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.
Why are some cells brain cells and others skin cells when the DNA is the same?
All body cells have the same DNA. They all play different roles because the brain sends them signals to do so. You can't have them all doing the same thing. Ex: If you only have skin cells, then what cells will make up your heart or liver or bones?
Why are all genes not active all the time?
Genes are not active all the time because different genes are needed for different functions in the body. The process of gene regulation allows cells to control which genes are turned on or off at any given time, allowing for the proper functioning of the body's processes.
What characterizes the independent assortment of genes into gametes?
The independent assortment of genes into gametes is characterized by the random distribution of different genes during the formation of reproductive cells. This process results in a variety of genetic combinations in offspring.
Genes located in different regions of the body during embryonic development may be which turned on and off never turned on turned on and left on activated for different times in different cells or all?
Genes located in different regions of the body during embryonic development may be turned on and off, activated for different times in different cells. This dynamic regulation helps to control cell differentiation and tissue formation.
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 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.
Do different kinds of cells in an embryo have different sets of genes?
No. With the odd exception (eg. mature red blood cells because they have no nucleus) every cell in a multicellular organism has the same set of genes. What gives the cells their different character, their phenotype, is which of these genes are expressed at any given time.
Are all genes in an organism being transcribed and translated in all cells?
No. This is why you have different types of cells.
Why are some cells brain cells and others skin cells when the DNA is the same?
All body cells have the same DNA. They all play different roles because the brain sends them signals to do so. You can't have them all doing the same thing. Ex: If you only have skin cells, then what cells will make up your heart or liver or bones?
Do eukaryotic cells have genes?
All cells have genes
Are the genes in daughter cells produced by mitoses the same as or different from the genes in the original cell?
The genes in daughter cells produced by mitosis are the same as the genes in the original cell. Mitosis is a process of cell division where the genetic material is replicated and evenly distributed between the daughter cells, ensuring that they have an identical genetic makeup to the original cell.
What are two ways sex cells different from other cells?
it helps the genes more and helps with more chromosome
Why do different types of cells arise in your body?
different genes are switched on and off in each type of cell
How do genes affect cells?
Genes tell cells how to make proteins.
Muscle cells and nerve cells in one species of animal owe their differences in structure to?
Having different genes. Expressed.
Which genes are present in your liver cells?
All your genes are present in your liver cells
