Depending on the species (species of plant, algae etc) plastids may take up a variety of shapes ranging from discoid, spherical, dumbbell-shaped or lens-shaped among a few others. *Under stressful conditions, mitochondria have also been observed in plastids (by intrusion). This has been shown...
Precise genome duplication and accurate cellular division are crucial for the continuation of a cell's life. In all three biological domains, bacteria, archaea, and eukaryotes, initiator proteins, utilizing ATP, engage with replication origins, effectively controlling replisome development and coordinating...
which exhibited the BET surface area as high as 3002 m2 g-121. Being a unique member ofaPOPs, the first kind of PIMs was reported by McKeown and Budd in 200416. The porous character of these polymers is originated from the high rigid structures and the contorted shapes in the linea...
Although the use of bacteria in antitumoral therapy has been largely restricted, the use of therapeutic viruses is increasing. Virus-based therapy was introduced in the 1990s with the use of adenovirus, but only in recent years has it been used in practice in the clinic. Oncologic viruses190ha...
Cryo-EM analysis of complement C3 reveals a reversible major opening of the macroglobulin ring Article23 January 2025 Introduction The complement system comprises >30 soluble and membrane-associated protein factors that survey the blood and interstitial fluids for the presence of viruses, bacteria, eukar...
research group was part of the project. “We made the armour with honeycombs of different sizes, shapes and materials. The beauty of this result is that it is a generic concept that fits for many different materials, giving us the flexibility to design a wide range of durable waterproof...
26 The upper forelimbs of humans and bats have fairly similar skeletal structures, whereas the corresponding bones in whales have very different shapes and proportions. However, genetic data suggest that all three kinds of organisms diverged from a common ancestor at about the same time. Which o...
