Abstract: Several hundred copies of L1-2_CR are present in the C. reinhardtii genome. They are ~98% identical to the consensus sequence and constitute ~0.5% of the genome. Since some elements are identical to each other, the genome harbors currently active L1-2_CR elements. The consensus is incomplete at the 5' end. The reconstructed portion encodes the 1439-aa L1-2_CRp protein (pos. 639-4955) composed of the endonuclease and reverse transcriptase domains.

They are inserted in different copies of the DNA-2-7_CR transposon at the same site (position 593 in the DNA-2-7_CR consensus sequence; usually the 593-601 region of DNA-2-7_CR is duplicated around the L1-2_CR inserts). The DNA-2-7_CR sequences that harbor the L1-2_CR elements are less identical to each other than the L1-2_CR sequences. Therefore, the L1-2_CR and DNA-2-7 elements cannot be different parts of the same composite transposon.
