Which of the following best describes what happens during 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.
Which of the following correctly describes gene expression?
Which of the following statements correctly defines the process of gene expression? Gene expression is the process by which DNA directs the synthesis of proteins.
What is the role of a gene in the cell quizlet?
Genes encode enzymes that synthesize these products. Since there are no genes coding for carbohydrates, nucleic acids, or lipids, how do cells produce them? Any change in the structure of a chromosome or a DNA molecule, often resulting in a change of structure or function in the protein produced, is known as a(n) .
How gene expression describe in detail?
Gene expression is the process the cell uses to produce the molecule it needs by reading the genetic code written in the DNA. To do this, the cell interprets the genetic code, and for each group of three letters it adds one of the 20 different amino acids that are the basic units needed to build proteins.
What processes are involved in gene expression?
It consists of two major steps: transcription and 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 of the following best describes the order of events that lead to genetic expression?
Answer and Explanation: The correct answer to this question is: c. DNA → RNA → proteins. DNA is first transcribed into RNA in the nucleus of the…
What is gene expression 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.
Why is gene expression important?
Gene expression is important because a specific protein can be produced only when its gene is turned on. But it takes more than one step to get from gene to protein, and the process of building proteins is a key step in the gene expression pathway that can be altered in cancer.
What is the role of a gene in the cell?
A gene is a short section of DNA. Your genes contain instructions that tell your cells to make molecules called proteins. Proteins perform various functions in your body to keep you healthy. Each gene carries instructions that determine your features, such as eye colour, hair colour and height.
How do genes allow cells to carry out important life functions?
How do genes allow cells to carry out important life functions? Genes can code for proteins, which help determine the specialized roles of cells. Protein A is a structural protein that forms long strands in the cell, while Protein B is a globular protein that functions as an enzyme.
What is the importance of gene expression?
Gene expression is important because a specific protein can be produced only when its gene is turned on. But it takes more than one step to get from gene to protein, and the process of building proteins is a key step in the gene expression pathway that can be altered in cancer.
Which statement best describes the flow of genetic information in a cell?
Answer and Explanation: The correct answer to this question is: c. DNA → RNA → proteins.
What is the purpose of gene expression?
Gene expression is a tightly regulated process that allows a cell to respond to its changing environment. 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 is gene expression in biology quizlet?
gene expression. the overall process by which genetic information flows from genes to proteins/genotype to phenotype.
What is an example of gene expression?
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.
Why are genes expressed?
Gene expression is a tightly regulated process that allows a cell to respond to its changing environment. 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.
Which of the following phrases best describes the role of mRNA in gene expression?
Which of the following phrases best describes the role of mRNA in gene expression? Information from DNA is transcribed into mRNA which is then transported to ribosomes. Which of the following is not a role of the ribosome or its subunits? In the translation process, tRNA molecules are also called "adapter" molecules.
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.
What is the best meaning for the term gene expression quizlet?
Gene expression is. the activation of a gene leading to the transcription, translation and synthesis of a specific protein.
How is genetic information expressed in cells?
It consists of two major steps: transcription and 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.
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 does gene expression produce?
Gene expression is the process by which information from a gene is used in the synthesis of a functional gene product that enables it to produce end products, protein or non-coding RNA, and ultimately affect a phenotype, as the final effect.
