How does DNA hold information?

Answer 1

You can think of DNA as a code or a very short alphabet with only four letters: A, C, G and T. The letters are arranged in groups of three called codons, and each codon codes for a single amino acid. Amino acids are what make up your proteins, and proteins are what cause you to look and function as a human being. You can change the end product by changing the order of the letters, just as you could change a book by changing the order of the letters.

You can copy DNA, just like you could copy a computer program or book, and you could share it with your children (reproduction).

Answer 2

DNA represents a code and first think about what a code is. A code uses symbols to transmit information and information is nonmaterial. Look at this bit of information. STOP stop Both give you informatuion but is it the size of the letters? No, it is the arrangement of the ink. Secondly it makes no differenc e how big my letters are the information is the same so size is immaterial also. What is the code here? The letters of the alphabet.
What is the DNA code? There are four symbols (chemical compounds) in the code. We call them A,T,G and C. Now you can arrange these four symbols in different sequences. DNA is made up of strands of these four symbols in thousands and the sequence is the code. Example:
AGCGTTAAGC is one sequence
GCTTAGCTTG is another
A code must be read and DNA code is read when a particular protein is made in the cell. One sequence brings about hemoglobin for example and another insulin. If only one symbol is changed the sequence is different and the code is read differently. In cystic fibrosis there is an error in the sequence and the disease appears.
This remarkable code is the secret of life.

Answer 3

short answer- protiens and other chemicals cause specific reactions in the body which have specific effects.

long answer:
Chromosomes

Cells, whether through meiosis or mitosis, share genetic information through chromosomes. Chromosomes are the package for DNA and genes. A living organism has roughly 5 feet or 1.5 meters of compacted DNA within it's nucleus. To contain the DNA within the nucleus of a cell, the genetic information is wound up into strands like coiled rope. These strands take the shape of X's. Each place on a chromosome holds genetic information which pertains to the expression of a trait. The genetic information a chromosome holds, or one piece of genetic information a chromosome can hold, is known as a gene. An allele is a point or place on a chromosome. The locus is a place on a specific chromosome where a gene is found.

Answer 4

dna contains agens in which information is store for an eg if cell want to syntesis the proteins with the help of this information present in dna proteins r syntesied in information is stored in form of codon this information is specific

Answer 5

They have computers to hold all this stuff, and to track drug criminals, and other ne'er do wells. Do not hide from the DNA - they will find you and burn your compound down, like they did in Waco.
