The nucleotide sequences of twoLupinus luteusasparagine tRNAs

Nucleotide sequences of two glutamine tRNAs from HeLa cells.

We reported previously that 4.5S RNAj, is associated with poly A RNAs of rodent cells (1). However, this molecule was not found in human, monkey, cat, mink, rabbit or chicken cells ^1) . In HeLa cells, several 4S RNAs are released from the poly A RNA fraction (1) . We determined the nudeotide sequence of one of the most abundant 4S RNA species in this fraction. Nudeotide sequence analysis was p...

Halobacterium volcanii tRNAs. Identification of 41 tRNAs covering all amino acids, and the sequences of 33 class I tRNAs.

Transfer RNAs of Halobacterium volcanii, an archaebacterium, were separated by two-dimensional gel electrophoresis and sequenced by a combination of methods. A total of 41 tRNAs, at least one for each amino acid, were identified. These are five tRNAs for Leu, four for Gly, three each for Ala, Arg, Pro, and Ser, two each for Glu, Ile, Lys, Met (initiator and noninitiator), Thr, and Val, and one ...

Statistical analysis of nucleotide sequences.

In order to scan nucleic acid databases for potentially relevant but as yet unknown signals, we have developed an improved statistical model for pattern analysis of nucleic acid sequences by modifying previous methods based on Markov chains. We demonstrate the importance of selecting the appropriate parameters in order for the method to function at all. The model allows the simultaneous analysi...

The nucleotide sequence and characterization of four chloroplast tRNAs from the alga codium fragile.

The nucleotide sequences of four chloroplast tRNAs (methionine elongator, lysine, glycine, and arginine) from the siphonaceous green alga Codium fragile have been determined. These tRNAs have an unusually high A-U content compared to other chloroplast tRNAs and show varied, but in general only limited, sequence homology to the corresponding tRNAs of other chloroplasts. The locations of the gene...
