Summary Introduction
To write:
The site at which the restriction enzymes cuts the DNA.
Introduction:
Genome is defined as the complete genetic material that is present in an organism. It consists of the coding as well as the non-coding parts of DNA. The study of the genome is termed as genomics. Restriction enzymes are widely used enzymes in the field of genomics. This enzyme was discovered by three scientists named “Werner Arber, Hamilton Smith, and Daniel Nathans”.

The partial sequence of one strand of a double-stranded DNA molecule is
5'-GACGAAGTGCTGCAGAAAGTCCGCGTTATAGGCATGAATTCCTGAGG
-3'
EcoRI is a restriction enzyme that cleaves after G in the sequence 5'-GAATTC-3'. PstI is a restriction enzyme that cleaves after
A in the sequence 5'-CTGCAG-3'.
Write the sequence of both strands of the DNA fragment created when this DNA is cleaved with both EcoRI and PstI. The first
strand of your duplex DNA fragment should be derived from the given strand sequence.

For the DNA sequence shown, indicate the products of its cleavage with the following restriction endonucleases (AKA restriction enzymes):5′-ACAGCTGATTCGAATTCACGTT-3′3′-TGTCGACTAAGCTTAAGTGCAA-5′a) EcoRI (the recognition sequence and cleavage site is G↓AATTC);b) AluI (the recognition sequence and cleavage site is AG↓CT).
You plan to clone exon 11 of the HEXA gene (Section C) into the multiple cloning site (MCS) of the
plasmid vector pUC19 illustrated below. You PCR amplify only the 184 bp DNA region representing
exon 11 of HEXA from human DNA as a blunt-ended dsDNA fragment, and purify the amplicon.
Next you digest the vector pUC19 with the restriction enzyme (RE) Smal to obtain linear plasmid
DNA. You mix the PCR product and linear plasmid, add some DNA ligase enzyme in an appropriate
buffer, and incubate overnight at 16°C. The ligation mixture is used to transform competent E. coli
cells, which are subsequently streaked out onto agar plates containing ampicillin, X-gal and IPTG.
