Mesenchymal stem cells are the most crucial pluripotent cells located in bone marrow and peripheral blood. These cells turn into osteoblasts and the markers for confirmation are

• RUNX2 gene
• Alkaline Phosphatase
• Osteocalcin
• All of the above

Recently Glycoproteins are considered to be highly significant in biomarker identification. How would you isolate these proteins from mouse Liver tissues?

• ConcovalinA
• Lectins
• Agarose hydrazide
• All of the above

In the human gene for the beta chain of hemoglobin, the oxygen-carrying protein in the red blood cells, the first 30 nucleotides in the protein-coding region are as shown here. 3'-TACCACGTGGACTGAGGACTCCTCTTCAGA-5 ' What is the sequence of amino acids in this part of the beta-globin polypeptide chain?

• MetValLeuThrProGluGluLysSer
• MetValHisLeuThrProGluGluLys
• MetValHisLeuThrProGluGluLysSer
• MetValHisLeuThrValGluGluLysSer

The chemical colchicine is a “spindle poison” that interferes with the organization of the spindle. Somatic cells undergoing division in the presence of colchicine arrest at metaphase. Eventually the splitting of the centromeres that is characteristic of anaphase occurs, but cell division does not take place. If a cat cell with a normal diploid complement of 38 chromosomes undergoes one round of the cell cycle in the presence of colchicine, what is the expected number of chromosomes in the resulting cell?

• 98 chromosomes
• 96 chromosomes
• 98+X chromosomes
• 98 +Y chromosomes

Would mutation A be dominant or recessive to the wildtype allele

• Mutation A is cis-dominant to the wildtype allele
• Mutation A is an Oc mutation
• Mutation A is an Oc mutation and is cis-dominant to the wildtype allele
• None of the above
• Option 5

The Human Body dosenot produce
