Epiphytes, Parasites, and Carnivores

16.9K
Plants often form mutualistic relationships with soil-dwelling fungi or bacteria to enhance their roots’ nutrient uptake ability. Root-colonizing fungi (e.g., mycorrhizae) increase a plant’s root surface area, which promotes nutrient absorption. While root-colonizing, nitrogen-fixing bacteria (e.g., rhizobia) convert atmospheric nitrogen (N2) into ammonia (NH3), making nitrogen available to plants for various biological functions. For example, nitrogen is essential for the...

DNA Topoisomerases02:02

DNA Topoisomerases

35.8K
Topoisomerases are enzymes that relax overwound DNA molecules during various cell processes, including DNA replication and transcription. These enzymes regulate positive and negative DNA supercoiling without changing the nucleotide sequence. DNA overwinding in a clockwise direction results in positively supercoiled DNA, whereas underwinding in a counterclockwise direction produces negatively supercoiled DNA.
Types and Mechanism of action
Topoisomerases are divided into two main types. ...

DNA Helicases

24.2K
DNA unwinding helicase enzymes are a type of motor protein. Motor proteins can translocate along filaments or polymers using energy generated from ATP hydrolysis. Helicases are involved in all the important cellular processes where DNA unwinding is required, such as DNA replication, repair, recombination, and transcription. They are present in all living organisms, but vary in their structure, function, and mechanism of action. For example, in prokaryotes, DnaB helicase binds and translocates...

DNA Replication02:40

DNA Replication

60.2K
DNA replication involves the separation of the two strands of the double helix, with each strand serving as a template from which the new complementary strand is copied.  After replication, each double-stranded DNA includes one parental or “old” strand and one “new” strand. This is known as semiconservative replication. The resulting DNA molecules have the same sequence and are divided equally into the two daughter cells.

DNA-only Transposons02:57

DNA-only Transposons

17.5K
DNA-only transposons are called autonomous transposons since they code for the enzyme transposase that is required for the transposition mechanism. Insertion of transposons can alter gene functions in multiple ways. They can mutate the gene, alter gene expression by introducing a novel promoter or insulator sequence, introduce new splice sites, and change the mRNA transcripts produced, or remodel chromatin structure.
The donor site from where the transposon is excised is either degraded or...

Summary

Ancient DNA barcoding overcomes technical hurdles to recover parasite DNA from diverse samples. This research offers insights into prehistoric health, extinct species

Area of Science:

  • Paleoparasitology
  • Ancient DNA Analysis
  • Molecular Ecology

Background:

  • Ancient samples pose challenges for DNA barcoding due to degraded DNA (low copy number, short fragments).
  • Despite challenges, DNA barcoding successfully recovers parasite DNA from various ancient substrates like coprolites, sediments, and permafrost.
  • Studying ancient parasite DNA provides unique insights into past ecosystems and host-parasite interactions.

Purpose of the Study:

  • To explore the application of DNA barcoding for recovering parasite DNA from ancient specimens.
  • To highlight the scientific insights gained from ancient parasite DNA analysis.
  • To discuss the potential of DNA metabarcoding and high-throughput sequencing for future ancient DNA studies.

Main Methods:

  • Application of DNA barcoding techniques to ancient samples.
