Which strand must be in rna and not dna

"Ribonucleotides", I think, you aren't giving us answer choices

Uracil is present in RNA and not in DNA

RNA includes cytosine and uracil as pyrimidine bases while DNA has cytosine and thymine. The difference is Uracil as Uracil is not present in DNA. Uracil is less expensive to produce than thymine, and may be used for its use in RNA. But in the case of DNA, uracil is readily produced by chemical degradation of cytosine.

glacial erosion, the picking up and movement of earth beneath a glacier, is also referred to as plucking. erosion and transportation of individual pieces of bedrock, especially large "joint block occur as a result of this glacial erosion. plucking is type of erosion in which rocks become frozen into the bottom and sides of the glacier.as the glacier moves downhill it 'plucks' the rocks frozen into the glacier from the ground.

it marks things for degradation via the proteasome. it alters there celluar location.
