Radio Stars. Quasars are the brightest and most distant objects in the known universe. In the early 1960's, quasars were referred to as radio stars because they were discovered to be a strong source of radio waves. In fact, the term quasar comes from the words, quasi-stellar radio source.
The following DNA sequence occurs in the nontemplate strand of a structural gene in bacterium (the promoter sequence is located to the left but is not shown): 5 -GAATGTCAGAACTGCCATGCTTCATATGAATAGACCTCTAG-3 What is the ribonucleotide sequence of mRNA molecule that is transcribed from this piece of DNA?
Has a nucleotide sequence exactly complementary to the strand of DNA used as a template (uracil bonded with A, rather than T-A) â¦ Elongated one nucleotide at a time by RNA polymerase â¦ RNA strand is immediately re;leased from the DNA strand â This means that many RNA copies of the same gene can be made in a short time.
