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?
is the non-coding strand complementary to the coding strand in double-stranded DNA. The antisense strand serves as the template for messenger RNA (mRNA) synthesis. is the non-coding strand complementary to a coding sequence of mRNA, a molecule involved in translating genetic instructions into proteins. Antisense RNA hybridizes with and inactivates mRNA.
