1) The nucleotide sequence of the attenuator region in the leader of the trp mRNA - a) Contains features of a transcription termination site Depurination - the loss of a purine base from a nucleotide Deamination - the removal of an amino group from an organism, particularly from an amino acid attenuator region - region of RNA sequence that forms an alternate secondary structures that govern the level of transcription of attenuated operons. Transcription factors and other regulatory p...

Overall organizational structure of the human chromosome - correct answer normally contain a single, immensely long DNA double helix; to avoid tangling and to manage the long chain efficiently they are complexed with various proteins and sometimes noncoding RNAs to form chromatin that undergoes different levels of coiling and compaction Chromatin - correct answer the structure of DNA complexes with pro...
