Answer:
Explanation:
Proteins, such as RNA (ribonucleic acid) polymerase, were loaded into lane 2. TFIIB and TFIID are two forms of TFII. These proteins attach to the fragment of DNA. Furthermore, these proteins shield DNA from the DNase enzyme, which may trigger DNA to split. As a result of the above findings, we may conclude that the inserting proteins(RNA polymerase, TFIID and TR 8 proteins) cover the area between 500 and 800 bp (base pair) in the DNase I footprinting experiment.
As a consequence, the length duration is 300bp since the promoter area is about 500-800bp and is not digested by DNase after incubation of inserting proteins.

Answer:
9 Bitter and yellow spots
3 Bitter and no spots
3 Sweet and yellow spots
1 sweet and no spots
Explanation:
According to the given question, a homozygous plant with bitter fruit and yellow spots (BBSS) is crossed with a homozygous plant that has sweet fruit and no spots (bbss).
The F1 progeny would have bitter fruits with yellow spots. Crossing the F1 would obtain F2 progeny. As per the cross, the F2 progeny would have phenotypic ratio of 9 Bitter and yellow spots: 3 Bitter and no spots: 3 Sweet and yellow spots: 1 sweet and no spots.
