First of all DNA is not a cell. Second of all if DNA was all the same then we would also be the same in thought, apearance, and function. The only time DNA is the same is when it makes up a multicelled organism (or if a Organism is cloned or for a spieces of unicelluar organisms). This was explained by a seven year old,
For the most part, all cells within a single organism have the same set of DNA and genes. Cells in different parts of the body express genes differently, which is what allows the different cell types to exist.Certain cells within an organism may develop mutations in their genetic information, thus resulting in cells that do not have the same DNA and genes. An example of this is cancer. In addition, different cells may silence one chromosome and only express the genes in the other. This is the case in females, which have two X chromosomes (one from their mother and one from their father). In each cell, one of the X chromosomes is randomly silenced, so the genes expressed in different cells will vary depending on which X chromosome is silenced and which is expressed.
yes, for instance, if you take any two cells from your body, they will have the exact same DNA structure
Yes, except for mutations that may have occurred.
Yes of course they do. They have similar genes
no
Unicellular organisms have only one cell for each organism. Multicellular organisms are organisms with more than one cell for each organism.
Single-cell organisms, also called protists (because they are placed in the kingdom Protozoa) contain all the devices necessary for life in a single cell. This would include devices for ingesting food, moving from place to place (in those that are motile), and eliminating waste, and possibly even defence mechanisms. The one cell of these organisms is not dependent on any other cell to survive. Human cells, on the other hand, each perform specific functions, are not self contained, and rely completely on the entire system, or a good part of it, for survival. A single human cell, removed from the body will not survive long. Ray
The statement which best compares a multicellular organism to a single-celled organism is their functions. While multicellular organisms use organ systems to perform life functions, single-celled organisms do not use organs for the life functions.
Because a single cell isn't very complex. The more cells an organism has, the more it can specialize it's cells, such as all the specialized cells that make up your brain, stomach, skeleton, muscles, etc. An organism that is made up of only one cell, that one cell has to do everything that each of our specialized cells do.
An organism is tetraploid if each autosomal cell contains 4 copies of each chromosome.
each hypha is exactly one cell thick.
Each organelle has a specific function
"Unicellular" refers to life, in which each organism only has a single cell.

No
Half the genetic information in a sex cell
organism is constituted of organelles.organelles are like mitochondria,chloroplast,golgi.......etc well to be more precise an organelle is an intercellular compartment in the cell in which different functions related to cells are performed. while an organism is a living thing made up of single cell or many cells and each cell is composed of different organelles
The statement which best compares a multicellular organism to a single-celled organism is their functions. While multicellular organisms use organ systems to perform life functions, single-celled organisms do not use organs for the life functions.
Exactly 1/2.
