Modern cells are complex chemical entities with cytoskeletons, finely regulated internal and external molecules, and genetic ...

The clean_sequence function is a tool that takes a DNA or RNA sequence as input and removes any characters that are not A, C, G, T (for DNA) or A, C, G, U (for RNA). It returns a character string ...

Given the importance of recursion in modern linguistics, there ought to be much to commend in Watumull et al.'s (2014) attempt to clarify what recursion is (or ought to be); I have trudged this very ...

Abstract: Aperiodic autocorrelation is an important indicator of performance of sequences used in communications, remote sensing, and scientific instrumentation. Knowing a sequence’s autocorrelation ...

A research team has revealed the molecular steps that led to the emergence of this plant-specific vacuolar transport system. Their work shows that the acquisition of this pathway was driven by the ...

To understand recursion, you must first understand recursion. You may think of recursion as a programming structure where a function calls itself. We call such a function a recursive function. Many ...

Over more than three billion years, natural evolution has intricately shaped the proteins we see today. Through countless random mutations and selective pressures, nature has crafted these proteins, ...

Abstract: We present a general algorithm for generating arbitrary standard complementary pairs of sequences (including binary, polyphase, M-PSK and QAM) of length 2 N using Boolean functions. The ...

Scientists have discovered that a protein responsible for the synthesis of a key plant material evolved much earlier than suspected. This new research explored the origin and evolution of the ...
