Signal Sequences and Sorting Receptors01:41

Signal Sequences and Sorting Receptors

8.9K
Signal sequences are short amino acid sequences that guide newly synthesized proteins to their proper location within the cell. Classical signal sequences are fifteen to sixty amino acids long and present at the N-terminus of a polypeptide chain. Each signal sequence has a conserved segment of basic residues towards their N terminus, a hydrophobic core, and a C-terminus rich in polar residues. The C-terminus also contains a signal cleavage site and features a -3 -1 sequence motif. The -3-1...

Per-Unit Sequence Models

135
An ideal Y-Y transformer, grounded through neutral impedances, displays per-unit sequence networks akin to those of a single-phase ideal transformer when subjected to balanced positive- or negative-sequence currents. These currents do not produce neutral currents, and their associated voltage drops.
Zero-sequence currents, which are identical in magnitude and phase, generate a neutral current, resulting in voltage drops across the neutral impedance and the low-voltage winding. If the...

Maxam-Gilbert Sequencing01:05

Maxam-Gilbert Sequencing

11.6K
In the same year as the discovery of the Sanger sequencing method, another group of scientists, Allan Maxam and Walter Gilbert, demonstrated their chemical-cleavage method for DNA sequencing. The Maxam-Gilbert method relies on using different chemicals that can cleave the DNA sequence at specific sites, the separation of resulting DNA fragments of variable size using electrophoresis, and deciphering the DNA sequence from the resulting gel bands.

Sanger Sequencing

760.1K
DNA sequencing is a fundamental technique that is routinely used in the biological sciences. This method can be applied to a range of questions at different scales - from the sequencing of a cloned DNA fragment or the study of a mutation in a gene up to whole-genome sequencing. However, despite the widespread use of sequencing today, it was not until 1977 that Fredrick Sanger and his collaborators developed the chain-termination method to decode DNA sequences. It relies on the separation of a...

Wald-Wolfowitz Runs Test I01:17

Wald-Wolfowitz Runs Test I

753
The Wald-Wolfowitz test, also known as the runs test, is a nonparametric statistical test used to assess the randomness of a sequence of two different types of elements (e.g., positive/negative values, successes/failures). It examines whether the order of the elements in a sequence is random or if there is a pattern or trend present. This nonparametric test applies to any ordered data despite the population and sample data distribution, even if a higher sample size is available.
The test works...

Next-generation Sequencing03:00

Next-generation Sequencing

93.4K
The first human genome sequencing project cost $2.7 billion and was declared complete in 2003, after 15 years of international cooperation and collaboration between several research teams and funding agencies. Today, with the advent of next-generation sequencing technologies, the cost and time of sequencing a human genome have dropped over 100 fold.
Next-Generation Sequencing Methods
Although all next-generation methods use different technologies, they all share a set of standard features....

Area of Science:

  • Neuroscience
  • Cognitive Neuroscience
  • Computational Neuroscience

Background:

  • The prefrontal cortex (PFC) is crucial for executive functions, including planning and memory.
  • Understanding how neural populations encode sequential information is vital for deciphering cognitive processes.

Purpose of the Study:

  • To investigate how the prefrontal cortex encodes self-ordered sequences.
  • To determine the impact of sequence consistency on neural population coding.

Main Methods:

  • Analysis of neural population activity in the prefrontal cortex.
  • Decoding of self-ordered sequences from neural data.
  • Assessment of information distribution and response variability.

Main Results:

  • Decoding accuracy was significantly better for consistent sequences compared to inconsistent ones.
  • Neural information was more distributed across the population when sequences were ordered consistently.
  • Population response patterns exhibited less variability under consistent ordering conditions.

Conclusions:

  • Consistent ordering of self-ordered sequences leads to more reliable and robust neural population codes in the prefrontal cortex.
  • These findings suggest that consistent sequence representation in the PFC may facilitate cognitive functions such as planning and memory.
