The organization of the chicken lysozyme gene and its neighboring sequences was examined by a comparison of the restriction map of the lysozyme structural gene with the map of the lysozyme gene in genomic DNA. Chicken DNA was cleaved with restriction endonucleases and the DNA fragments were separated by agarose gel electrophoresis. After transfer of the fragments onto nitrocellulose filters, those fragments that contain lysozyme mRNA sequences were detected by hybridization of the filters to labeled probes generated from pls-1, a recombinant plasmid carrying the lysozyme structural gene. This analysis revealed the presence of at least three intervening sequences, two of which interrupt the protein coding region and one of which is located in the 3' untranslated region. When oviduct DNA and sperm DNA were compared, no difference was observed in the size and number of restriction fragments that contain either lysozyme or ovalbumin structural gene sequences.

D008297 Male Males
D009113 Muramidase A basic enzyme that is present in saliva, tears, egg white, and many animal fluids. It functions as an antibacterial agent. The enzyme catalyzes the hydrolysis of 1,4-beta-linkages between N-acetylmuramic acid and N-acetyl-D-glucosamine residues in peptidoglycan and between N-acetyl-D-glucosamine residues in chitodextrin.

D009694 Nucleic Acid Precursors Use for nucleic acid precursors in general or for which there is no specific heading. Acid Precursors, Nucleic,Precursors, Nucleic Acid
D010047 Ovalbumin An albumin obtained from the white of eggs. It is a member of the serpin superfamily. Serpin B14
D010057 Oviducts Ducts that serve exclusively for the passage of eggs from the ovaries to the exterior of the body. In non-mammals, they are termed oviducts. In mammals, they are highly specialized and known as FALLOPIAN TUBES. Oviduct

D004262 DNA Restriction Enzymes Enzymes that are part of the restriction-modification systems. They catalyze the endonucleolytic cleavage of DNA sequences which lack the species-specific methylation pattern in the host cell's DNA. Cleavage yields random or specific double-stranded fragments with terminal 5'-phosphates. The function of restriction enzymes is to destroy any foreign DNA that invades the host cell. Most have been studied in bacterial systems, but a few have been found in eukaryotic organisms. They are also used as tools for the systematic dissection and mapping of chromosomes, in the determination of base sequences of DNAs, and have made it possible to splice and recombine genes from one organism into the genome of another.

D000818 Animals Unicellular or multicellular, heterotrophic organisms, that have sensation and the power of voluntary movement. Under the older five kingdom paradigm, Animalia was one of the kingdoms. Under the modern three domain model, Animalia represents one of the many groups in the domain EUKARYOTA.
