Prokaryotic Gene Structure and Organization01:28

Prokaryotic Gene Structure and Organization

Prokaryotic genomes exhibit a streamlined organization of coding and non-coding regions essential for gene expression and protein synthesis. While coding regions contain the genetic instructions for proteins or functional RNAs, non-coding regions regulate the precise transcription and translation of these genes.Coding Regions: Proteins and RNAsThe primary coding regions, known as structural genes, include sequences transcribed into messenger RNA (mRNA) and ultimately translated into...

The Central Dogma01:20

The Central Dogma

The central dogma explains the flow of genetic information from DNA nucleotides to the amino acid sequence of proteins.
RNA is the Missing Link Between DNA and Proteins
In the early 1900s, scientists discovered that DNA stores all the information needed for cellular functions and that proteins perform most of these functions. However, the mechanisms of converting genetic information into functional proteins remained unknown for many years. Initially, it was believed that a single gene is...

Overview
lncRNA - Long Non-coding RNAs02:39

lncRNA - 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)...

Area of Science:

  • Genomics
  • Molecular Biology
  • Gene Regulation

Background:

  • Eukaryotic genomes contain a vast non-coding region, extensively transcribed into functional non-coding RNAs (ncRNAs).
  • ncRNAs play critical roles in gene regulation at both transcriptional and post-transcriptional levels.
  • Recent advancements in bioinformatics and sequencing have revealed the diversity and importance of ncRNAs.

Purpose of the Study:

  • To review the diverse roles of microRNAs (miRNAs) and other small ncRNAs in reproductive physiology.
  • To focus on their implications in animal models, particularly for ruminant reproductive biology.

Main Methods:

  • Literature review of recent research on ncRNAs, with a focus on miRNAs.
  • Analysis of studies utilizing animal models to investigate reproductive functions.

Main Results:

  • ncRNAs, especially miRNAs, are involved in the physiological regulation of reproductive tissues (testis, ovary, endometrium, oviduct) and cells (sperm, oocytes).
  • miRNAs are implicated in embryonic development and have potential roles in disease and fertility.
  • Small ncRNAs exhibit diverse functions in eukaryotic gene regulation.

Conclusions:

  • MicroRNAs (miRNAs) are key regulators of reproductive processes in animals.
  • Understanding ncRNA functions in reproduction has significant implications for animal reproductive biology and fertility.
