Design Example: Setting a Curve Using Design Data

234
Designing and plotting a curve using field data requires precise calculations and execution. A horizontal curve with a radius of 200 meters and an intersection angle of 20 degrees is established using the method of perpendicular offsets from the long chord. The long chord, which spans between the curve's endpoints, is calculated to be 69.46 meters in length. To maintain accuracy in plotting, intervals of 3 meters are selected along the chord.The engineer determines the offset distances for each...

Mutations

44.5K
Mutations are changes in the sequence of DNA. These changes can occur spontaneously or they can be induced by exposure to environmental factors. Mutations can be characterized in a number of different ways: whether and how they alter the amino acid sequence of the protein, whether they occur over a small or large area of DNA, and whether they occur in somatic cells or germline cells.

While point mutations are changes in a single nucleotide in...

What is Variation?01:14

What is Variation?

18.4K
Apart from the measures of central tendency, distribution, outliers, and the changing characteristics of data with time, an important characteristic of any data set is its variation or spread. In some data sets, the data values are concentrated closely near the mean; in others, the data values are more widely spread out from the mean.
The range, standard deviation, standard error, and variance are the different measures of variation.
Range: The range is the difference between its maximum and...

Mutation, Gene Flow, and Genetic Drift01:09

Mutation, Gene Flow, and Genetic Drift

64.2K
In a population that is not at Hardy-Weinberg equilibrium, the frequency of alleles changes over time. Therefore, any deviations from the five conditions of Hardy-Weinberg equilibrium can alter the genetic variation of a given population. Conditions that change the genetic variability of a population include mutations, natural selection, non-random mating, gene flow, and genetic drift (small population size).

Viral Mutations00:36

Viral Mutations

39.9K
A mutation is a change in the sequence of bases of DNA or RNA in a genome. Some mutations occur during replication of the genome due to errors made by the polymerase enzymes that replicate DNA or RNA. Unlike DNA polymerase, RNA polymerase is prone to errors because it is not capable of “proofreading” its work. Viruses with RNA-based genomes, like HIV, therefore accrue mutations faster than viruses with DNA-based genomes. Because mutation and recombination provide the raw material...

Area of Science:

  • Genomics
  • Molecular Biology
  • Biochemistry

Background:

  • Genomic variation data at the nucleotide level is abundant, but understanding its functional consequences, particularly amino acid variations, remains a challenge.
  • Amino acid variations can lead to phenotypic differences or diseases by affecting cellular processes, which are driven by molecular interactions.
  • Connecting sequence variation to phenotype requires understanding how these variations impact molecular interactions.

Purpose of the Study:

  • To present a comprehensive, open-access resource detailing the effects of small sequence changes on physical protein interactions.
  • To provide a descriptive analysis of this curated dataset, facilitating research into the mechanistic basis of variation.

Main Methods:

  • Curated data over 14 years by IMEx database curators.
  • Inclusion of 28,000 annotations on the impact of sequence variations on protein interactions.
  • Data compilation and descriptive analysis.

Main Results:

  • A resource with 28,000 annotations on sequence variation effects on protein interactions is now available.
  • The resource details how small sequence changes influence physical protein interactions.
  • The dataset is publicly accessible and continuously updated.

Conclusions:

  • This resource provides a valuable tool for connecting mechanistic characterization of nonsynonymous variation to phenotype.
  • Understanding the impact of genetic variation on protein interactions is key to deciphering cellular processes and disease mechanisms.
  • The ongoing curation and monthly updates ensure the resource remains a dynamic and relevant asset for the scientific community.
