What is the overall structure of a DNA molecule? DNA molecules: DNA is a molecule that dictates the distinct features of an organism because it contains the genetic information about the organism. It is unique for different organisms. The DNA molecule, along with the RNA molecule, belongs to ...
DNA is a double-stranded molecule that contains genes, non-coding regions and gene regulatory regions. Genes are hereditary units that encode proteins and define the characteristics of organisms. In other words, genes make you different from other living organisms and other people; genes and DNA m...
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 fact, nearly every cell in a multicellular organism possesses the full set of DNA required...
A molecule's molecular weight is the sum of all its constituent atoms' atomic weights. Avogadro's number (6.02214076 × 1023) is the number of molecules that constitutes the atomic weight of a molecule in grams (g). For example, water is two hydrogen atoms with a weight of 1 g each an...

DNA is made up of molecules called nucleotides. Each nucleotide contains three components: a phosphate group, which is one phosphorus atom bonded to four oxygen atoms; a sugar molecule; and anitrogenbase. The four types of nitrogen bases are adenine (A), thymine (T), guanine (G) and cytos...
DNA is a complex molecule that occurs in all living cells. DNA or Deoxyribonucleic acid is a nucleic acid and one of the major biomacromolecules found... See full answer below. in living systems. Nucleotides are the structural units of DNA. DNA is a polymer of nucleotides and hence known ...
What is a molecule? Despite being a standard scientific concept, it’s virtually impossible to agree a satisfactory definition, says Philip Ball In science, as in life, words often acquire meaning through usage rather than through definition. We use ‘species’ and ‘force’ without being ...
this, a DNA molecule is cut into smaller pieces and then used as a template for a particular strand of RNA that has been copied from the DNA’s matching complementary strand. This RNA is then able to match up with each piece of DNA and can be read off slowly, one letter at a time...
Nucleic acids are the molecules that contain and help express a cell's genetic code. There are two major classes of nucleic acids: deoxyribonucleic acid (DNA) and ribonucleic acid (RNA). DNA is the molecule that contains all of the information required to build and maintain the cell; RNA ha...
