If cordycepin triphosphate is added to a cell-free transcription reaction, the nucleotide is added onto the growing rna chain but no more nucleotides can then be added. the added cordycepin is always found at the 3' end of an rna. examine the structure of cordycepin and explain why it ends transcription.

1. true.2. true.3. true.4. false.5. true.the concept of darwin's theory of evolution involves the idea that there are limited resources in a given living environment and that the organisms which live within have variations in their genetic make up due to random mating. the ones with beneficial genetic variations can express certain traits which give them an upper hand in surviving and reproducing in the said environment compared to ones who may have a more disadvantageous variation in traits. over time, the organisms with an upper hand will survive and reproduce more frequently and pass on their beneficial genes while the others die. the result is evolution, where we observe (usually, but not always) eventually, phenotypic distinct changes.
