Question

Quizplus · Accepted Answer

The central dogma of molecular biology states that information flow in a cell is unidirectional, from DNA to RNA to protein. This means that DNA is transcribed into RNA, and RNA is translated into protein. The information cannot flow from protein back to DNA, as proteins cannot change the genetic information stored in DNA. Option A is incorrect because the flow of information in a cell is not reversible. Option B is incorrect because the flow of information is not from protein to DNA. Option D is incorrect because while the amino acid sequence of a protein can provide some information about the DNA sequence, it does not provide complete information about the gene, such as promoter regions and intron-exon boundaries. Option E is incorrect because the genetic code is degenerate, meaning that multiple codons can code for the same amino acid.
