Once per every 4^n the restriction enzymes cuts the random DNA.
n - It is the number of bases that the restriction enzyme can recognize.
a) SmaI - Recognise the sequence CCC-GGG that means it has got 6 base recognition site that means they will cut the DNA sequence at a frequency of once per every 4^6, that means 4096 bases.
So the number of fragments produced = 300000 / 4096 = 73.2 = approx. 73 fragments
b) HaeIII - Recognise the sequence GG-CC that shows that it got 4 base recognization site so it will cut the DNA sequence at a frequency of once per every 4 ^4 that is 256 bases.
Thus the number of fragments produced = 300000 / 256 = 1171.8 = approx . 1172 fragments
c) NotI - Recognise the sequence GC-GGCCGC that shows that it has got an 8 base recognition site so it will cut the DNA sequence at a frequency of once per every 4^8 that is 65536
Thus the number of fragments produced = 300000 / 65536 = 4.577 = approx. 5 fragments

Identify two restriction
endonucleases that could be used to make sticky ends near the
5’ end of this DNA sequence (upper strand) so that
it could be incorporated into a new plasmid. You have a short list
of them in Table 9-2, and the specific, short sequences of bases
that other enzymes cut at are easily obtained from web resources.

please answer question numbe 2.
Restriction endonucleases are bacterial enzymes that recognize, bind, and cut DNA strands at specific recognition sequences. They evolved to protect bacteria from bacterial viruses and are very useful for a wide variety of molecular biology applications. Some of the more common ones include EcoRI which recognizes the 6 bp sequence 5 'GAATTC 3' and cleaves the phosphodiester backbone after the G. Hind III_(AAGCTT), BamHI (G|GATCC), Pstl (CTGCAG), Not!

Chromosomal and plasmid DNA can be cut into manageable pieces by
restriction enzymes. Using agarose gel electrophoresis, the DNA
fragments can be separated on a gel, based on their lengths. In
order to see the fragments, a stain is typically added to the gel.
The size of each fragment can be determined by comparing each one
to a DNA molecular weight marker of known size.
