Dictionary » D » DNA DNADefinition noun A double-stranded nucleic acid that contains the genetic information for cell growth, division, and function.
Structure: DNA is composed of two strands that twist together to form a helix. Each strand consists of alternating phosphate (PO4) and pentose sugar (2-deoxyribose), and attached on the sugar is a nitrogenous base, which can be adenine, thymine, guanine, or cytosine. In DNA, these bases pair; adenine pairs with thymine and guanine with cytosine. Hence, DNA is a ladder-like helical structure. Location: DNA is found in the cytoplasm of prokaryotic cells, and chiefly in the nucleus of eukaryotic cells. A small fraction of total DNA is present in mitochondria and chloroplasts. Function: DNA is a long polymer of nucleotides to code for the sequence of amino acid during protein synthesis. DNA is said to carry the genetic ‘blueprint’ since it contains the instructions or information (called genes) needed to construct cellular components like proteins and RNA molecules.

Results from our forumProducing unknown proteinDrfuture, your question is too vague. Protein form which organism? Do you have DNA sequence or just protein? General answer to your question: 1. Backtranslate protein sequence to DNA sequence. 2. Codon optimize to the expression system (you have a choice of bacterial ...

How Genes/expression Determine Organism ShapeCan anyone give a relatively general account on how DNA and gene expression determine an organism's physical shape, i.e., size, skeletal structure, body shape, etc. I would presume the explanations for size and shape are distinct or merely dependent ...

A Potential Plan To Save Endangered Species... bears to Antarctica, tigers to Africa, chimpanzees to South America and so on. I also came up with a plan B. We need to urgently conserve the DNA of every single species on Earth and keep it stored until the technology advances enough for bringing those species back in case they were extinct ...

the cultivation of genetics and DNA of Kazakhs people... For sure similar restriction is meaningful, but 7 generations seems a little too much. One'd share on average only 1/2^7 of their DNA, that's less than 1%. I think the general 2-3 generations should be sufficient. It's rather more crucial when the relativeness is high as could ...
