Which statement is not true about the TATA box?

#SCPH28 | Zoology

  1. The TBP portion of the general transcription factor TFIID binds to the TATA box forming a molecular clamp.

  2. It is located about 19-27 bp upstream from the transcription start site of class II genes.

  3. Its sequence is highly conserved among all species.

  4. This region of DNA is more easily unwound to an open complex than other general sections of DNA.

#SCPH01 Biochemistry

You are studying regulation of the yeast enzyme glutamine synthetase (GS), which is encoded by the GLN1 gene. You have isolated two mutants, designated gln2– and gln3–, that give decreased GS activity. Mating of either gln2– or gln3– haploids to wild type produces heterozygous diploids that show normal amounts of GS expression. When you cross either a gln2– or gln3– haploid to a gln1– strain the resulting diploids show normal expression of GS.              
From these experiments,  Classify  the  gln2– and gln3– mutations in terms of their basic genetic properties explaining the rationale behind your conclusions. Based on these properties make a proposal for the types of regulatory functions affected by the gln2– and gln3– mutations.
