What is the difference between eubacteria, archaea, fungal genomes?

Archaea, bacteria, and eukaryotes.

In terms of cell structure and metabolism, archaea are close to other prokaryotes in many ways.

However in gene transcription both molecular biology.

In the central process, they do not clearly exhibit the characteristics of bacteria, but are very close to eukaryotes. For example, the translation of archaea uses eukaryotic priming and elongation factors, and the translation process requires the Tata box-binding protein and TFIIB in eukaryotes

Archaeaa also have a number of other characteristics. Unlike most bacteria, they have only one layer of cell membrane.

The peptidoglycan cell wall is missing. Moreover, the vast majority of lipids in the cell membranes of bacteria and eukaryotes.

It is mainly composed of glycerides, while the membrane lipids of archaea are composed of glyceryl ethers. These differences may be due to adaptation to ultra-high temperature environments. The composition and formation process of archaeal flagella are also different from those of bacteria.

The phylogenetic tree based on RNA sequences shows three distinct clades: bacteria, archaea, and eukaryotes

First, the classification is different.

1. Fungi: The most common fungi are all kinds of mushrooms, and fungi also include molds and yeasts.

2. Protists: can be divided into three categories, algae, protozoa, and protobacteria.

Second, the characteristics are different.

1. Fungi: The cells of fungi have a cell wall containing chitin (also known as chitin, chitin, chitosan) as the main component, which is different from the cell wall of plants, which is mainly composed of cellulose.

2. Protists: Protists include simple eukaryotes (i.e., nuclei with a true nucleus and a nuclear membrane as the boundary), most of which are unicellular organisms, and some are multicellular, but there is no tissue differentiation. This sector is the lowest of eukaryotes.

No, bacteria and fungi are not the same. Although they are both microorganisms, they are very different in many ways.

Bacteria are unicellular destructive organisms with simple cell structures and no eukaryotic organelles (such as nucleus and mitochondria). They can survive in many environments, and there are some bacteria that can cause disease, but there are also many species of bacteria that are beneficial to both humans and the environment, such as helping to break down food and make medicines, etc.

Fungi are a class of multicellular organisms that have a much more complex cell structure than bacteria and have eukaryotic organelles. Fungi usually grow in the form of hyphae and can break down and absorb organic matter, including the tissues of other organisms. Some fungi are beneficial to humans and the environment, such as those used to make food and medicinal fibers, but there are also fungi that can cause diseases, such as Candida albicans and Candida albicans.

So, although bacteria and fungi are both microorganisms, they are very different biologically.

No, bacteria and fungi are two different classes of organisms. Bacteria are unicellular organisms, whereas fungi are multicellular organisms.

Protists: Unicelled non-fungal eukaryotes are all protists, including unicellular algae as well as unicellular animals.

Fungi: Ekaryotes that do not contain chlorophyll, plastid, and have a chitin cell wall are fungi.

Both protists and fungi are eukaryotes and have the commonalities of eukaryotes. The structural difference between fungi and protists is that the cell wall of fungi is made of chitin, and protists are either cellulose or have no cell wall. In terms of nutritional methods, protists are diverse, and fungi can only be saprophytic or parasitic, that is, they can only be heterotrophic.

In fact, it is very easy to distinguish and teach you a trick.

Bacteria: All the rods, balls, arcs, and spirals in front of the word "bacteria" are bacteria, and there is a special "lactic acid bacteria" (lactobacillus, the rod word is often omitted).

Fungi: yeast, shiitake mushrooms, reishi, penicillium.

Summary. Hello dear, glad to answer for you! To determine the species of the bacteria, it is necessary to analyze and compare the genetic information of the bacteria.

A common method is to compare the genome of a bacterium with that of a known bacterium and then determine the species of the bacterium with the highest similarity. In addition, the species of the fungus can also be inferred based on its morphology, physiological characteristics, biochemical characteristics, etc. It should be noted that due to the large number of species of bacteria, it may not be possible to determine the species by comparing the genome, and it is necessary to combine other information to make a judgment.

I only have the genome of this fungus, how do I know the species of the fungus?

Hello dear, I'm glad to answer for you with a smile! To determine the species of the bacteria, it is necessary to analyze and compare the genetic information of the bacteria. A common method is to compare the genome of a bacterium with that of a known bacterium and then determine the species of the bacterium with the highest similarity.

In addition, the species of the fungus can also be inferred according to its morphology, physiological characteristics, and biochemical characteristics. It should be noted that due to the large number of species contained in the fungus, sometimes the species may not be determined by comparing the genome, and it is necessary to combine other information to make a judgment.

Genome-wide.

Genome-wide.

The whole gene group refers to the sequence information of all genes of an organism, including genes encoding proteins and non-coding RNA genes. Whole genome sequencing is a technique that sequences the genome to obtain the complete genome sequence of an organism. In genome sequencing, genome sequence data can be obtained using three generations of high-throughput sequencing technology or other types of sequencing technologies of Hunger Training, which can be used only for gene function research, species evolution research, genomics research, etc.

I lost that bacterium, only the whole genome of this bacterium, there is no way to measure 16s, what should I do to know the strain of this bacterium.

If you only have the whole genome of a bacterium, but you don't have other information about the strain, such as morphology, physiological characteristics, biochemical characteristics, etc., then it may be difficult to determine the species of the bacterium. However, strain-specific sequence alignment, such as tajima, can be tried's d'The genomes were compared by value comparison and caliper sequencing to find sequences with high similarity to known strains. In addition, you can try to use some public databases to find information about this fungus.

For example, NCBI's Genbank and Ensembl databases both contain a large amount of strain information, including the crude gene group sequence, gene annotation information, molecular characteristics, etc., which can be compared with the genome sequence of the strain to determine the species of the strain.
