Multi-species Conserved Sequences02:51

Multi-species Conserved Sequences

4.6K
Next-generation sequencing technologies have created large genomic databases of a variety of animals and plants. Ever since the human genome project was completed, scientists studied the genome of primates, mammals, and other phylogenetically distant living beings. Such large-scale  studies have provided new insights into the evolutionary relationship between organisms.
Although the genome of each species varies greatly from each other, a few sequences are highly conserved. Such conserved...

lncRNA - Long Non-coding RNAs

9.6K
In humans, more than 80% of the genome gets transcribed. However, only around 2% of the genome codes for proteins. The remaining part produces non-coding RNAs which includes ribosomal RNAs, transfer RNAs, telomerase RNAs, and regulatory RNAs, among other types. A large number of regulatory non-coding RNAs have been classified into two groups depending upon their length – small non-coding RNAs, such as microRNA, which are less than 200 nucleotides in length, and long non-coding RNA...

Conservation of Protein Domains Over Different Proteins

13.9K
Protein domains are small structurally independent units that are part of a single amino acid chain.  Although these domains are often structurally independent, they may rely on synergistic effects to perform their functions as part of a larger protein. Protein domains may be conserved within the same organism, as well as across different organisms.
A limited set of protein domains often duplicate and recombine during evolution. These domains can be organized in different combinations to...

Types of RNA01:20

Types of RNA

8.7K
Three main types of RNA are involved in protein synthesis: messenger RNA (mRNA), transfer RNA (tRNA), and ribosomal RNA (rRNA). These RNAs perform diverse functions and can be broadly classified as protein-coding or non-coding RNA. Non-coding RNAs play important roles in regulating gene expression in response to developmental and environmental changes. Non-coding RNAs in prokaryotes can be manipulated to develop more effective antibacterial drugs for human or animal use.

Area of Science:

  • Molecular Biology
  • Genetics
  • Cell Biology

Background:

  • Chromosome segregation ensures accurate genetic material distribution.
  • Kinetochores assemble on centromeres for microtubule attachment during mitosis.
  • Centromeres were once thought transcriptionally silent but produce non-coding RNAs (ncRNAs).

Purpose of the Study:

  • To review and synthesize current information on the functions of centromeric ncRNAs (cenRNAs).
  • To highlight the role of cenRNAs in centromere function and chromosome segregation.

Main Methods:

  • Literature review of experimental studies on cenRNAs.
  • Analysis of data from various species regarding cenRNA expression and function.

Main Results:

  • Centromeric regions are transcriptionally active, producing functional ncRNAs.
  • These cenRNAs are involved in essential centromere-related processes.
  • Evidence suggests conserved roles for cenRNAs in chromosome segregation across species.

Conclusions:

  • Centromeric ncRNAs are integral components of centromere function.
  • Further research into cenRNAs can elucidate mechanisms of chromosome segregation.
  • Understanding cenRNA roles has implications for genetics and cell biology.
