"internal mismatch" is correct and usable in written English.
You can use it when referring to discrepancies or inconsistencies between the components or expectations of a particular system. For example, "The misalignment of the internal systems resulted in a serious internal mismatch."
Internal stress plasticity occurs when a small external stress biases internal mismatch strains produced by, e.g., phase transformation or thermal expansion mismatch.
Consequently, the observed densification enhancement during thermal cycling is confirmed to be due to internal stress plasticity, which is produced by internal mismatch stresses between adjacent zinc grains with anisotropic thermal expansion.
The miR-122 stem contains a bulge, so we designed one short hairpin, FLuc-ShM, with an internal mismatch in order to mimic the miR-122 structure.
All four oligos in this set will have mismatches at their terminal (1st and 25th) positions, and three of four have an internal mismatch at the central (13th) position.
As expected, allowing for 1 internal mismatch increases the overall proportion of palindromic dyad sites matched compared to no mismatches allowed, but only a negligible increase is observed when considering 2 mismatches.
Mal d 1 and Cor a 1 variants were generated by PCR amplification of mutated fragments of Mal d 1.0108 (and17551) and Cor a 1.0401 (AF136945) using internal mismatch primers (Table S1) as described in the article's online Supporting Information.
The homologous sequence of TrpC3-shRNA#2 in Homo sapiens TrpC3 is 5'-GGCGGCGCACTGCCAGAAA-3', where the underlined bases represent internal mismatches compared to the target sequence in rat TrpC3.
Number of internal mismatches within the fragment.
Internal mismatches destabilise the duplex more significantly than terminal mismatches [ 24, 28].
Terminal mismatches in very short duplexes have long been known to have less effect than internal mismatches [ 29].
Briefly, a preannealed mismatched duplex was made by mixing 200 mM P-labelled 29-mer oligonucleotide with its complementary oligonucleotide containing four internal mismatches (mm29c) in water.
