**Place the following sequence of steps in transcription in the correct order: mRNA separates from the DNA template
Free-floating mRNA nucleotides match up with their complementary nucleotides on the DNA strand
DNA helix unwinds and hydrogen bonds between nitrogen bases break at the gene location
mRNA moves into the cytoplasm and the DNA strands reform and rewind

the diploid number of chromosomes is sometimes represented by the symbol 2n. for the fruit fly, the diploid number is 8, which can be written as 2n = 8, where n represents twice the number of chromosomes in a sperm or egg cell.
