TL;DR: As development of Artemia embryos approaches hatching, N 2 treatment appears to have a diminishing effect upon the control of guanosine nucleotide metabolism, and the rate of recovery of the nucleotide pools correlates well with the delay in the resumption of morphogenesis.

TL;DR: Analysis of the acid-soluble fraction during growth and development of the brine shrimp, Artemia salina, indicates diguanosine tetraphosphate (Gp 4 G) to be peculiar to the female and to be actively synthesized by the developing ovarian egg.

TL;DR: Quantitative extraction data along with 32Pi and adenosine-3H incorporation studies indicate that RNA synthesis during development of brine shrimp is most intense immediately after hatching, whereas very little RNA synthesis, if any, occurs beyond 36 hours development at 30°C.

TL;DR: A study of the protease(s) in undeveloped cysts of Artemia salina was initiated using 2,4,6-trinitrobenzenesulfonic acid to determine the release of amino groups upon protein hydrolysis, finding the versatility and sensitivity of this reagent made it possible to detect and characterize the proteolytic activity in small quantities of Cysts of the brine shrimp.

TL;DR: The absence of detectable 5-methylcytosine in DNA of developing Artemia supports the view that methylation status alone cannot account for regulation of transcription in protostomes, and that DNA methylation may be more common among deuterostomes.
