Q: What is dna transcribed into after being replicated? Read this paragraph and choose the correct option from the provided answers: The three general transfers are believed to occur normally in most cells. These describe the normal flow of biological information. DNA is replicated, DNA is transcribed into RNA, and RNA is translated into protein. The three special transfers are known to occur under special conditions, such as with some viruses. The three unknown transfers are not believed to occur. Choices: - protein - diploid chromosomes - gene - rna A:

Q: Enzymes in cellular reactions work to do what to the reaction? Read this paragraph and choose the correct option from the provided answers: Enzymes are extremely efficient in speeding up reactions. They can catalyze up to several million reactions per second. As a result, the difference in rates of biochemical reactions with and without enzymes may be enormous. A typical biochemical reaction might take hours or even days to occur under normal cellular conditions without an enzyme, but less than a second with an enzyme. Choices: - increase yield - decrease heat - slow it down - speed it up A:
(A).
speed it up
