Calohilara Pulchella
''Calohilara'' is a genus of flies in the family Empididae. It was originally considered a subgenus of ''Hilaria'', but raised to genus status due to morphological features such as "male eyes narrowly separated on the face with the enlarged anterior ommatidia, male and female wings with distinct dark markings and veins R2+3 strongly bent. The mitochondrial DNA of ''Calohilara tibetensis'' was sequenced in 2021. It consists of 15,354 base pairs, divided between 13 protein-coding genes, two ribosomal RNAs, and 22 transfer RNAs. It is similar to other mitochondrial DNA of the family Empididae, and the nucleotide composition also strongly uses adenine and thymine (which together make up 77.4% of the total).

Richard Karl Hjalmar Frey
Richard Karl Hjalmar Frey (1886–1965) was a Finnish entomologist. From 1919 to 1955, Richard Frey was head of the Finnish Museum of Natural History. He was primarily interested in Diptera and he described many new species in this Order. He studied exotic insects as well as those of Finland, especially those of Madeira and Cape Verde Cape Verde or Cabo Verde, officially the Republic of Cabo Verde, is an island country and archipelagic state of West Africa in the central Atlantic Ocean, consisting of ten volcanic islands with a combined land area of about . These islands .... Frey acquired by exchange or purchase many collections, notably the Georg Böttcher (1865–1915) collection of Philippine Diptera. When he retired, the University of Finland purchased his collection for the museum. Works Partial list *1941 Volume VI.Diptera.

Empididae
__NOTOC__ Empididae is a family of flies with over 3,000 described species occurring worldwide in all the biogeographic realms but the majority are found in the Holarctic. They are mainly predatory flies like most of their relatives in the Empidoidea, and exhibit a wide range of forms but are generally small to medium-sized, non-metallic and rather bristly. Common names for members of this family are dagger flies (referring to the sharp piercing mouthparts of some species) and balloon flies. The term "dance flies" is sometimes used for this family too, but the dance flies proper, formerly included herein, are now considered a separate family Hybotidae. Description Empididae are small to medium-sized flies, rarely large (1.0 to 15.0mm). The body is slender, or elongated and rarely thickset. The colour ranges from yellow to black, and they may be pollinose or lustrous, but never have a metallic gloss. The head is often small and rounded with relatively large eyes. The eyes of t ...

Hilaria
The Hilaria (; Latin "the cheerful ones", a term derived from the borrowed adjective "cheerful, merry") were ancient Roman religious festivals celebrated on the March equinox to honor Cybele. Origins The term seems originally to have been a name which was given to any day or season of rejoicing. The ''hilaria'' were, therefore, according to Maximus the Confessor either private or public. Among the former, he thinks it the day on which a person married, and on which a son was born; among the latter, those days of public rejoicings appointed by a new emperor. Such days were devoted to general rejoicings and public sacrifices, and no one was allowed to show any symptoms of grief or sorrow. The Romans also celebrated ''hilaria'' as a '' feria stativa'', on March 25, the seventh day before the Calends of April, in honor of Cybele, the mother of the gods; and it is probably to distinguish these ''hilaria'' from those mentioned above, that the '' Augustan History'' calls them Hi ...

Mitochondrial DNA
Mitochondrial DNA (mtDNA and mDNA) is the DNA located in the mitochondrion, mitochondria organelles in a eukaryotic cell that converts chemical energy from food into adenosine triphosphate (ATP). Mitochondrial DNA is a small portion of the DNA contained in a eukaryotic cell; most of the DNA is in the cell nucleus, and, in plants and algae, the DNA also is found in plastids, such as chloroplasts. Mitochondrial DNA is responsible for coding of 13 essential subunits of the complex oxidative phosphorylation (OXPHOS) system which has a role in cellular energy conversion. Human mitochondrial DNA was the first significant part of the human genome to be sequenced. This sequencing revealed that human mtDNA has 16,569 base pairs and encodes 13 proteins. As in other vertebrates, the human mitochondrial genetic code differs slightly from nuclear DNA. Since animal mtDNA evolves faster than nuclear genetic markers, it represents a mainstay of phylogenetics and evolutionary biology. It als ...

Protein-coding Genes
The human genome is a complete set of nucleic acid sequences for humans, encoded as the DNA within each of the 23 distinct chromosomes in the cell nucleus. A small DNA molecule is found within individual mitochondria. These are usually treated separately as the nuclear genome and the mitochondrial genome. Human genomes include both protein-coding DNA sequences and various types of DNA that does not encode proteins. The latter is a diverse category that includes DNA coding for non-translated RNA, such as that for ribosomal RNA, transfer RNA, ribozymes, small nuclear RNAs, and several types of regulatory RNAs. It also includes promoters and their associated gene-regulatory elements, DNA playing structural and replicatory roles, such as scaffolding regions, telomeres, centromeres, and origins of replication, plus large numbers of transposable elements, inserted viral DNA, non-functional pseudogenes and simple, highly repetitive sequences. Introns make up a large percentage ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ribosomal RNAs
Ribosomal ribonucleic acid (rRNA) is a type of non-coding RNA which is the primary component of ribosomes, essential to all cells. rRNA is a ribozyme which carries out protein synthesis in ribosomes. Ribosomal RNA is transcribed from ribosomal DNA (rDNA) and then bound to ribosomal proteins to form small and large ribosome subunits. rRNA is the physical and mechanical factor of the ribosome that forces transfer RNA (tRNA) and messenger RNA (mRNA) to process and translate the latter into proteins. Ribosomal RNA is the predominant form of RNA found in most cells; it makes up about 80% of cellular RNA despite never being translated into proteins itself. Ribosomes are composed of approximately 60% rRNA and 40% ribosomal proteins, though this ratio differs between prokaryotes and eukaryotes. Structure Although the primary structure of rRNA sequences can vary across organisms, base-pairing within these sequences commonly forms stem-loop configurations. The length and position of the ...
