Web1 sep. 2024 · But how much of this DNA therefore qualifies as true “junk” in the sense that it serves no useful purpose for a cell? This is hotly debated. In 2012, the Encyclopedia of DNA Elements (Encode) research project announced its findings that about 80% of the human genome seemed to be transcribed or otherwise biochemically active and might … Web18 dec. 2024 · DNA consists of two strands, arranged in a double helix. These strands are made up of subunits called nucleotides. Each nucleotide contains a phosphate, a 5-carbon sugar molecule and a nitrogenous base. RNA only has one strand, but like DNA, is made up of nucleotides. RNA strands are shorter than DNA strands.

Web22 mrt. 2024 · A segment of DNA that codes for the cell’s synthesis of a specific protein is called a gene. DNA replicates by separating into two single strands, each of which serves as a template for a new strand. The new strands are copied by the same principle of hydrogen-bond pairing between bases that exists in the double helix.
