DNA is fundamental to the biology of all life on Earth, but how many of us actually know what it is or what it's made of?

DNA and RNA are important components of living organism. ... It has two nucleotide strands consisting of a phosphate group, five carbon sugar (stable deoxyribose 2) and four nitrogen bases.

There's far less agreement, however, on how those RNA bases themselves first form. These bases have a combination of one of two types of flat, ringed structures linked to a small, ring-shaped sugar.

Miller and Urey wouldn't have known how significant of a finding it was, but it definitely showed up in the new work. It didn't go on to form any of the RNA bases, but that was expected, as these ...

How can just four nitrogenous bases--adenine, cytosine, guanine, and uracil--possibly code for all 20 amino acids? Thus, early researchers quickly determined that the smallest combination of As ...

More of the ingredients for life have been found in meteorites. Space rocks that fell to Earth within the last century contain the five bases that store information in DNA and RNA, scientists ...

RNA is also made of a long string of bases: guanine, cytosine and adenine (like DNA), but instead of thymine it has uracil — which is what turned up in the sample from Ryugu.

WEST LAFAYETTE, Ind. – Plant breeders could theoretically increase soybean crop yields if they could control the number of nodules on plant roots since they are responsible for fixing atmospheric ...
