The enzyme telomerase is part protein and part RNA.
What would be the most likely effect of a large deletion in the gene that encodes the RNA part of telomerase, and how would the function of telomerase be affected? Select all that apply.

a. Telomerase would be unable to correctly associate with telomeres.
b. The catalytic center of telomerase, the polymerase, would be altered.
c. Telomerase would lose the ability to synthesize new telomeric sequences to extend the telomere.
d. Telomerase would be unable to proofread its DNA product but would still synthesize telomeres.
e. The telomerase enzyme would be able to make only a few telomeric repeats before falling off.

Option C and Option E

Explanation:

The effect of deletion in the gene that encodes the RNA part of telomerase is that telomerase would lose the ability to synthesize new telomeric sequences to extend the telomere and the telomerase enzyme would be able to make only a few telomeric repeats before falling off because RNA is dependent on DNA polymerase to add telomeric DNA to telomeres.

b

explanation:

increase soil erosion                                             reduce soil erosion

cattle grazing                                                         hydroseeding

deforestation                                                         contour plowing

                                                                                planting vegetation

plant roots basically hold the top soil

together and stop soil erosion because

in such situation top soil is not removed

during flood but cattle grazing causes

soil erosion because cattle consume the

grasses and herbs and top soil is exposed.

same situation occurs because of

deforestation, the trees and plants are cut

down to expose top soil which causes soil

erosion
