Fint the incorrect statement about Multiple Sequence alignment (MSA).

#Section 7: Recombinant DNA technology and Other Tools in Biotechnology
  1. Sum of pair and Shannon’s entropy score are calculated to estimate optimal alignment in MSA.
  2. Shannon’s entropy in a MSA alignment < 1 are consider as a conserved region.
  3. Iterative alignment in comparison to Progressive alignment gives better and faster results.
  4. Example of Progressive alignment is Clustal and MUSCLE is an example of Iterative method.

Gel chromatography is used for hormone separation. A pilot-plant scale gel chromatography column packed with sephacryl resin is used to separate two hormones, A and B. The column is 5 cm in diameter and 30 cm in height: V, = 1.9x 10-4m3, Wr = 3x10-3m3 /kg dry sephacryl, ps =1.25 x 103 kg/m3 . The partition coefficients are kpA =0.38 and kpB= 0.15. If the eluting flow rate is 0.7 I/h, what is the retention time for each hormone?
