Answers:
a. We will see DNA fragments with 145-200 bps (only one band)
b. The DNA sequence linked to histones will be protected from the action of DNase I, thereby this enzyme only can cut linker DNA (i.e., 55 bp fragments). In consequence, it is expected to observe a single band with a length of approximately 145 to 200 base pairs
The bacterial genes are usually found in operons. Each operon comprises regulatory sequences of DNA that function as binding sites for regulatory proteins, which inhibit or encourage transcription. The regulatory proteins usually combine with small molecules that can make the protein inactive or active by altering its tendency to combine with DNA.
The four combinations of active or inactive regulatory proteins, which could be observed at any time in the cell are:
1. Active repressor, active activator,
2. Active repressor, inactive activator
3. Inactive repressor, active activator
4. Inactive repressor, inactive activator
Answer:
there is probably a high chance because spongesusie and most of her family are blue then maybe the little on will be blue
Explanation: don't know if this is the answer but at least i tried
Explanation:
Centimeters comprising cent, meaning 100 and the meter, a metric unit of measurement is th of a meter. Zettameters (Zm) and centimeters (cm) are both metric units; they measure length, thus
∵1 Zm= cm
∴ 6.42 Zm...
= * 6.42= cm
