It has lost its active 3D structure and therefore it is not functional anymore.
Shape, therefor function.
Shape, function and hydrogen bonds.
Histones
they determine the sequence of amino acids in a protein i think
The dependence of protein function on a protein's specific shape becomes clear when proteins are altered. Denaturation is the process by which proteins lose their structure and function because of an outside factor, such as a change in temperature or pH.
DNA is the main source of protein synthesis. the process in which DNA makes protein is called transcription. first DNA makes RNA with the help of a blue molecule found in the nucleus. now these RNA gets out of the nucleus and is bounded by another molecule which secrets protein from RNA. there are special transfer molecules for carrying proteins
Well, literally, DNA replication is DNA copying itself, and protein synthesis is producing protein molecules according to the DNA sequences.DNA replication occurs only once in each cell generation during the S phase of the cell cycle, you might know, but the protein synthesis can occur as many times as needed.As you know, the DNA is double-stranded. In the replication, the strands are separated creating replication fork. However, in protein synthesis, the strands are separated and mRNA is transcribed by RNA polymerase.Protein is synthesized by special molecules known as RNA molecules(mRNA, tRNA, and rRNA), which are not needed in DNA replication.Protein synthesis requires amino acids, whereas DNA replication requires Nucleic acids.
protein and DNA
Protein Molecules. "Dna coild around protein molecules called histones."
DNA is double-stranded, unless it has been denatured, then the two strands separate, forming two single-stranded molecules.
Im not sure. Sorry.
Histones
No. RNA and Protein do
DNA (and sometimes RNA).
First of all, a protein consists of chains of amino acids and a single amino acid is coded by one codon of DNA. Mutations are able to insert, delete, replace and shift codons, which can result in amino acids being changed, removed or added, which would affect the protein that the amino acids are building.For example;Here is a strand of DNA in which the three codons in the middle codes for the amino acids.....TGG ATT ATG GAG TTC....-----> Isoleucine, Methionine, Glutamic acidSay that the strand of DNA has it's reading frame mutated (shifted).....GGA TTA TGG AGT TC....-----> Leucine, Tryptophan, SerineNotice how completely different amino acids arose from the mutation. Such a change may effect the protein's characteristics, as well as the phenotype of the organism.
protein and DNA Each chromosome in the nucleus includes one macromolecule of DNA, folded and coiled with protein molecules to reduce its size.
The chromosome. It is very long single thread of DNA. There are many genes, which signal production of the protein molecules.
This enzyme is known as DNA helicase.
DNA molecule is what makes proteins. This is in the body.
