All cells have DNA strands in the nucleus, except mature red blood cells which don't have nuclei.
No. The amount of DNA in human sperm cells is half of the amount found in body cells.
Somatic cells (human body cells) have 23 pairs of chromosomes for a total of 46
human body system
The cells hereditary system is the DNA of the human body.
Somatic cells are body cells which are important part of the body's multicellularity and function. So they should have same DNA code in order to maintain a balance in the functioning of the body. And except sex cells (gamates) all the cells of human body (i.e. somatic cells) have the same DNA code. Another reason for this is mitosis. As body cells arise from mitosis, the division is conservative and doesn't involve any process of inducing variation in the cells, hence all the cells originating from it have the same DNA code.
The answer is NO. You can modify a particular part of the DNA by mutation but an entirely different DNA cannot be incorporated into another DNA simply because DNA is present in each nucleated cell of the body and as there are millions and millions of such cells, its not possible to do it. :)
There are well over sixty trillion cells in the human body. The total amount of molecules located in all the cells of a human body can only be roughly estimated.
In one human cell, there are 2 metres of DNA. Which means that a human has about 200 trillion metres of DNA in their entire body. No... theres 3.6m of DNA per cell
Red blood cells
Actually DNA is present in the nucleus of each and every cell of the human body.
The replication of DNA forms new DNA which form new cells when put in the cells of new nucleus's. The body continuously needs to produce new cells through mitosis for growth and repair and therefore without DNA replication these new cells would not be able to be made, which are needed in the human body.
Since human body cells (like muscle cells) contain twice the amount of DNA present in human gamete cells, roughly 1.1 pg of DNA can be expected out of human gamete cells
