In evolutionary bioinformatics, after understanding the range of available nucleotide and amino-acid substitution models and their underlying mathematical assumptions (including detailed treatment of the Jukes–Cantor and Kimura two-parameter models), the critical practical question arises: Which substitution model should be used for a given data set? Simply choosing the most complex model with the largest number […] The post Fitting Evolutionary Models to Sequence Data: Model Selection Using AIC, BIC and MEGA appeared first on RathBiotaClan.

Ribonucleic acid (RNA) is a polymeric molecule essential in various biological roles in coding, decoding, regulation, and expression of genes. Along with lipids, proteins, and carbohydrates, nucleic acids constitute one of the four major macromolecules essential for all known forms of life. Like DNA, RNA is assembled as a chain of nucleotides, but unlike DNA, […] The post RNA: Types, Structure and Role & Evolution of RNAs appeared first on RathBiotaClan.

College students who took notes by hand scored higher on questions that tested real understanding than students who typed notes on laptops, according to controlled experiments. A 2014 study in the journal Psychological Science examined how college students take lecture notes. It found that students who wrote notes by hand scored higher on conceptual test questions than […] The post Students who took notes by hand remembered more than students who typed, even when the typists wrote down more words. appeared first on RathBiotaClan.

Billions of possible changes in human DNA have been difficult to study one by one, but a new DeepMind atlas puts predictions for all of them in reach. Google DeepMind has released AlphaGenome Atlas, a free database that stores AI-generated predictions for the effects of all 9 billion possible single-letter mutations in the human genome. […] The post AlphaGenome Atlas Maps the Molecular Effects of 9 Billion Human DNA Mutations appeared first on RathBiotaClan.

Five baby orangutans were rescued on Tuesday 8 September 2026 from a casuarina forest in the Bichitrapur area of Bhograi block, Balasore district, Odisha, India. The rescue started the most thorough wildlife trafficking investigation in the region in more than one year. Officials suspect the animals came from outside India, mainly from the rainforests of […] The post Five baby orangutans found abandoned in Odisha forest; officials suspect international wildlife trafficking appeared first on RathBiotaClan.
