How the Techniques of Molecular Biology Are Developed from Natural Systems
How the techniques of molecular biology are developed from natural systems Isobel Ronai [email protected] School of Life and Environmental Sciences, The University of Sydney, Sydney, NSW, Australia. Abstract A striking characteristic of the highly successful techniques in molecular biology is that they are derived from natural systems. RNA interference (RNAi), for example, utilises a mechanism that evolved in eukaryotes to destroy foreign nucleic acid. Other examples include restriction enzymes, the polymerase chain reaction, green fluorescent protein and CRISPR-Cas. I propose that biologists exploit natural molecular mechanisms for their effectors’ (protein or nucleic acid) activity and biological specificity (protein or nucleic acid can cause precise reactions). I also show that the developmental trajectory of novel techniques in molecular biology, such as RNAi, is four characteristic phases. The first phase is discovery of a biological phenomenon, typically as curiosity driven research. The second is identification of the mechanism’s trigger(s), the effector and biological specificity. The third is the application of the technique. The final phase is the maturation and refinement of the molecular biology technique. The development of new molecular biology techniques from nature is crucial for biological research. These techniques transform scientific knowledge and generate new knowledge. Keywords: mechanism; experiment; specificity; scientific practice; PCR; GFP. 1 Introduction Molecular biology is principally concerned with explaining the complex molecular phenomena underlying living processes by identifying the mechanisms that produce such processes (Tabery et al. 2015). In order to access the causal structure of molecular mechanisms it is generally necessary to manipulate the components of the mechanism and to observe the resulting effects with sophisticated molecular techniques. -

If true, this would provide a universal axis along which to organize protein 10 evolution and suggests that reconstructed ancestral proteins may be uniquely powerful tools 11 for protein engineering. Ancestral sequence reconstruction studies are one line of evidence 12 used to support this hypothesis. Previously, we performed such a study, investigating the 13 evolution of peptide binding specificity for the paralogs S100A5 and S100A6. -

A Cooperative Accomplishment of USDA Forest Service, Forestry Development Authority and Conservation International Steve Anderson and Dennis Gordon- USDA Forest Service May 29, 2005 to June 17, 2005 - 1 - USDA Forest Service, Forestry Development Authority and Conservation International Protected Area Development Management Plan Development Technical Assistance Report Steve Anderson and Dennis Gordon 17 June 2005 Goal Provide support to the FDA, CI and FFI to review and update the Sapo NP management plan, establish a management plan template, develop a program of activities for implementing the plan, and train FDA staff in developing future management plans. Summary Week 1 – Arrived in Monrovia on 29 May and met with Forestry Development Authority (FDA) staff and our two counterpart hosts, Theo Freeman and Morris Kamara, heads of the Wildlife Conservation and Protected Area Management and Protected Area Management respectively. We decided to concentrate on the immediate implementation needs for Sapo NP rather than a revision of existing management plan. The four of us, along with Tyler Christie of Conservation International (CI), worked in the CI office on the following topics: FDA Immediate -
Species Delimitation in Sea Anemones (Anthozoa: Actiniaria): from Traditional Taxonomy to Integrative Approaches
Preprints (www.preprints.org) | NOT PEER-REVIEWED | Posted: 10 November 2019 doi:10.20944/preprints201911.0118.v1 Paper presented at the 2nd Latin American Symposium of Cnidarians (XVIII COLACMAR) Species delimitation in sea anemones (Anthozoa: Actiniaria): From traditional taxonomy to integrative approaches Carlos A.

Brasil 2950, Valparaíso, Chile Abstract The present review provides an in-depth look into the complex topic of delimiting species in sea anemones. For most part of history this has been based on a small number of variable anatomic traits, many of which are used indistinctly across multiple taxonomic ranks. Early attempts to classify this group succeeded to comprise much of the diversity known to date, yet numerous taxa were mostly characterized by the lack of features rather than synapomorphies. Of the total number of species names within Actiniaria, about 77% are currently considered valid and more than half of them have several synonyms. Besides the nominal problem caused by large intraspecific variations and ambiguously described characters, genetic studies show that morphological convergences are also widespread among molecular phylogenies. -
Tambourine Dove Is Always More Readily Heard Than Seen
520 Columbidae: pigeons and doves of undergrowth. Dowsett-Lemaire (1983b) found that in Afromontane forest in Malawi, the minimum-sized terri- tory for a breeding pair was 2.3 ha. Movements: It is considered to be sedentary. However, Rowan (1983) referred to a ringing study at Mtunzini (2831DD) in which two- to fourfold increases in capture rates were recorded July–August, in each of four years. The models show clear peaks in reporting rates, but at differ- ent times of year. If one assumes that long-distance migra- tion does not occur, these differences probably represent differences in breeding season with concomitant differ- ences in the timing of vocalizations associated with breed- ing, and post-breeding dispersal; the Tambourine Dove is always more readily heard than seen. Breeding: Rowan (1983) provided data for KwaZulu- Natal and Zimbabwe where nests with eggs may be found September–May, peaking October–November. The few atlas records, and the peaks in the occurrence models (see above) for Zones 5 and 6, appear to agree with this, but earlier peaks in reporting rates in Zones 4, 7 and 8 suggest that breeding is earlier in the south. Interspecific relationships: It is sometimes seen to- gether with Cinnamon Doves Aplopelia larvata when both are attracted by the same seed falls on the forest floor. It also overlaps in some areas with the Greenspotted Dove and, in eastern Zimbabwe, with the Bluespotted Dove T. afer. Rowan (1983) reported an obscure reference to a hybrid between Bluespotted and Tambourine Doves, but the hybrid was believed to be infertile and the mating presumably occurred in captivity. -

Introduction: the Powers of Association
Copyrighted Material CHAPTER ONE Introduction: The Powers of Association In the summer of 2000, as the rainy season started, I made my way to the poor Dakar suburb of Th iaroye to meet a family with multiple cases of sickle cell anemia. Th ere were no paved sidewalks and my shoes sank in the mud when I jumped off the rusty minibus in a line of other hurried passengers. Stray sewer water bubbled from an opening in the street, creating small puddles of grey that were now being abluted by the downpour. Mr. Seck, the man I had come to see, had his niece keep watch for me, “the American from the hospital.” She surveyed me like sport as I divided my attention between the faulty gutters and locating the house. When we entered the compound, Seck welcomed me with a hard handshake. Th e whole family joined around, every one extending an arm, to introduce themselves with the familiarity and cheer an American usually reserves for a loved one. Doctors in town had recently diagnosed two of Seck’s children, ages eight and twelve, with HbSC sickle cell anemia, a less serious, heterozygous form of the more common homozygous HbSS disease. Both forms of the illness pro duce the hallmark symptom of this hemoglobin disorder: the vascular pain of arterial vessels clogged with sticky, damaged red blood cells, commonly called “the sickle cell crisis.” Th e children were prescribed folic acid for fi ft een days a month and Doliprane, the local name of acetaminophen, for pain when needed.
