Genes, Traits, and Proteins

what is the relationship between dna genes and protein

Each gene tells the cell how to put together the building blocks for one specific protein. However, the gene (DNA) sits inside a different compartment of the cell. Each gene codes for a specific protein by specifying the order in which amino acids must be The diagram shows the relationship between the cell, its nucleus . Ever wondered the relationship between genes and proteins? organism that normally resides in long strands of DNA called chromosomes.

What is the relationship between DNA , genes, and proteins?

These biological molecules, the building blocks of DNA, are often abbreviated with the first letter of their names: This in turn determines the types and order of amino acids included in proteins. Specific three-letter groups of RNA nucleotides code for specific amino acids.

The combination TTT, for example, codes for the amino acid phenylalanine. Regulatory regions of the gene also contribute to protein synthesis by determining when the gene will be switched on or off.

Sciencing Video Vault Proteins In active genes, genetic information determines which proteins are synthesized and when synthesis is turned on or off. These proteins fold into complicated three-dimensional structures, somewhat like molecular origami.

Because each amino acid has specific chemical characteristics, the sequence of amino acids determine the structure and shape of a protein. For example, some amino acids attract water, and others are repelled by it.

Some amino acids can form weak bonds to each other, but others cannot. Proteins are chains of chemical building blocks called amino acids. A protein may contain a few amino acids or it could have several thousands. The size of a protein is an important physical characteristic that provides useful information including changes in conformation, aggregation state and denaturation. Protein scientists often use particle size analysers in their studies to discuss protein size or molecular weight.

Archibald Garrod Archibald Garrod was one of the first scientists to propose that genes controlled the function of proteins.

Inhe published his observations regarding patients whose urine turned black. This condition known as alkaptonuria happens when there is a buildup of the chemical homogentisate, which causes the darkening of urine. In most situations, excess amounts of amino acid phenylalanine are metabolised by the body.

This led Garrod to surmise that the enzyme responsible for its breakdown must be defective in these patients. In addition, since the black urine phenotype was passed from generation to generation in a regular pattern, Garrod reasoned that a gene had to be responsible for the production of the defective enzyme.

He attributed a defective enzyme to a defective gene, suggesting a direct link between genes and proteins. The Relationship Between Genes and Proteins Most genes contain the information require to make proteins.
