The size of genomic DNA from E.Coli is about 4,500 kb which is beyond the limit of the gel or the DNA ladder used. Appearance of E.Coli DNA is shown in Figure 1b.

In our experiment – There are three fragments of DNA which shows that the inserted PCR product must have one ECoRI site. The ECoRI site in the PCR product is placed almost in the middle breaking it into two fragments, viz. 600 bp and 800 bp (Fig. 6).
Interpretation - It appears that the insert has two restriction sites for NCoI (Fig 7). But position of the sites would result in a DNA fragment smaller than 1.5 kb (the total size of the insert), the size discrepancy is difficult to explain.
Interpretation – This result is totally unexpected! The bands corresponding to both the restriction enzymes, i.e. at 1.0 kb, 2.5 kb, 3.0 kb are there but in addition there are three other intermediate size DNA fragments. The bands appear to be intermediates produced due to impartial digestion of the recombinant by the two restriction enzymes.
Reason – Concentration of the enzymes was less, time of incubation is less than optimum or incubation conditions were inadequate. Sufficient time should be given for the restriction enzymes to act on all the sites.
ii. NcoI digestion (Lane 4) – the restriction sites appear to be different than mine (Fig 4a). The NcoI sites appear to be closer in the 16S rDNA extracted by this student and give rise to a DNA fragment of 600 bp.

Experiment to determine the presence of a single nucleotide polymorphism in a gene
The SNP genomic distribution has no homogeneity. It always occurs in those regions that are non-coding. It has minimum occurrence in the regions that are coded. This is a case where the natural selection acts and fixes the SNP allele with favorable adaptation

Per3 Gene and Diurnal Preference

The studies have found that a biallelic VNTR (variable number tandem repeat) polymorphism is present in the human PER3 gene at the chromosome 1p36.23, and it contains two alleles with 4 or 5 tandem repeats of 54 bp.This VNTR was evaluated as the important genetic factor for the chronotypes as it is associated with the diurnal preference.

Design and Technology
Design for assembly can be defined as the process of systematic analyses aimed at simplifying the structure of the product as well as reducing the products assembly cost. The assembly quality of the product is associated with the number of parts. The DFA technique can enable the rating of the assimilability by the designers quantitatively.
