Which of the following best describes an advantage of cloning?
MA_775_DIABLO [31]

Answer:

The correct answer would be "Can prevent genetic diseases".

Cloning refers to the process of making an identical copy of organism, cell or DNA fragments.

One of the applications of cloning is eradication or prevention of genetic diseases.

It is done by isolating the correct or functional gene and make copies of it in in-vitro conditions.

The gene or DNA fragment is then inserted back into the cell.

With advancement in cloning process and understanding of stem cells, cloning process also favors tissues and organ harvesting which also help in reducing diseases.

Which sequence correctly arranges the building blocks of life from largest and most inclusive to smallest and most specific?
netineya [11]

The right answer is chromosome > DNA > gene.

Living cell element, of characteristic shape and in constant number, located in the nucleus of the cell.

DNA, which is our chromosome, carries the genes . The DNA molecule, also known as deoxyribonucleic acid, is found in all our cells.

The gene is a piece of this DNA that corresponds to a particular genetic information that codes for a single protein. So it's a very small portion of chromosome.

The extracellular matrix (ECM) was regarded decades ago as an uninteresting set of proteins and unusual carbohydrates that were
IrinaK [193]

Answer:

(a) E-cadherin growth suppressor genetic factor are significantly active space of analysis in growth and tumorigenesis. The calcium reliant connections between E-cadherin particles are essential for the creation and conservation of supporter connections in parts of animal tissue cell-cell interaction.

CAMs admire the cadherin glycoproteins ordinarily perform because the adhesive that grips cells along and performance as necessary intermediaries of cell to cell connections. E-cadherins, on the superficial of all animal tissue cells, are joined to the simple protein bodily structure complete connections with catenin’s within the protoplasm

(b) scleroprotein synthesis is exclusive assumed its closing gathering phase. justify this declaration. The last part originates from the establishment of precise amino acids admire Glycine, aminoalkanoic acid and Hydroxproline. scleroprotein additionally has 2 unusual spinoff amino acids that don't seem to be straight introduced throughout translation.

Collagen consists of three handcuffs. The manacles are looped along to create a multiple helix. the method of scleroprotein synthesis happens principally within the cells of fibroblasts that are specialised cells with the most perform of manufacturing collagen and stroma. scleroprotein mixture happens each intracellularly and extracellularly.

 

c. Laminin could be a substance of integrin’s receptors. it's AN RGD theme that dilemmas to RGD compulsory sphere on receptor. So as to investigate whether or not the somatic cell composition is because of compulsory of laminin to integrin’s, ab initio it's to be verified, that integrin’s are profusely articulated on the somatic cell semipermeable membrane. This may be achieved mistreatment technique examination via antibodies or by template RNA appearance by RT-PCR.

The appearance of those integrin’s may be inhibited mistreatment RNAi by siRNA method. The siRNA can destroy the template RNA for the integrin because it contains a balancing arrangement to the mRNA. The damage of template RNA can source decreased macromolecule appearance. The cells will then be coated on the 3 glazed plates makeshift, laminin. If the cells provide spherical cells, formerly the somatic cell composition are going to be because of integrin-laminin collaboration. The cells may be gathered and testes for somatic cell indicators that designated distinction to neuronal composition. If no diversity indicators are specificed in laminin covered plates with distorted cells as likened to the management cells that rapid integrin’s, then it's laminin integrin communication that's chargeable for the somatic cell composition see, simple protein thread designs can even be deliberate on top of things and distorted cells produce on laminin covered plates by technique.

Another technique which will be utilized is to pelt the philosophy plate with changed laminin macromolecule that absences the RGD themes. The somatic cell cell appearances will then be plated and refined on the management laminin and changed laminin missing RFD themes. If the somatic cell composition isn't ascertained, then it may be over that laminin-integrin connections are concerned in growth of the somatic cell composition.

(d) Glycosaminoglycans (GAGs) are necessary electronic warfare parts, as a result of they're extremely charged polymers that powerfully dilemma aquatic and ions, making state in electronic warfare areas, and since they dilemma and confiscate physiologically necessary proteins.

Proteoglycans facilitate control trails that management vegetative cell fate, and so represent a wonderful tool to control these trails. Although their position, there's a scarcity of knowledge linking glycosaminoglycan construction inside proteoglycans with vegetative cell variation.
