Sentences with phrase «genetic alphabet»

The phrase "genetic alphabet" refers to the set of chemical letters or building blocks that make up our DNA. It consists of four base molecules called adenine (A), cytosine (C), guanine (G), and thymine (T). These letters combine in specific sequences to store and transmit the genetic information responsible for our traits and characteristics. Full definition

For several years now, scientists have been learning how to attach the four nucleotides of our genetic alphabet to new backbones.
Using similar methods, he hopes to decipher the temporal order of more of the code — determining when each letter was added to the genetic alphabet — and to date key events in the origins of life, such as the emergence of cells.
But it might have arisen independently multiple times, says Powell, because repetitions of the same letter of the genetic alphabet are prone to errors.

Lab rats, for example, contain about 30,000 genes on a genetic alphabet 2.75 billion letters long.
These so - called APOBEC proteins seek out certain combinations of the letters that make up DNA (called bases), and, in DNA of viral origin, chemically convert the base cytosine into the base uracil — a change in the genetic alphabet from C to U that can disrupt a gene.
Over the decades, synthetic biologists trying to expand life's genetic alphabet have come up with a handful of alternative genetic letters.
Natural DNA consists of a ladder frame of ring - shaped deoxyribose molecules (which form the backbone of the double helix) and rungs of bases (which spell out the genetic alphabet).
