You get the entire organism from the single fertilized cell. There should be no doubt that this process is conducted by your genes only. So all the cells of your body are made in very particular order by your genes only. After the individual is formed, the functions of the most of the genes is over. You can easily check the function of the particular gene by sacking the same in zygote. The very important genes, which are involved in primary steps, will create the serious disorders in that particular animal. In such case the animal may not even survive. He may not have some important organ or system like liver or cardiovascular system or respiratory system. Step by step the function of the gene becomes less and less important, but then that is enough to cause some disorder like mucoviscidosis or poly-cystic kidney disease, in the patient, with slight variation. There are more than enough permutations and combinations, to produce all types of cells in the body of all the organisms on the earth, past, present and future. That is why 98 % genes in humans are noncoding.
Some people call these sections "junk DNA" but more research has shown that they can play a significant role in controlling cell development.
In eukaryotes, the noncoding portions of DNA are called introns. Introns are removed during RNA processing, leaving only the exons to be translated into proteins.
they are non-coding mRNA sequence in a mRNA strand but are not found in DNA as they are removed during mRNA processing before the formation of protein
Noncoding sequences in eukaryote cells mean that, those sequences do not form the proteins. That means they are not expressed as proteins in that eukaryote.

How is the DNA in a prokaryote different from the DNA in a eukaryotes?
DNA in prokaryotic cells is usually circular while DNA in eukaryotes is usually linear. DNA in prokaryotes usually has fewer portions that dont code for something while eukaryotes usually have quite a bit of DNA sections that dont code for anything. The number of actual base pairs (the units that makeup DNA) that makeup eukaryotes is usually quite a bit more than the number in prokaryotic DNA.
Noncoding portion of DNA is composed of?
The noncoding portion of DNA is composed of several types of sequences, including introns, which are removed during RNA processing, and repetitive elements, such as transposons and satellite DNA. These sequences do not code for proteins, but play important roles in gene regulation, genome stability, and chromosomal structure.
Do eukaryotes have DNA?
Yes, eukaryotes have DNA. DNA is the genetic material found within the nucleus of eukaryotic cells, which contains the instructions for building and maintaining an organism.
What is Heterogeneous nuclear DNA?
Heterogeneous nuclear DNA is the DNA present in the nucleus of eukaryotic cells that is not organized into chromatin. It includes DNA sequences that are actively being transcribed and processed, as well as regions of repetitive elements and non-coding DNA. This dynamic pool of DNA plays a crucial role in gene expression regulation and cellular function.
Is DNA contained within a nucleus for both prokaryotes and eukaryotes?
No, in prokaryotes like bacteria, the DNA is not contained within a nucleus. Instead, it is found in a region called the nucleoid within the cell. Eukaryotes, on the other hand, have their DNA located within a membrane-bound nucleus.
Do exons contain noncoding DNA?
Exons are the portions of a gene that code for the final protein product and typically do not contain noncoding DNA. Noncoding DNA is more commonly found in introns, which are the intervening sequences between exons.
What is the significance of noncoding DNA to DNA identification?
Noncoding DNA, also known as junk DNA, does not code for proteins but can contain unique variations that are specific to individuals. By analyzing these variations in noncoding DNA regions, forensic scientists can create a DNA profile for identification purposes, as these variations are highly specific to each person. This can be particularly useful in cases where coding DNA is not available or is not as informative for identification.

How is the DNA in prokaryotes different from from the DNA in a eukaryotes?
dna in eukaryotes is located in the nucleus
What part of a DNA molecule contains the instruction of making chromosome packaging proteins?
In prokaryotes the genes directly specify proteins.In eukaryotes the exons within the genes specify proteins, the introns within the genes are noncoding DNA that alternate with exons and are spliced out in the process of transcription to messenger RNA.
Do eukaryotes have DNA?
Yes, eukaryotes have DNA. DNA is the genetic material found within the nucleus of eukaryotic cells, which contains the instructions for building and maintaining an organism.
Where is the DNA in prokaryote in a eukaryote?
DNA in prokaryotic cells is usually circular while DNA in eukaryotes is usually linear. DNA in prokaryotes usually has fewer portions that dont code for something while eukaryotes usually have quite a bit of DNA sections that dont code for anything. The number of actual base pairs (the units that makeup DNA) that makeup eukaryotes is usually quite a bit more than the number in prokaryotic DNA.
What stores a molecule called DNA?
In eukaryotes, DNA is stored in the nucleus. In prokaryotes, the DNA is in the cytoplasm, though it may be bunched up in a structure called a nucleoid, which has no membrane around it.
A segment of DNA that provides the code for creating protein molecules is called what?
They are called sense DNA. On the other hand, portions which do not code for proteins are called junk DNA or non-sense DNA.
Durning cell division what structures do the DNA of eukaryotes bunch into?
During cell division the structures that the DNA of eukaryotes bunch into are the chromosomes.chromosomes
