What Specialized cells regulate the expression genes because they?
The genome contains several genes, all of which do not have to be switched on simultaneously. When a cell has to become specialized, it has to switch on certain genes and switch off the transcription of others. This mechanism of keeping a check on the genes being expressed at any point of time is referred to as gene regulation. A neuron, for example, will have a certain set of genes switched on, which is different from the genes switched on my a sarcomere (muscle cell). Gene expression dictates the properties and characteristics of specialized cells in the body
What is the characteristic of a cell membrane that controls which substances that can either enter and exit the cell?
Selective permeable
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 is the membrane permeability?
means that the cell membrane has some control over what can cross it, so that only certain molecules either enter or leave the cell
What controls gene expression?
•A gene is a segment of DNA which codes for a specific protein. Through transcription and translation, a protein is produced and then is used for cell processes.
Which describes the process through which certain genes within a cell are activated to produce proteins while others are not?
gene expression

What controls the way in which a zygote differentiates?
Selective genes are turned on and off, depending on the fate of the cell.
How are dieseases inherited?
This means that you inherit certain genes from your parents; these genes can predispose you to a certain diseases. For example, you may be more vulnerable to certain bacteria, or the genes may directly related to some defect, such as sickle-cell anemia.This means that you inherit certain genes from your parents; these genes can predispose you to a certain diseases.

The kinds of proteins produced you a cell are related to what?
The types of proteins produced by the Cell are those that are allowed by the Expression of the Genes in a cell's Dna.
What can sometimes influence expression of genes?
Several factors determine the final outcome of gene expression. They include the cell's environment, the presence of other cells, and the timing of gene expression. hope this helped! -Steph
What are three categories of genes that when mutated can lead to tumor formation?
· 1) Genes involved in cell division · 2) Oncogenes o Dominant-acting stimulatory genes o Normally low levels or expression is turned off o Mutation causes increased/hyper expression · 3) Tumour suppressor genes o Recessive-acting genes o Normally expressed to inhibit cell division o Mutation causes defects in product or no expression
What are genes used for?
Genes are used to produce a certain protein or protein components for the cell and as a means to transport this information to the next generation.
When would you want to use selective media?
Selective Media - Our cell membrane has a selective permeable property. This type of membranes are important when we want to allow certain sized particles to enter while restricting other sized particles to enter our cell. Selective permeable membrane is of great use in biological samples.
What is the characteristic of a cell membrane that controls which substances that can either enter and exit the cell?
Selective permeable
DNA microarrays have made a huge impact on genomic studies because they?
allows the expression of many or even all of the genes in the genome to be compared at once
What is the role of environmental factors in cell differentiation?
Environment factors in cell differentiation influence the expression of genes. A few examples of environmental factors are chemicals, drugs, and temperature.
