No, it's all DNA. The genetic material of eukaryotes is DNA (e.g., yeast), prokaryotes (e.g., bacteria), but viruses can be DNA (e.g., AIDS) or RNA (tobacco mosaic virus) or proteins (paravirus), but viruses are not eukaryotes. Nor is it a prokaryotic organism.
-
Couldn't be more wrong! First of all, eukaryotes and prokaryotes are both organisms with a cellular structure, and the biological genetic material with a cellular structure is DNA RNA also has as genetic material, but it is not the main carrier of genetic material, the main carrier is DNA, RNA is a biological material with a cell-free structure, such as viruses, etc., and everyone knows that HIV (AIDS) is RNA as genetic material.
-
Eukaryotes use DNA as the main genetic material in the genetic process, and RNA mainly plays the role of expression inheritance (direction) in the genetic process. Whereas, prokaryotes use RNA as the main genetic material in the process of inheritance.
-
The genetic material of all organisms with a cellular structure is DNA, and organisms with a cellular structure contain both DNA and RNA, and for organisms that contain both DNA and RNA, DNA is the genetic material, and viruses contain only one nucleic acid, either DNA or RNA, and for viruses that contain only RNA, RNA is the genetic material.
-
Wrong, except for viruses, some of the genetic material is DNA, if other organisms contain both DNA and RNA, their genetic material is DNASo it can't be used"or".
-
Wrong. It's all DNA, only the genetic material of the virus is DNA or RNA.
-
No, as long as there is a cell structure, the genetic material is DNA.
-
This is not true, only some viruses use RNA as their genetic material.
-
Wrong. According to the latest scientific discoveries, there are virus-like viruses that use proteins as genetic memory material.
-
Prokaryotes contain two types of nucleic acids, DNA and RNA, but their genetic material is DNA
Therefore, a
-
Both eukaryotic and prokaryotic cells use DNA as their genetic material, and prokaryotic cells have both DNA and RNA. With the exception of some viruses, the genetic material of the rest of the viruses and all organisms with typical cellular structures is DNA.

The DNA differences between eukaryotes and prokaryotes: eukaryotic DNA has introns, and the introns need to be excised after transcription, while prokaryotes do not have an enzyme system to excise introns, and the correct protein cannot be synthesized if the introns cannot be removed;
Differences in protein product expression: Prokaryotes do not have an endomembrane system and cannot properly and efficiently modify and fold the synthesized polypeptides. In addition, the ribosomes of prokaryotes differ from those of eukaryotes, and the synthesized polypeptides may also be affected.
Different regulatory mechanisms: prokaryotes can regulate gene expression through operons, but this mechanism is ineffective against eukaryotic genes; Eukaryotic genes need to be regulated by introns, and they require complex signaling systems to regulate.
Play it yourself.

Hello, there are introns and exons in the DNA of eukaryotes, and when proteins are expressed in eukaryotes, there are Golgi apparatus and endoplasmic reticulum organelles for processing, and the peptide chains expressed by the introns in the gene are partially cut off, and the peptide chains expressed by the exons are partially connected, which is the so-called primary structure of active proteins, which are formed by folding proteins with a certain spatial structure of activity.
However, there is no distinction between introns and exons in prokaryotic genes, and all genes are partially expressed to form active proteins, even if the genes of eukaryotes are expressed in prokaryotes, they cannot be sheared, and active proteins cannot be formed. Therefore, human insulin cannot be synthesized in prokaryotic species, and proteins containing sugar side chains cannot be expressed in prokaryotes. It is not possible to leave the gene unprocessed.
-
Active proteins refer to proteins with complex spatial structures, which only form peptide chains on ribosomes, while complex structures are processed on the endoplasmic reticulum and Golgi apparatus. Whereas, eukaryotes have these organelles but the endoplasmic reticulum and Golgi apparatus are absent in prokaryotes. Therefore, the expressed protein has no biological activity.
-
Prokaryotic cells are also DNA which is the genetic material. And once DNA is present, DNA is the individual's only genetic material. Sometimes doing multiple-choice questions will lead to the statement that DNA is the main genetic material of cells, which is wrong.
Most of the genetic material with RNA as the genetic material are viruses, viruses are not cells, generally speaking, prokaryotic cells are inherited from DNA.
Bacteria are prokaryotes, and the fundamental difference between prokaryotes and eukaryotes is that there is no formed nucleus in prokaryotic cells, and at least in all the bacteria found so far, there is no formed nucleus, so bacteria must be prokaryotes.
There are cells to verify eukaryotes, and there is no nucleus is the most fundamental difference between prokaryotes.
Eukaryotes eukaryotes are organisms made up of eukaryotic cells. Including the kingdom Protists, Fungi, Plants, and Animals. Definition Eukaryotyotes are a general term for all unicellular or multicellular organisms whose cells have a nucleus, and it includes all animals, plants, fungi, and other organisms with complex subcellular structures surrounded by membranes. >>>More
