Summary
Forensic botany can now use DNA profiling of oak (Quercus spp.) with seven Short Tandem Repeat (STR) markers. This method aids in comparing plant evidence from crime scenes to develop reliable genetic profiles.
Area of Science:
- Forensic Science
- Molecular Biology
- Botany
Background:
- Forensic botany requires reliable methods for verifying plant-origin evidence.
- Molecular biology techniques offer powerful tools for comparing biological evidence.
Purpose of the Study:
- To develop a DNA profiling method for oak (Quercus spp.) using Short Tandem Repeat (STR) loci.
- To establish a set of seven highly polymorphic STR markers for forensic applications.
Main Methods:
- Selected seven STR loci with high heterozygosity from existing literature.
- Verified primer specificity across 23 oak species.
- Utilized multiplex PCR for amplification and capillary electrophoresis for analysis.
Main Results:
- Successfully obtained full genetic profiles for 13 out of 23 investigated oak species.
- Demonstrated the utility of the developed STR markers for oak DNA profiling.
Conclusions:
- The developed method provides a valuable tool for forensic botany.
- Incomplete profiles in some species may be attributed to DNA degradation or storage issues, highlighting the importance of sample quality.

Ribosome Profiling
4.2K
Ribosome profiling or ribo-sequencing is a deep sequencing technique that produces a snapshot of active translation in a cell. It selectively sequences the mRNAs protected by ribosomes to get an insight into a cell’s translation landscape at any given point in time.
Applications of ribosome profiling
Ribosome profiling has many applications, including in vivo monitoring of translation inside a particular organ or tissue type and quantifying new protein synthesis levels.

DNA Topoisomerases
35.7K
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 Replication
59.7K
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 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.
