Answer:
The TATA box helps bind the <em>RNA polymerase</em> in the correct place.
Explanation:
The TATA box can be found before a gene. It is type of promoter sequence which allows for the process of transcription to begin.
The transcription factor proteins recognize the TATA sequence and bind to it. The RNA polymerase is positioned by the transcription factor proteins. The transcription factors form a binding site for the RNA polymerase which binds to the specific site and starts with the transcription process.
Cells, the basic unit of life, are derived from spontaneous generation.
Answer:
The males can only either be black or orange
Explanation:
There can be no male calico because for an offspring to be a calico the two codominant alleles must each be carried on the two X chromosomes and in the males, there is the presence of just one X chromosomes, thus they can either be black or be orange. For the females, the can only be black if they carry the black allele on both X chromosomes, the same goes for the orange.
