The full scientific name for DNA is deoxyribonucleic acid. Passed from adult organisms to their offspring, it contains the genetic instructions for the design of that organism.Know More
DNA stores genetic information in one of four chemical bases that pair up with each other. The order of the pairs is what makes each person's DNA unique. Found inside the cell nucleus, very small portions of DNA are packaged into individual chromosomes. Human babies receive exactly half of their DNA from their mother and half from the father, creating a new, unique, person.
First observed in the 1800s by Swiss Biochemist Frederich Miescher, it took scientists nearly a century to discover the importance of DNA in life. Visual representations of DNA take the form of a double helix model, which resembles a ladder. Each rung of the ladder is made up a base pair. The bases pair in a very specific pattern, with adenine always pairing with thymine and cytosine always pairing with guanine. The predictability of these pairings has made it easier for scientists to understand how DNA works. During cell division, the base pairs split up, with each base connecting with a different counterpart, which leads to the formation of new cells.Learn more about Molecular Biology & DNA
Complementary base pairing refers to the structural pairing of nucleotide bases in deoxyribonucleic acid, which is commonly known as DNA. DNA is made up of four nucleotide bases, each of which pairs with only one of the other bases.Full Answer >
Both DNA and RNA are macromolecules that consist of long chains of nucleotides. Both contain the specific nucleotide bases adenine, guanine and cytosine, although the fourth base differs between DNA and RNA. Both molecules are found in the cell's nucleus, but RNA may also be found in the cytoplasm.Full Answer >
Without DNA, life would not be able to perpetuate itself. DNA is needed as it is the blueprint of life. Every species of plants and animals contains a genetic substance called DNA that passes on the physical characteristics of an organism from one generation to the next.Full Answer >
DNA, which stands for deoxyribonucleic acid, is the hereditary material passed down from parents to progeny in almost all living organisms, including humans. DNA encodes sets of genes that govern every heritable attribute in living organisms.Full Answer >
