In short, DNA is a complex molecule that consists of many components ... this highly compacted DNA is then arranged into structures called chromosomes. Chromosomes take different shapes in ...

A chromosome is a single, long molecule of DNA. These highly organized structures store genetic information in living organisms. Small sections of the chromosome, called genes, code for the RNA ...

Chromosomes are thin strands of DNA (deoxyribonucleic acid). A gene is a short length of DNA found on a chromosome that codes for a particular characteristic or protein. Alleles are different ...

DNA can be cut up and separated, which can form a 'barcode' that is different from one person to the next. Each human body cell contains 46 chromosomes. These can be arranged into 23 pairs.

This coiling causes the chromosome to resemble a spring. Chromatin refers to proteins that help organize the long DNA molecule. The protein shown here supports and organizes small loops of DNA.

When bacterial DNA is labeled with radioactive atoms, it takes its own picture. Autoradiographs reveal that the bacterial chromosome is a single very long DNA molecule and show how it is duplicated ...

Whether it is a microbe, a rose, or a dolphin, any form of life gets its building and operating instructions from the molecule of life, DNA. DNA comprises the genes and chromosomes that govern the ...

DNA stands for deoxyribonucleic acid. Nucleic acids are named for where they're found—inside the nuclei of cells—and for the ...
