From DNA to Protein

20.7K
The flow of genetic information in cells from DNA to mRNA to protein is described by the central dogma, which states that genes specify the sequence of mRNAs, which in turn specify the sequence of amino acids making up all proteins. The decoding of one molecule to another is performed by specific proteins and RNAs. Because the information stored in DNA is so central to cellular function, it makes intuitive sense that the cell would make mRNA copies of this information for protein synthesis...

Transfer RNA Synthesis

10.2K
One of the unique features of tRNA is the presence of modified bases. In some tRNAs, modified bases account for nearly 20% of the total bases in the molecule. Altogether, these unusual bases protect the tRNA from enzymatic degradation by RNases.
Each of these chemical modifications is carried by a specific enzyme, post-transcription. All of these enzymes have unique base and site-specificity. Methylation, the most common chemical modification, is carried by at least nine different enzymes, with...

Nonsense-mediated mRNA Decay02:27

Nonsense-mediated mRNA Decay

9.4K
The Upf proteins that carry out nonsense-mediated decay (NMD) are found in all eukaryotic organisms, including humans. Each protein has an individual role, but they need to work in collaboration. Upf1 is an ATP-dependent RNA helicase that unwinds the RNA helix. Because Upf1 can unwind any RNA, Upf2 and Upf3 are required to help Upf1 discriminate between nonsense and normal mRNAs.
Usually, Upf3 binds to an Exon Junction Complex (EJC) at mRNA splice sites. If a ribosome fully translates the mRNA,...

Leaky Scanning02:28

Leaky Scanning

4.5K
During most eukaryotic translation processes, the small 40S ribosome subunit scans an mRNA from its 5' end until it encounters the first start AUG codon. The large 60S ribosomal subunit then joins the smaller one to initiate protein synthesis. The location of the translation initiation is largely determined by the nucleotides near the start codon as there may be multiple translation initiation sites present on the mRNA.  Marilyn Kozak discovered that the sequence RCCAUGG (where R...

Comparing Copy Number Variations and SNPs02:26

Comparing Copy Number Variations and SNPs

11.6K
Sequencing of the human genome has opened up several best-kept secrets of the genome. Scientists have identified thousands of genome variations that exist within a population. These variations can be a single nucleotide or a larger chromosomal variation.
Copy number variations or CNVs are the structural variations that cover more than 1kb of DNA sequence. The single nucleotide polymorphism (SNP), on the other hand, is a single nucleotide change or a point mutation that is found in more than 1%...

Area of Science:

  • Molecular Biology
  • Genomics
  • Bioinformatics

Background:

  • Protein synthesis involves ribosomes reading codons (three nucleotides) to add amino acids.
  • Synonymous codons, which code for the same amino acid, are not used equally within a genome.
  • This uneven usage is known as codon usage bias (CUB), a widespread phenomenon with significant implications.

Purpose of the Study:

  • To present a standardized protocol for estimating codon usage bias (CUB).
  • To provide a practical example of CUB estimation using the Codon Usage Analyzer software.
  • To facilitate further research into the causes and consequences of CUB.

Main Methods:

  • Utilizing the free software Codon Usage Analyzer.
  • Employing basic command-line skills for data and software management.
  • Following a four-step protocol: data/software download, environment setup, data preparation, and CUB estimation.

Main Results:

  • A clear protocol for estimating CUB was successfully developed and applied.
  • The protocol was demonstrated using the plant species Brachypodium distachyon as a model.

Conclusions:

  • The presented protocol offers a accessible method for researchers to study codon usage bias.
  • The Codon Usage Analyzer is a valuable tool for investigating CUB.
