Genes result in a product (usually a functioning polypeptide, rRNA or tRNA) and have 4 levels or gene expression: transcriptional, post-transcriptional, translation, or post-translation. Gene Mutations are any alteration in the code of a single gene. There are three types: addition, deletion, and substitution. Examples:
TAC GGA ATG - original
ATA CGG CAT G - addition
ACG GCA TG - deletion
TAG GGC ATG - substitution
It can either be beneficial, deleterious, or have no effect at all.
Examples:
GAG = glutamate, GUG = valine, which is a sickle cell, animia
Stop codon = incomplete protein x-linked clotting disorder, nemophilia
Cells can regulate gene expression through a process called gene regulation, which involves turning specific genes "on" or "off" in response to internal or external signals. This regulation is controlled by a complex network of regulatory proteins and DNA sequences that determine when and where a gene is expressed. Signals from the cell's environment, such as hormones or growth factors, can trigger this process by activating specific genes and pathways.

What is a segment of DNA that contains the information necessary to express the inherited traits of an organism?
A gene is a segment of DNA that contains the information necessary to express inherited traits in an organism. Genes encode proteins or functional RNA molecules that carry out specific functions in the cell, ultimately determining an organism's characteristics.
Does a cell have only a few genes?
No, a cell can have thousands of genes. Genes contain the instructions for making proteins that carry out various functions within a cell. The interactions of these genes determine the cell's characteristics and behaviors.
If all cells in your body start out life with the same inherited information on how to build proteins then what caused the differences between a red blood cell and a white one Between a white blood?
The differences in cell type arise from the process of selective gene expression, which means that different sets of genes are activated or repressed in each cell type. This results in the production of specific proteins and ultimately determines the cell's function and characteristics. For example, red blood cells express genes that make them specialized for oxygen transport, while white blood cells express genes that make them part of the immune system.
Do all body cells activate the same genes?
No, different body cells activate different genes in order to carry out their specific functions. This is known as cellular differentiation, where cells become specialized to perform particular roles within the body. Each cell type will activate a specific set of genes needed for its specialized function.
Where are your genes located in a cell?
Genes are located in the nucleus of a cell, specifically within the DNA molecules found in the chromosomes. Genes are segments of DNA that contain instructions for building proteins, which are essential for the structure and function of cells.
How does DNA make a muscle cell different from a liver cell?
Muscle cells and liver cells have the same DNA, but they express different genes. This differential gene expression determines the unique characteristics and functions of each type of cell. Muscle cells express genes related to movement and contraction, while liver cells express genes related to metabolism and detoxification.
What role does the genes play in a cell?
i do not know mate
Why only certain cells produce certain products?
Control genes impede certain genes from expressing themselves and allow others to express themselves/ Thus a liver cell will have basically the same genome as a neuron, but will not express axon development and the neuron will not express bile development.

How are sex-linked genes express differently in the phenotypes of males in females?
i dont know.. im looking for the answer... XD
Does a cell in your stomach contain genes for brain cells?
No, a cell in your stomach does not contain genes for brain cells. Different types of cells express different sets of genes to carry out their specific functions in the body. Brain cells and stomach cells have different gene expression profiles to support their distinct roles in the body.
Do all cells express all genes?
No, not all cells express all genes. Cells regulate which genes are expressed based on their specific function and stage of development. This process, known as gene regulation, allows different cell types to perform unique functions even though they contain the same genetic information.
Is one enzyme enough to run a cell?
no. i would estimate a cell needs thousands per cell, depending on cell function. remember, different cell types have different functions, so they possess different suites of enzymes and express different genes.
How does DNA technology transfer bacteria genes from cell to cell?
DNA technology will transfer bacteria genes from cell to cell.
Do bone cells express genes?
yes
