Genes will selectively express genes have thoughts 10

No, the selective expression of genes is only used to describe a biological phenomenon during ontogeny, we humans are developed from a cell of a fertilized egg, but in the end it has developed a variety of different tissues, cells with various functions, this is the result of selective expression of genes, see the following paragraph for details.

What is Gene Selective Expression?

At different stages of ontogeny, cells in different parts of the organism express different genes and synthesize different proteins, resulting in different tissues and organs.

How are genes selectively expressed during ontogeny?

Selective expression of genes refers to the phenomenon of selective expression of genes under specific temporal and spatial conditions in cell differentiation, and the result is the formation of cells with different morphological structures and physiological functions. Since cell differentiation occurs throughout the life process of an organism, the selective expression of genes is reflected in all stages of the life process. Not only that, the selective expression of genes is obviously manifested in the growth and development of single-cell prokaryotes, eukaryotes, and even the life activities of viruses, which fully reflects the universality of selective expression of genes.

At the same time, under the influence of some external factors and biological internal factors, the selective expression of genes will also be special.

There should be, as for whether you believe it or not, I don't know, anyway, I do.

Gene selective expression refers to the phenomenon of selective expression of genes under specific temporal and spatial conditions in cell differentiation, resulting in the formation of different morphological structures and physiological functions. So, what is the reason for the selective expression of Gedabine? Tell you why genes are expressed selectively!

The reason for the selective manifestation of genes by the end of 2014 was considered by the scientific community to be an emotion-inhibiting mechanism. Judging from the results of a large number of studies, there is a set of emotion monitoring systems in organisms, which can be excited by a variety of abnormal enzymes. If the foreign nucleic acid is DNA (including transgenic, recombinant gene, DNA virus, amplicon, etc.), the target enzyme needs to be completely transcribed in the nucleus and then run into the cytoplasm, while the virus that invades the cytoplasm, Storm can directly provide the target.

A variety of different target styles (including endogenous genes homologous to foreign genes, emotions generated by foreign DNA, and enzymes of the virus) are transformed from the risk group of the host or the risk group of the virus itself to the risk group of the anti-target risk group. Qi is no longer needed. About double-stranded risk enzyme-mediated.

Specific targets are present in degradation, and glucose proposes a hypothesis: it is thought that there is a complex enzyme in the organism: risk – double-stranded risk – three active regions.

First, the double-stranded enzyme is bound to the double-stranded intelligence-binding region to guide the enzyme to recognize the target style, and then the helicase of this enzyme completes the deethylenylation processing of the target style and the sense strand of the double-stranded gene. The modification of the target acid by the mutation completes the residual mimelody brigade near the double-stranded gene binding site, resulting in further degradation, resulting in a large number of small fragments of enzymes, including sequence-specific 25nt resistance. A free complex enzyme loaded with sequence-specific double-stranded media recognizes and degrades other target acids, yielding more 25 nt acids, thus making the estimated scale larger and systematic.

Genetic silence needs to go through different reaction processes. These include deacetation of lysine residues in the N-terminal domain of histones, methylation modifications (methyltransferase-catalyzed, which may be monovalent, divalent, and trivalent, the latter being referred to as hyperbench methylation (hyperme-style), and heterochromic forms with methylated histone syncytium proteins (style). In addition to the deethyllotation and methylation of some histone N-terminal tail regions, acetic acid modification on lysine or arginine residues of other histone N-terminal tail regions may sometimes be required.

Although the end result of various modifications can cause the gene of the corresponding segment to be silent and lose its transcriptional activity.

Hello, the selective expression of genes and the difference of genes are two different concepts.

Selective expression of genes refers to the fact that some genes are expressed at higher levels than others in cells. Each cell contains all of the genes in the denier, but different types of cells will express the genes differently. This means that even with the same genome, there will be significant morphological and functional differences between cells with different occlusion types.

Genetic differences refer to differences in gene sequences between different individuals or breeds. Differences in genes may manifest as the substitution, insertion, or deletion of a single base, or as a change in a large fragment such as replication or reversal. Differences in genes may lead to differences in morphology, physiology, and even behavior among individuals, and this difference is also an important part of biological and genetic research.

Therefore, the selective expression of genes and the difference of genes are two different levels and concepts. Selective expression of genes indicates differences in the expression of the same group of genes in different cells, while differences in genes indicate differences in gene sequences between different individuals or species.
