Sentence examples for different types of nucleotide from inspiring English sources

To determine whether different types of nucleotide mismatches differ significantly across mismatch positions, the mean level of log2 PM/MM) was calculated and graphed for different categories according to mismatch type and mismatch position classification.

The structure they wished to suggest gave birth to an icon: the double helix.Building on the work of many others, they described how the two spiral chains which make up DNA are coiled around a single axis, and how the two strands unite through the precise pairing of four different types of nucleotide bases adenine, cytosine, guanine and thymine.

For example each presents different types of nucleotide composition skews (as detected with the Zcurve method [61]) (Figure 2A).

To understand the process of newly arising variants we analyzed the different types of nucleotide changes that occurred.

These frequencies varied greatly among the different types of nucleotide changes, indicating the non-randomness of the nucleotide changes in the chimpanzee genome.

Furthermore, we did identify a range of all 12 different types of nucleotide changes that can occur (Additional File 5) with C to T changes being the most common (~25%).

What is more interesting is that H. volcanii uses only 16 different types of modified nucleotides at 18 positions in the 46 mature tRNA isoacceptors, while both E. coli and S. cerevisiae use at least 28 different types of modified nucleotides at 20 and 35 different positions respectively [ 4, 71].

In E. coli there are 16 different types of modified nucleotides within 35 positions of the 16+23S rRNAs and in S. cerevisiae 18+23+5S rRNAs contain at least 8 different modified nucleotides located at more than 100 positions [ 12, 13].

Using a machine learning method that is designed to work on data structures that are as flexible as graphs allows us to model the structure of RNA in a natural way, with vertices representing nucleotides and edges representing the different types of bonds between nucleotides, i.e. backbone phosphate bonds and base-pairing bonds.

Among the different types of SSRs, di-nucleotide repeats were the majority, accounting for 55.49% in 'Ventura' and 54.84% in 'Jinnan Shiqin', while other types (tetra-, penta- and hexa-nucleotide repeats) exhibited a frequency of less than 2%.

To explain the low entropy, we examined different types of biases in the nucleotide composition.
