The researchers detected this SMN long
noncoding RNA, or lnc - RNA (pronounced «link RNA») for
short, in human embryonic kidney cells, brain cell samples and neurons derived from the stem cells of healthy people and those with spinal muscular atrophy type I and II.
Noncoding DNA includes stretches called enhancers,
short sequences that help control a target gene.
To their surprise and dismay, the genome turned out to contain long stretches of
noncoding and repetitive DNA, which made it difficult to piece together the
short reads produced by the sequencing machine.
The differences between coding versus
noncoding trees were not solely due to
shorter sequence length of the coding data, because the full coding data set (13.3 million bp for c123) produced a tree with fully supported (100 % BS) relationships that were incongruent with those fully supported in the intron (19.3 million bp), TENT (37.4 million bp without the third codon position), and WGT (322.1 million bp)(Figs. 2 and 5B, and table S3).
Spliceosomes, made from proteins and
short,
noncoding RNA fragments, carry out splicing via catalysis, which in biological processes is usually attributed to protein - based enzymes.
