DNA, short for deoxyribonucleic acid, is the molecule that contains the genetic code of organisms. This includes animals, plants, protists, archaea and bacteria. DNA is in each cell in the organism and tells cells what proteins to make. Mostly, these proteins are enzymes.
DNA is a record of instructions telling the cell what its job is going to be. A good analogy for DNA as a whole is a set of blueprints for the cell, or computer code telling a PC what to do. It is written in a special alphabet that is only four letters long! Unlike a book or computer screen, DNA isn't flat and boring - it is a beautiful curved ...
What is DNA? How does it make us who we are, and what do we know about it? Can you make your own tasty DNA model? What is DNA? How does it make us who we are, and what do we know about it? ... We are science made simple, a social organisation which promotes science, maths and engineering in schools and to the public.
Well DNA can't really be in a simple explanation. It is a deoxyribonucleic acid that strands our genetic material together into a double-stranded genome.
The structure of DNA and RNA. DNA is a double helix, while RNA is a single helix. Both have sets of nucleotides that contain genetic information.
DNA A. adenine T. thymine C. cytosine G. guanine DNA (dē′ĕn-ā′) n. A nucleic acid that carries the genetic information in cells and some viruses, consisting of two long chains of nucleotides twisted into a double helix and joined by hydrogen bonds between the complementary bases adenine and thymine or cytosine and guanine. DNA sequences are ...
DNA replication is the process of copying a double-stranded DNA molecule. Both strands serve as templates for the reproduction of the opposite strand. The process is sometimes called "semi-conservative replication" because the daughter DNA from the original parent strand contains half of the original and half of the newly synthesized DNA.
Within each string of DNA are sets of instructions called genes. A gene tells a cell how to make a specific protein. Proteins are used by the cell to perform certain functions, to grow, and to survive. Shape of the DNA Molecule Although DNA looks like very thin long strings under a microscope, it turns out that DNA has a specific shape.
DNA replication is the process by which DNA makes a copy of itself during cell division. Lagging strand: Numerous RNA primers are made by the primase enzyme and bind at various points along the lagging strand. Chunks of DNA, called Okazaki fragments, are then added to the lagging strand also in the ...
DNA is the material that carries all the information about how a living thing will look and function. For instance, DNA in humans determines such things as what color the eyes are and how the lungs work. Each piece of information is carried on a different section of the DNA. These sections are called genes. DNA is short for deoxyribonucleic acid.
