Algorithms that compare two proteins or DNA sequences and produce an alignment of the best matching segments are widely used in molecular biology. These algorithms produce scores that when comparing random sequences of length n grow proportional to n or to log(n) depending on the algorithm ...
Sequence alignment: The lining up DNA sequences of different species in order to compare and find similarities between them. Homology: A similarity deriving from common ancestry. Answer and Explanation: Learn more about this topic: Comparative Genomics: Homology ...
In this bio-recipe we will analyze how significant is an alignment. This will be done by comparing the real alignment against alignments made out of shufflings of the same sequences.First we define the file name where we can find the SwissProt database and then load it. We also create Da...

After alignment of gene sequence of psoriasis with the gene sequence of lithospermum it is found that 63% score index is obtained. It is generally consider that score index from 50% to 70% is good for gene therapy of a particular disease.Pande V.V...

2C). Most of the silt-sized grains display A-axis alignment (Fig. 3A). Grain sizes in the SSFL range from 10 to 110 μm, which are clustered between 20 μm and 80 μm (Fig. 3B). Figure 2. Petrological characteristics of lacustrine shales in Chang 73 sub-member. (A) Well C30...
Based on a sequence alignment of heme-regulated proteins containing HRMs, we found that both IRP2 and Irr have His at the same position in the HRM (Cys-Pro-X-His), unlike other heme-regulated proteins, and positionally shifting of this histidine (Cys-Pro-X-X-His) in the HRM suppressed...
