Synthetic Biology02:55

Synthetic Biology

5.6K
Synthetic biology is an interdisciplinary science that involves using principles from disciplines such as engineering, molecular biology, cell biology, and systems biology. It involves remodeling existing organisms from nature or constructing completely new synthetic organisms for applications such as protein or enzyme production, bioremediation, value-added macromolecule production, and the addition of desirable traits to crops, to name a few.

The Replisome

DNA replication is carried out by a large complex of proteins that act in a coordinated matter to achieve high-fidelity DNA replication. Together this complex is known as the DNA replication machinery or the replisome.
The synthesis of the leading and lagging strands is a highly coordinated process. To explain this, the “Trombone model” was proposed by Bruce Alberts in 1980. The DNA loop formation starts when a primer is synthesized on the parent lagging strand. The loop grows with...

Naturalistic Observations

17.7K
If you want to understand how behavior occurs, one of the best ways to gain information is to simply observe the behavior in its natural context. However, people might change their behavior in unexpected ways if they know they are being observed. How do researchers obtain accurate information when people tend to hide their natural behavior? As an example, imagine that your professor asks everyone in your class to raise their hand if they always wash their hands after using the restroom. Chances...

DNA Replication02:40

DNA Replication

60.9K
DNA replication involves the separation of the two strands of the double helix, with each strand serving as a template from which the new complementary strand is copied.  After replication, each double-stranded DNA includes one parental or “old” strand and one “new” strand. This is known as semiconservative replication. The resulting DNA molecules have the same sequence and are divided equally into the two daughter cells.

Introduction to Biological Bases of Psychology

4.8K
Biopsychology serves as a vital bridge connecting the intricate domains of biology and psychology, shedding light on how biological systems influence psychological phenomena. This field scrutinizes the biological substrates of behavior and mental processes, emphasizing the nervous system along with the roles of neurotransmitters, hormones, and genetics. It also incorporates evolutionary perspectives to explain the adaptive nature of mental functions.
The nervous system, the cornerstone of...

Epistasis Analysis01:09

Epistasis Analysis

5.9K
Although Mendel chose seven unrelated traits in peas to study gene segregation, most traits involve multiple gene interactions that create a spectrum of phenotypes. When the interaction of various genes or alleles at different locations influences a phenotype, this is called epistasis. Epistasis often involves one gene masking or interfering with the expression of another (antagonistic epistasis). Epistasis often occurs when different genes are part of the same biochemical pathway. The...

  • Scientific Methodology
  • Research Integrity

Background:

  • Pseudoreplication is a controversial issue in experimental biology, leading to debates on its impact on study validity.
  • Concerns about pseudoreplication significantly influence the peer-review process for scientific publications.

Purpose of the Study:

  • To explore and clarify controversies surrounding pseudoreplication in scientific research.
  • To identify key issues related to pseudoreplication and propose resolutions.
  • To differentiate between non-independence of data and actual pseudoreplication.

Main Methods:

  • Literature review and conceptual analysis of pseudoreplication.
  • Examination of researcher disagreements and survey data on peer review impact.
  • Development of criteria for identifying and avoiding pseudoreplication.

Main Results:

  • Distinction established between non-independent data points and pseudoreplication.
  • Methodologies for minimizing and controlling risks of non-independence were identified.
  • Criteria for demonstrating the avoidance of pseudoreplication to satisfy scientific scrutiny were proposed.

Conclusions:

  • Avoiding pseudoreplication requires researchers to demonstrate control over data non-independence.
  • Clearer understanding and application of these principles can enhance research integrity and validity.
  • Resolving pseudoreplication controversies improves the peer-review process and scientific communication.
