Answer #1

Ans- (IV). Germ line

Telomere is a special functional complex at the end of linear eukaryotic chromosomes, consisting of tandom repeating DNA sequences and associated proteins. Telomerase is a ribonucleoprotein that stabilizes telomeres of chromosomes in actively growing cell, and the ability of cell to divide over an indefinite lifespan may require the expression of telomerase. Telomerase activity is detected in over 90% human cancers from tissue specimen and normal germ cells, but none in normal tissue adjacent to the tumor.

n humans, red blood cells have a number of proteins embedded in the cell membrane. One type of protein, the Rhfactor, is controlled by a single gene and is either present or missing from the red blood cells. If present, the individual has the Rh+phenotype. If missing, the individual has the Rh-phenotype. Rh+is the dominant to Rh-. Suppose that, in the Welsh population, the frequency of the Rh-phenotype is 0.04. Using the Hardy-Weinberg equations, calculate the frequency of the Rh+allele.

The MN blood group is another blood group found on human red blood cells. There are only two alleles, M and N, which are codominant. In a population of humans there are 80 individuals that are MM, 150 MN, and 270 NN. Using the allele counting method, determine the allele frequencies for M and N.

Red and white blood cells develop from a common hematopoietic stem cell, which is large and nucleated. After cell differentiation and maturation, red cells no longer have nuclei and are very small, and white cells are nucleated, often large, filled with granules, and are capable of phagocytosis. Why do mature red blood cells look so different from their white counterparts?
