Chacha told you.
The genetic material of all cellular organisms is DNA.
Some viruses have DNA as their genetic material, for example, bacteriophage viruses.
Some viruses have RNA in their genetic material, such as tobacco mosaic virus (the mode of genetic information transmission is: RNA self-replication, direct translation into protein) and SARS virus, HIV, hepatitis B virus, influenza virus (the genetic information transmission mode of these four viruses is: RNA reverse transcription into DNA, then it will be transcribed and translated into protein, and RNA will also self-replicate).
The most special is the Nguyen virus, whose genetic material is neither DNA nor RNA. It's a protein.
-
The genetic material of all eukaryotes, prokaryotes is DNA
Most viruses are also DNA viruses, such as herpes virus, T-even phage.
Only a small number of RNA viruses, the special is that RNA viruses have a complete set of reverse transcriptase system (this contradicts the high school biological statement, but viruses absolutely exist enzyme system), reverse transcribing RNA into DNA and integrating it into the host's DNA strand for replication, transcription, translation, typical coronavirus, influenza virus, HIV, H5N1, etc.

Genetic material is the material that transmits genetic information between parents and offspring.
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 genetic material is RNA: RNA viruses.
The genetic material is RNA and DNA: eukaryotes and prokaryotes, eukaryotes have DNA in the nucleus, RNA inside the cytoplasm and ribosomes, and DNA inside chloroplasts and mitochondria
The circular DNA molecule of prokaryotes has DNA and RNA on the ribosome

1.The vast majority of biological genetic material is DNA
2.Some viral genetic material is RNA, mainly tobacco mosaic virus, HIV, SARS, etc. in high school (generally the viral genetic material expressed by abbreviations is RNA, which is basically the case in high school).
3.Some special prion genetic material is proteins, such as the mad cow virus, but if you're only in high school, don't bother with that.

The genetic material of cellular organisms is DNA. In noncellular organisms, part of the organism's genetic material is RNA (e.g., HIV) and part is DNA (e.g., bacteriophage).
-
Animals and plants are DNA, and some viruses are RNA, such as: AIDS, SARS, tobacco mosaic virus, etc.
The general topic will tell you, don't worry.
-
The genetic material of animals and plants is DNA, and the genetic material of the SARS virus is RNA
-
The core "high school biology" DNA is selected to summarize the main genetic material knowledge points.

-
DNA is the main genetic material, and now most organisms use DNA as their genetic material, and a small number of organisms use RNA as their genetic material.

Proof of bacteriophage.
DNA is the genetic material. As for DNA, the main genetic material is for all organisms (some viruses have genetic material that is RNA, tobacco mosaic virus, HIV virus.
Plantain virus, etc.).
The genetic material of all organisms with cellular structure is DNA

Because sulfur-35 labels bacteria, not phages, the supernatant (protein shell) is non-radioactive, while the precipitate (bacteria) is radioactive.

A. Both the nuclear genetic material and the cytoplasmic genetic material are DNA, and A is wrong;
b. "Transformation experiment of Pneumococcus" and "Experiment of bacteriophage infection of bacteria" both proved that DNA is genetic material, B is wrong;
c. The genetic material of eukaryotes, prokaryotes, and most viruses is DNA, and the genetic material of a few viruses is RNA, C is correct;
d. The genetic material of cellular organisms is DNA, and the genetic material of non-cellular organisms is DNA or RNA, and D is wrong
Therefore, c
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.
Absolutely. There are chromosomes in the nucleus, and there is DNA on the chromosomes, and DNA is the genetic material.
The production of biomass pellet fuel requires a lot of equipment, which can not be solved by a machine, and the amount of equipment used depends on the situation of raw materials, as well as the requirements for the degree of automation and environmental protection.
