1. Average protein content in cow's milk
+3,3
-2,1
-1,5
-0,5
2. Recombinant proteins obtained from milk of transgenic animals
+human protein With
+alpha-1-antitrypsin
+chymosin
-hemoglabin
3. A clone is understood as
-numerous offspring of one original individual having an identical phenotype
-numerous offspring of several parental forms having an identical genotype
+numerous offspring of one original individual having an identical genotype
-numerous offspring of one original individual having an identical phenotype, but a different genotype
4. The main directions in animal cloning
+transplantation of nuclei from somatic cells into an enucleated egg
+obtaining homozygous diploid descendants
+creation of parthenogenetic animals
5. Medicines in the world practice obtained from transgenic animals are presented
+blood clotting factors, which are indispensable for such a disease as hemophilia
+tissue plasma-gene activator used for venous thrombi, pulmonary arteries
+human protein With
+monoclonal antibodies
6. The year of Belarus' accession to the Cartagena Protocol
+2002
-2009
-1999
-1985
7. As a rule, direct gene transfer to plant cells can be carried out by
+biological ballistics
-microinjections
-chemical
8. Disadvantages of biological ballistics as a way of transferring genes into plant cells
-applicable only for dicotyledonous plants
+there are multi-copy inserts, the introduced gene constructs are partially destroyed
-low frequency of transformations
9. The process of agrobacterial transformation is initiated first of all
-treatment of the plant with alkali
-treatment of the plant with acid
-treatment of the plant with an ice solution of CaCl2
+damage to the plant, for example, by mechanical means
10. The integration of T-DNA into the plant genome is accompanied by a deletion of DNA length (bp)
+10-100
-100-300
-5-10
-more than 300
11. Reporter genes are used to study
+regulatory elements of genes
-combinations of gene alleles
-structures of mobile genetic elements
12. To obtain multicellular GMOs, the desired gene is first transformed
-into a multicellular organism
- into a multicellular or unicellular organism
+into individual cells that will become a full-fledged organism
13. To obtain transgenic animals, they are most often used
-unfertilized eggs
+fertilized eggs
-somatic cells
- stem cells
14. Methods of cultivation of plant cells in vitro
+on solid (agarized) nutrient media
+on liquid nutrient media
-in phosphate-salt solution
15. The callus should be understood as
+disorganized, actively proliferating tissue, which is represented by undifferentiated cells
-organized tissue, which includes only undifferentiated cells
-unorganized, proliferating tissue, represented by differentiated cells
16. A prerequisite for the process of dedifferentiation of primary explant cells for most plant species is the content in the substrate
-CaCl2
+auxins
-NaCl
+cytokinins
17. Auxins initiate
-the process of cell differentiation
+the process
of cell dedifferentiation -division of dedifferentiated cells
18. Cytokinins initiate
-the process of cell differentiation
-the process of cell dedifferentiation
+division of dedifferentiated cells
19. Protoplasts are obtained from
+ leaf parenchyma cells, callus cultures, suspension cultures
-bacterial cells
-cellulose shell of a plant cell
20. Cellulose shells of plant cells are dissolved using
-restriction polymerase

- acids
+cellulase
21. In order not to damage the internal contents of the plant cell during and after the removal of cellulose shells, it is necessary to add to the nutrient medium
+osmotics
-cellulases
- auxins
- cytokinins
22. Under the action of osmotics, the protoplast
is destroyed
+shrinks, lags behind the cell walls, taking a spherical shape
-recovering
23. Cultivation of plant cells
+in many ways similar to the cultivation of microorganisms
-radically different from the cultivation of microorganisms
-identical to the cultivation of microorganisms
24. Methods of plant regeneration in culture in vitro
+embryogenesis
- parthenogenesis
+organogenesis
-cloning
25. What you can find out from the maps of genetic coupling
-combination of alleles
-the mutual arrangement of chromosomes
+the location of genes within the chromosome and the relative distance between them
26. What should be understood by the genome map
+a graphical scheme that makes it possible to navigate within the genome, to search for important sites
-schematic arrangement of genes on chromosomes, relative distance between them
-karyotype
- genetic population
27. The establishment of allelomorphs of the PDRF locus on the chromosome is understood
as transformation
-expression
+genotyping
28. According to the physical map of the chromosome, you can find out about
+gene locations
-allelic variants of the gene
-distribution of allelic variants of genes in populations
29. The predominance of auxins over cytokinins in the nutrient medium, as a rule, contributes to the formation of
- stem
+root
-leaves
30. The predominance of cytokinins over auxins in the nutrient medium, as a rule, stimulates the formation of
+stems
-root system
-leaves
31. Animal somatic cells exhibit totipotence at
a late stage
+early stage
- totipotence is uncharacteristic for them Psychic readings Psychic Readings In Orem Psychics
