|April 9, 2010
Summary
Telomeres protect chromosome ends, but were thought silent. Recent studies reveal telomeric repeat-containing RNAs (TERRAs) in vertebrates and yeast, challenging this view and prompting research into TERRA expression control.
Area of Science:
- Molecular Biology
- Genetics
- Epigenetics
Background:
- Telomeres are crucial for chromosome stability, protecting linear chromosome ends from DNA damage.
- Telomeres were traditionally considered transcriptionally silent regions of the genome.
Purpose of the Study:
- To summarize recent advancements in telomere research.
- To highlight the discovery and implications of telomeric repeat-containing RNAs (TERRAs).
- To explore mechanisms regulating TERRA expression.
Main Methods:
- Literature review of recent publications on telomere biology and RNA transcription.
- Analysis of studies identifying and characterizing TERRAs in various organisms.
Main Results:
- Recent research has identified telomeric repeat-containing RNAs (TERRAs) in both vertebrates and yeast.
- The existence of TERRAs challenges the long-held notion of telomere transcriptional silence.
- TERRAs are implicated in telomere maintenance and regulation.
Conclusions:
- Telomeres are not transcriptionally silent, as evidenced by the discovery of TERRAs.
- Understanding TERRA expression mechanisms is a key area of ongoing telomere research.
- TERRAs represent a novel layer of regulation in maintaining chromosome stability.

02:41Telomeres and Telomerase
In eukaryotic DNA replication, a single-stranded DNA fragment remains at the end of a chromosome after the removal of the final primer. This section of DNA cannot be replicated in the same manner as the rest of the strand because there is no 3’ end to which the newly synthesized DNA can attach. This non-replicated fragment results in gradual loss of the chromosomal DNA during each cell duplication. Additionally, it can induce a DNA damage response by enzymes that recognize single-stranded DNA.

01:29Replication in Eukaryotes
In eukaryotic cells, DNA replication is highly conserved and tightly regulated. Multiple linear chromosomes must be duplicated with high fidelity before cell division, so there are many proteins that fulfill specialized roles in the replication process. Replication occurs in three phases: initiation, elongation, and termination, and ends with two complete sets of chromosomes in the nucleus.

Overview
02:39lncRNA - Long Non-coding RNAs
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 (lncRNA)...
02:57piRNA - Piwi-interacting RNAs
PIWI-interacting RNAs, or piRNAs, are the most abundant short non-coding RNAs. More than 20,000 genes have been found in humans that code for piRNAs while only 2000 genes have been found for miRNAs. piRNAs can act at the transcriptional and post-transcriptional levels and have a vital role in silencing transposable elements present in germ cells. They are also involved in epigenetic silencing and activation. Previously, they were thought to function only in germ cells but new evidence suggests...
