Asked in Molecular Biology
What are the three main principles in molecular biology?
genetic information begins with DNA and is transcribed to RNA and then translated into proteins: DNA→RNA→proteins. ...
Asked in Genetics
What was the basis of the belief of biologists for over two decades that proteins instead of DNA were the genetic material?
Proteins are made of 20 amino acids while DNA is made of four nucleotides; Proteins have a greater variety of three dimensional forms than does DNA. ...
Asked in Biology, Microbiology, Genetics
How are the instructions for assembling amino acids into proteins encoded into DNA?
There are 20 amino acids, but there are only four nucleotide bases in DNA. ...

What proteins might be associated with DNA in the cell?
Histones are proteins which are associated with DNA and from nucleosomes, which pack the DNA. Transcription factors, proteins involved in DNA synthesis, replication... ...
Does DNA contain proteins?
DNA are not chemically having protein. But DNA are coiled to chromatin structures by proteins called histones. DNA can interact with proteins for various reason including DNA replication. DNA are not chemically bonded with proteins. But they do interact with protins for various process including DNA replication. In nucleus, DNA coiled to form chromatin structures by histone proteins. ...
Asked in Biology, Plastics and Polymers
What are four main classes of polymers in living things?
They are Nucleic acid - from cells, Proteins - translated from genes, lipids - from proteins and carbohydrates - from proteins. ...
Asked in Genetics
Explain how proteins help support the structure and function of DNA?
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! ...
Asked in Genetics, Biotechnology
What role does DNA play in an organism?
DNA is composed of four deoxyribonucleic acids. The sequence of these determines the sequence of amino acids in proteins. Proteins are essential in maintaining and multiplying cells. Additionally DNA is structured in such a way that it can be copied exactly when the cell prepares to divide. ...
