Polytene Chromosomes02:04

Polytene Chromosomes

Polytene chromosomes are giant interphase chromosomes with several DNA strands placed side by side. They were discovered in the year 1881 by Balbiani in salivary glands, intestine, muscles, malpighian tubules, and hypoderm of larvae Chironomus plumosus. Hence, these are also called "Salivary gland chromosomes." These are found in insects of the order Diptera and Collembola; in certain organs of mammals; and synergids, antipodes of flowering plants. Polytene chromosomes are also regularly...

Additional Subnuclear Structures02:10

Additional Subnuclear Structures

The eukaryotic nucleus is a double membrane-bound organelle that contains nearly all of the cell’s genetic material in the form of chromosomes. It is rightly called the “brain” of the cell as it shoulders the responsibility of responding to various physiological processes, stress, altered metabolic conditions, and other cellular signals. 
The nucleus contains many membrane-less subnuclear organelles or nuclear bodies, such as nucleoli, Cajal bodies, speckles, paraspeckles, etc. These nuclear...
Gene Families01:57

Gene Families

Gene families consist of groups of genes proposed to have originated from a common ancestor. Typically these arise through events in which a gene or genes are mistakenly duplicated during cell division. Unlike their parent genes (which are subject to selection pressure to maintain function), these gene copies do not need to preserve their sequences and may evolve at a relatively faster rate.
Occasionally these regions can be adapted to take on new roles within the organism, becoming novel genes...

Chromatin Structure and RNA Splicing02:41

Chromatin Structure and RNA Splicing

In eukaryotic cells, nascent mRNA transcripts need to undergo many post-transcriptional modifications to reach the cell cytoplasm and translate into functional proteins. For a long time, transcription and pre-mRNA processing were considered two independent events that occur sequentially in the cell. However, it has now been well established that transcription and pre-mRNA processing are two simultaneous processes that are precisely regulated inside the cell.
The chromatin structure, especially...

Area of Science:

  • Linguistics
  • Computational Linguistics
  • Psycholinguistics

Background:

  • Child language corpora are crucial for understanding language acquisition.
  • Linguistic annotation of these corpora aids in analyzing grammatical development and usage.
  • The CHILDES database is a primary resource for child language research.

Purpose of the Study:

  • To annotate the English CHILDES database with grammatical relations using labeled dependency structures.
  • To develop a data-driven parser for accurate grammatical relation annotation.
  • To make annotated data and parser tools freely available to the research community.

Main Methods:

  • Manual curation of gold-standard grammatical relation annotations for a subset of CHILDES data.
  • Development of a data-driven parser trained on manually annotated data.
  • Automatic annotation of the remaining English CHILDES data using the developed parser.
  • Extension of the parser to support Spanish and other languages.

Main Results:

  • Creation of a corpus with over 18,800 utterances (approx. 65,000 words) of gold-standard annotations.
  • Development of a highly accurate data-driven parser for English CHILDES data.
  • Successful automatic annotation of the entire English CHILDES section.
  • Parser extended for Spanish, with ongoing multilingual support.

Conclusions:

  • The developed parser significantly enhances the annotation of child language corpora.
  • Freely available annotated data and tools facilitate research in child language acquisition and psycholinguistics.
  • The project paves the way for large-scale, cross-linguistic analysis of child language development.
