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?
DNA is not a protein, and therefore does not have primary or secondary protein structure. Primary structure-the sequence of the nucleotides (amino acids in protein) Seco â¦ ndary structure-the interactions between bases (i.e. which parts of strands are bound to each other).1 person found this useful.rimary structure-the sequence of the nucleotides (amino acids in protein) Seco â¦ ndary structure-the interactions between bases (i.e. which parts of strands are bound to each other). 1 person found this useful.
