Cellular brassinolide (BL) levels regulate the development of Brassica napus microspore-derived embryos (MDEs). Synthesis and degradation of nucleotides were measured on developing MDEs treated with ...

Nucleotides are essential to all life on Earth as they form the building blocks of DNA or RNA, and understanding how they were first made is a long-standing challenge that must be resolved to ...

This is a preview. Log in through your library . Abstract Nucleotide metabolism was studied in apical 5.0 mm root tips of corn plants (Zea mays L., cv. Pioneer 3906) hydroponically cultured for 7 d ...

A single process for how a group of molecules called nucleotides were made on the early Earth, before life began, has been suggested by a team of researchers. A single process for how a group of ...

Nucleotides are the building blocks of the two nucleic acids, ribonucleic acid (RNA) and deoxyribonucleic acid (DNA). As such, they are also the building blocks of you and every other lifeform on ...

This image illustrates the chemical structure of a purine molecule, highlighting the numbering of the carbon and nitrogen atoms. The purine structure consists of a pyrimidine ring (positions 1 to 6) ...

How life on Earth first started is a mystery mankind has grappled with for thousands of years. Scientists generally agree that all life must have evolved from single-celled organisms that first ...
