In E. coli, deleting the ribosome binding site and region 1 of the trp attenuator and leaving the remainder of the attenuator intact has which of the following effects?

#SCPH01 Biochemistry
  1. The attenuator structure will not form, and the structural genes will be transcribed.

  2. The attenuator structure will always form, and transcription will terminate.

  3. The frequency of attenuation will still be controlled by the concentration of trp-tRNAtrp.

  4. Translation of the structural genes will not occur.

During early cleavage stages in drosophila, nuclei divide through 13 cycles in the absence of any cytoplasmic cleavage. This division creates an embryo of many nuclei contained within one shared cytoplasm surrounded by one common plasma membrane, this process is called as-
