we have DNA to make proteins.
amino acids make up proteins and proteins make up DNA which has all the information your body needs
Proteins
Plants need nitrogen to build proteins and nucleic acids.
DNA & RNA are used in making proteins during transcription and translation reactions .
DNA is packaged very tight by proteins. Proteins found around the DNA supports both the structure and functions. The proteins and the DNA make up the chromosomes. Proteins and DNA in animal cells are chromatin! DNA contains information because of the DNA's structure!
proteins
RNA doesn't need proteins nor does it need DNA. RNA probably came first. And it is known that RNA can form peptide bonds which can make proteins. DNA would have come later. They don't need each other, from an evolutionary standpoint. Modern DNA and RNA and proteins are interlocked, but earlier forms clearly weren't.
DNA contains the instructions to make proteins.
Ribosomes make proteins using directions from the head office (DNA).
Proteins make RNA, which then creates DNA.
