Replication - The action of copying or reproducing something.
DNA replication of producing two identical replicas of DNA from one original DNA molecule.
Transcription - First step to gene expression, in which a particular segment of DNA is copied into RNA (especially mRNA) by the enzyme RNA polymerase. Both DNA and RNA are nucleic acids, which use base pairs of nucleotides as a complementary language.
1.) Transcription involved both DNA and RNA, whilst replication only involves DNA.
2.) Replication uses two identical replicas of DNA, whilst transcription is copied.
Hope I helped.
Enzymes are proteins, so the answer is enzymes
Gaseous cycles include those of nitrogen, oxygen, carbon, and water; sedimentary cycles include those of iron, calcium, phosphorus, sulfur, and other more-earthbound elements. ... In the hydrologic cycle, water is transferred between the land surface, the ocean, and the atmosphere.
The substance that is predominately absorbed in rain forests would be carbon dioxide, I believe. As many tropical trees are present and will uptake CO2 to synthesize glucose or sugar as a product of photosynthesis.
