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

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?
All body cells have the same genes except for the sex cells (sperm and ova). They do not use the same genes. A muscle cell isn't using the same genes as a nerve cell does. Otherwise the muscle cell and the nerve cell would not be different nor do different things.
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?
yes every cell contain genetic material and it is the only info which cell inherits from parent cell and the very info. (genetic material) helps the cell to develop in its' real original form i.e it guide the arrangement of its' contents -( mitochondria, Nucleus etc. ) in the form in which they are found hence enabling the cell to survive in external environment. and if sometimes there is some adulteration in genetic material that cell inherits from parent cell then it led to some variations in structure of cell which sometime are the reason of evolution of a new species or Other-times May be the "cause" of the death of the cell ( As the body design formed by adulterated information-genetic material- is not able to sustain in the environment. )
How does DNA technology transfer bacteria genes from cell to cell?
DNA technology will transfer bacteria genes from cell to cell.
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.
Do bone cells express genes?
yes
