You should now be able to view only the protein sequence without any context of the gene it came from.Ĭheck out the tab “Biochemical Properties” to see some computed values that Benchling calculates about this unique protein such as “Molecular Weight”, “Isoelectric Point”, “Extinction Coefficient” Specify where you’d like to save the new sequence and then rename the sequence “BRCA2 H. Select the ORF encoding the entire protein and right click and choose “Create AA sequence” -> “Forward”. Sapiens) DNA sequence, do the following to create a protein sequence: Now that you’ve familiarized yourself with looking at genes and understanding the proteins they encode as a DNA sequence, we’ll explore how you can create a corresponding Protein sequence directly on Benchling and analyze them by protein alignments. Import the BRCA2 gene into a Project of your choice along with the following settings and inputs:īrowse through the respective sequences and even from a glance, you will notice that the protein sequences across organisms are very different.

In this example, we’ll investigate the human BRCA2 gene and understand how to generate its corresponding protein sequence on Benchling and analyze it.įor eukaryotic genes, external databases will allow you to import the full genomic DNA sequence (including exons and introns) or import only the coding DNA sequence (exons only) that comprise the protein. Better yet, it can help you easily visualize the relationship between a gene and it’s protein counterpart. Mutate or change codons for individual amino acidsĬreate and analyze a protein sequence on Benchlingīenchling is a great tool for designing or storing DNA and protein sequences. Learning outcomesĪdd or remove translation frames over DNA sequences For a quick overview of proteins and their properties, check out this video. Additionally, you should have awareness of biochemical properties of proteins such as structure, function, folding, isoelectric point (pI), and so on. You should have a fundamental understanding of the central dogma and how genes can encode for a specific, functional protein. While many earlier modules have covered how to create and visualize DNA sequences (genes, plasmids, and templates), this module will cover how to generate and analyze protein sequences on Benchling. The complex relationships between DNA, RNA, and proteins also mean there are complexities with storing and analyzing those corresponding sequences for experimental purposes as well. The central dogma of molecular biology is an essential learning for any scientist. Philip Leftwich, Biology Lecturer at the University of East Anglia (Norwich, UK) Overview For notebook entries, you can manually copy & paste the content into a new blank entry.Ĭontent and materials for this module were co-developed with Dr. DNA sequences can be copied directly into your Benchling account.
