Group I introns are remarkable because: A: They are spliced by external RNA molecules without protein involvement. B: They are spliced by protein molecules in the absence of external RNA molecules. C: They are autocatalytic. D: They are only present in mitochondrial and chloroplast genomes.

MJPEG encoding compression technology is a dynamic image compression method based on the development of static image compression technology, which can compress continuous video streams to produce an image sequence. Its advantages are: ( ) A: Relatively simple to implement B: Encoding delay is small C: The picture can be spliced arbitrarily (the picture does not matter directly) D: Can flexibly adjust the compression frame rate and resolution
