............

DNA contains the instructions needed for an organism to develop, survive and reproduce. To carry out these functions, DNA sequences must be converted into messages that can be used to produce proteins, which are the complex molecules that do most of the work in our bodies.

Each DNA sequence that contains instructions to make a protein is known as a gene. The size of a gene may vary greatly, ranging from about 1,000 bases to 1 million bases in humans. Genes only make up about 1 percent of the DNA sequence. DNA sequences outside this 1 percent are involved in regulating when, how and how much of a protein is made.

heredity

the passing of traits to offspring from its parents. This is the process by which an offspring cell or organism acquires or becomes predisposed to the characteristics of its parent cell or organism. Through heredity, variations exhibited by individuals can accumulate and cause some species to evolve. The study of heredity in biology is called genetics, which includes the field of epigenetics.

replication

in computing involves sharing information so as to ensure consistency between redundant resources, such as software or hardware components, to improve reliability, fault-tolerance, or accessibility.

what does rna do

To better understand RNA, first realize that it is essential for the information in DNA to remain stable. You can think of the DNA as the "master copy" of a computer program. When you get a new program, you first copy it from the purchased disk onto the hard drive and use that copy of the program for your daily use. You store the original copy of the program away and only use it if the working copy of the program crashes. If DNA information were to be used regularly in the cell, it could accumulate errors, which would be passed on from one generation to the next. Before too long, the DNA would have so many errors that it would lose important functions and wouldn't be able to support the organism. Just as a clever computer user avoids being stuck with a corrupt program by making and storing a master copy, cells use copies of their genomic information for the working processes in the cell. These copies are made of ribonucleic acid, RNA.
