amolecule that contains all the information a cell needs to make protein
A gene is a segment of a DNA molecule that contains the instructions needed to make a unique protein. All of our cells contain the same DNA molecules, but each cell uses a different combination of genes to build the particular proteins it needs to perform its specialised functions. Protein synthesis has 2 main stages. Most genes contain the information needed to make functional molecules called proteins. (A few genes produce other molecules that help the cell assemble proteins.) The journey from gene to protein is complex and tightly controlled within each cell. DNA is the molecule that contains the hereditary information of a cell. 2 people found this useful. Edit. Share to: 1  The Many Functions of Proteins: A Biological Overview Proteins are macromolecules composed of amino acids that serve a wealth of biological functions in an organism. DNA contains all the information a cell needs in order to make certain proteins Where are the protein-synthesizing instructions stored on a DNA molecule? This molecule is transcribed from the DNA molecule and carries a copy of the information needed to make a protein. In the 2 nd stage, the mRNA molecule leaves the nucleus for the cytoplasm where the cell’s ribosomes read the information and start to assemble a protein in a process called translation. During the process of transcription, the information stored in a gene’s DNA is transferred to a similar molecule called RNA (ribonucleic acid) in the cell nucleus. Both RNA and DNA are made up of a chain of nucleotide bases, but they have slightly different chemical properties. (A few genes produce other molecules that help the cell assemble proteins.) The journey from gene to protein is complex and tightly controlled within each cell. It consists of two major steps: transcription and translation. Together, transcription and translation are known as gene expression. We will see you on the screen as a guest star in the upcoming season of BET's Being Mary Jane, BET's first scripted hour-long drama. the order of bases. DNA is essentially a storage molecule. It contains all of the instructions a cell needs to sustain itself. These instructions are found within genes, which are sections of DNA made up of specific sequences of nucleotides. Protein synthesis has 2 main stages. The 1 st stage is known as transcription, where a messenger molecule (mRNA) is formed. This molecule is transcribed from the DNA molecule and carries a copy of the information needed to make a protein.
