What defines gene expression?

Gene expression is the process by which the information encoded in a gene is used to direct the assembly of a protein molecule.

Which best describes gene expression?

Gene expression is the process by which the instructions in our DNA are converted into a functional product, such as a protein. ... It acts as both an on/off switch to control when proteins are made and also a volume control that increases or decreases the amount of proteins made.

What factors determine gene expression?

Various factors, including genetic makeup, exposure to harmful substances, other environmental influences, and age, can affect expressivity. Both penetrance and expressivity can vary: People with the gene may or may not have the trait and, in people with the trait, how the trait is expressed can vary.

What does gene expression mean quizlet?

gene expression. the activation or "turning on" of a gene that results in transcription and the production of mRNA. genome. the complete genetic material contained in an individual.

What is gene expression example?

Some simple examples of where gene expression is important are: Control of insulin expression so it gives a signal for blood glucose regulation. X chromosome inactivation in female mammals to prevent an "overdose" of the genes it contains. Cyclin expression levels control progression through the eukaryotic cell cycle.

What is gene expression Slideshare?

INTRODUCTION GENE EXPRESSION It is the process by which a gene's DNA sequence is converted into the structures and functions of a cell. Non-protein coding genes are not translated into protein.

Is gene expression transcription or translation?

Together, transcription and translation are known as gene expression. During the process of transcription, the information stored in a gene's DNA is passed to a similar molecule called RNA (ribonucleic acid) in the cell nucleus.

Which statement best describes the role of gene expression in cells quizlet?

Terms in this set (26) Which statement best describes the role of gene expression in cells? To become specialized, cells need to control the production of proteins coded for in their DNA.

Which of the following best describes the process of gene expression?

Which of the following best describes what happens during gene expression? A cell reads the instructions in DNA and builds a protein based on those instructions. Transcription takes place in the nucleus, and translation takes place in the cytoplasm. ... DNA-binding proteins determine whether a gene is expressed.

What alters gene expression?

Several genetic or epigenetic events can alter gene expression and we assess their importance in multistage carcinogenesis. Mutation and chromosome rearrangement can produce changes in DNA sequence which have been identified in some cancer cells.

How do cells know which genes to express?

How do these cues help a cell "decide" what genes to express? Cells don't make decisions in the sense that you or I would. Instead, they have molecular pathways that convert information – such as the binding of a chemical signal to its receptor – into a change in gene expression.

What is gene expression and what are the two stages?

Regulation of the two main steps of protein production — transcription and translation — is critical to this adaptability. Cells can control which genes get transcribed and which transcripts get translated; further, they can biochemically process transcripts and proteins in order to affect their activity.

When a gene is expressed it is quizlet?

Terms in this set (10) What does it mean for a gene to be expressed? Gene expression occurs when the gene is turned on, transcription occurs and the protein is made via translation. -Special proteins called transcription factors bind to the promoter region which helps DNA to bend and initiate transcription.

How does gene expression work quizlet?

Gene Expression: The process in which an RNA copy of each active gene is made, and the RNA copy directs the sequential assembly of a chain of amino acids at a ribosome. ... 2) Then, ribosomal RNA (rRNA) serves to initiate the translation of the mRNA copy into an amino acid sequence.

Where Does gene expression occur?

Eukaryotic gene expression is regulated during transcription and RNA processing, which take place in the nucleus, and during protein translation, which takes place in the cytoplasm. Further regulation may occur through post-translational modifications of proteins.

How does a gene get translated?

The entire process is called gene expression. In translation, messenger RNA (mRNA) is decoded in a ribosome, outside the nucleus, to produce a specific amino acid chain, or polypeptide. ... The ribosome then moves to the next mRNA codon to continue the process (translocation), creating an amino acid chain.

Is gene expression the same as protein synthesis?

They have different proteins because different genes are expressed in different cell types (which is known as gene expression). ... Once a gene is expressed, the protein product of that gene is usually made. For this reason, gene expression and protein synthesis are often considered the same process.
