Is the DNA of the kidney cell the same as the DNA of the skin cell?

The base pair sequence is identical in every cell of a given human (barring oddities like chimeras).\n\nWhat differs is the genes that are active and inactive.  Sometimes base pair methylation is used for that; sometimes, binding of the DNA to histones or other protein (and probably RNA) molecules turn off or turn on genes, etc.  It's sort of like a piano--all the keys are there for every performance.  It's just that some are struck, and others not.  (And you'd probably rather listen to someone other than me playin' it...)  Depending on the order of the striking of the keys, and the combinations of keys struck at different times, you get different pieces of music.\n\nSimilarly the sequence and pattern of genes turned on and off generates different kinds of cells, even though the DNA is essentially identical.

Yes.  DNA is transcribed into RNA, and RNA is translated into proteins.  \n\nI always kept that straight by thinking of transcription as like taking notes when someone is talking (same language) and translation as translating those notes into another language.  Going from DNA to RNA you're going to use the same building blocks (bases - purines and pyrimidines)or the same "language", but going from RNA to proteins requires going from one building block to another (bases to amino acids), or a different language.

One of the most obvious differences between the DNA of different species is the number of chromosomes.  If you have intact cells, you can do a DNA smash and stain and see how many chromosomes there are - for example dogs have 78 chromosomes, while humans have only 46.   Molecularly, there is no difference, besides a few genes which differ in sequence.

DNA contains a complete blueprint for the body, not only for growth but also repair.  Although each cell contains a complete copy of the original DNA, the particular cell is differentiated from the original DNA containing cells at conception and can only make cells of a particular type (blood, skin, bones, brain, etc.).  During growth, cells divide because the blueprint has not been completed.  Much later little growth is required except perhaps hair, skin and gut lining, etc. and DNA splits and reproduces to make repairs (to patch wounds, etc.) to restore the blueprint construction to normal best it can.  Differentiation may occur because particular cells are influenced by surrounding cells.  Therefore a new toe never grows within a damaged eye.

Neither.  DNA doesn't change.  And the heart only pumps the blood, it doesn't make or act on it.

Yes. epithelial cells along with white and red blood cells can be excreted in urine as well as excreta. And the bacteria that is in the excreta has its own unique DNA that can be tested and compared to other bacterial DNA.

DNA = deriboneucleic acid\nRNA = riboneuclic acid\nRNA is present in each human cell in the lipoprotein (outside the cell) part. \nDNA is present in the neucleus of the cell. to be more specific, in the chromosomes inside the neucleus of the cell. so, it is only the DNA that carries the genetic property to the offsprings.\n\nas for your project, you can surely include it as a chapter.however make it sure that it is not too lengthy to dominate the main subject.\nyou can also include a chapter related to "clones and cloning". that could help you in showing it more clearly that its only the DNA that helps to transfer the genetic property to the young ones.\nif you need any further help in your project, you can contact me at \n\nmangeshome1982@yahoo.co.in\n\ngood luck.

Each cell contains our DNA makeup, it is protected inside the cell from bacteria, viruses and other harmful agents.  Without DNA our body would not be able to replicate and replace the cells which make up for example our organs or skin.  We are constantly producing new skin cells to replace the ones that we shed off every second.

DNA has already been cloned, so your question is meaningless. This was done in bacteria over 40 years ago, and is how human insulin is now produced en masse.

Yes, the human body has similar sensory cells inside the body. However, there are also many other types of sensory cells inside us that aren't like the ones on our skin. Some of the cells in certain places (the large and small intestine, for example) are only sensitive to stretch, and are essentially numb to lacerations or other stimuli. Likewise, infections in certain areas (GI tract, once again) are often not noticed until other areas with different kinds of nerves become infected (such as the peritoneum). Basically, the answer to the question is yes, we have sensory cells similar to skin ones, and no, we have other kinds as well.

DNA is what makes up our genes.  It is several long chains (polymers) of molecules that contain a 'chemical code' that the body uses to make proteins (proteins are many types of molecules that are necessary for the body to make and run itself).  These long chains of DNA are grouped into 23 different chromosomes.  You have two pairs of each chromosome - one set of 23 from your mom and the other set of 23 from your dad.  So, in total, you have 46 chromosomes in each cell.\n\nEach cell in your body has the same DNA.  But a liver cell is different from a skin cell, etc.  That is because each cell type has access to only certain genes in your DNA (to make the proteins needed specifically for that type of cell).\n\nStructurally, DNA looks like a flexible ladder (like a rope ladder).  The runs of the ladder (the sides) are the long chains or polymers and consist of a sugar group connected to a phosphate group, connected to the next sugar group, and so on.  Between these side chains are pairs of 'bases' - Adenine, Thymine, Guanine, and Cytosine (A T G  C).  These are the actual code that contains the information in your genes.\n\nThe 'ladder' of DNA twists around itself to form a shape called a 'double helix'.\n\nI hope this is helpful to you.  Good luck!

Check it out... I can answer seriously...\n\nI gave my kidney away to a friend 8 or 9 years ago. Honest and no joke. Our tissue matches up like brothers and he has not had an issue with rejection. My kidney dr. is all pissed at me though for not drinking enough water through the day... kidney stones and all...\n\n I have often wondered about the tissue though. What is the DNA of the grafting and connecting tissue from my old kidney to his body anyway?\n\n I won't even go into the spiritual side of it... Yes the Bearded One has a spiritual side...\n\n I'm watching this question though. Nice to know I'm not the only one who has thought about this...\n\nIf you ever want to give up a kidney however, Swedish Med on the hill in Seattle is THE BEST!!!\n\n The actually made me a steak, Rare! AT 4:AM!!!\n\nI also proposed to a nurse while in the morph drip... that was fun.\nGetting the cath out was a pain...\n\n But I'd do it again.
