What is deoxyribonucleic acid DNA?
Deoxyribonucleic acid (DNA) is a molecule that encodes an organism’s genetic blueprint. DNA is a linear molecule composed of four types of smaller chemical molecules called nucleotide bases: adenine (A), cytosine (C), guanine (G), and thymine (T). The order of these bases is called the DNA sequence.
What is deoxyribonucleic acid used for?
What does 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.
What are examples of deoxyribonucleic acid?
Extranuclear DNA. DNA outside the nucleus is referred to as extranuclear DNA. Examples of extranuclear DNAs are mitochondrial DNA (mtDNA) and chloroplast DNA (cpDNA). The presence of nucleic acids in these organelles enables them to become semi-autonomous, self-reproducing organelles.
Why is DNA called an acid?
Explanation: More specifically, this acidity comes from the phosphate groups used in forming DNA and RNA molecules. These phosphate groups are quite similar to phosphoric acid. That easily-lost proton is what causes nucleic acids to be so acidic.
What is called DNA?
Deoxyribonucleic acid, more commonly known as DNA, is a complex molecule that contains all of the information necessary to build and maintain an organism. All living things have DNA within their cells. In other words, whenever organisms reproduce, a portion of their DNA is passed along to their offspring.
What are the four different types of DNA?
Because there are four naturally occurring nitrogenous bases, there are four different types of DNA nucleotides: adenine (A), thymine (T), guanine (G), and cytosine (C).
Where is the location of RNA?
cytoplasm
RNA is found mainly in the cytoplasm. However, it is synthesized in the nucleus where the DNA undergoes transcription to produce messenger RNA.
Who found DNA to be acidic?
> These nucleic acids were first isolated in 1868 by a swiss physician Friedrich Miescher and he called it nuclein.
What are the 4 nucleic acids?
Each nucleic acid contains four of five possible nitrogen-containing base s: adenine (A), guanine (G), cytosine (C), thymine (T), and uracil (U). A and G are categorized as purines, and C, T, and U are collectively called pyrimidines. All nucleic acids contain the bases A, C, and G; T, however, is found only in DNA,…
What are the 4 bases in DNA?
The four bases of DNA are: adenine (A), thymine (T), guanine (G), and cytosine (C).
What is the biological function of deoxyribose?
Deoxyribose in DNA. As mentioned above, deoxyribose is a component of the DNA chain which gives it great biological importance. The DNA molecule (deoxyribonucleic acid), is the main repository of genetic information in life.
What does deoxyribonucleic acid mean in medical dictionary?
deoxyribonucleic acid. 1. (DNA) A molecule found in a cell nucleus that carries genetic information. 2. (DNA) A nucleic acid in the cell’s chromosomes, which contains the cell’s coded gene tic instructions. See gene.
