NCBI Minute: A Beginner's Guide to Genes and Sequences at NCBI

Presented September 11, 2019.
Interested in learning about genes and sequences but don't know how to begin? This webinar, intended for people with limited experience working with sequence information, will provide you with basic knowledge on how to find and compare nucleotide and protein sequences. You will learn about the kinds of data available for genes and sequences, how to select the most informative records, and how to find related genes and sequences using pre-computed information and the BLAST sequence search service.

Thank you so much! I was absolutely lost for a bioinformatics assignment, and this video truly made me more confident!

[@morganreese7]

Yessss! Same here this helped tremendously for my presentation today!

THAT IS GREAT CHANNEL

[@dukherdohonekorunrodone6346]

it'd be helpful if you could use your mouse pointer to show what part of the slide you are focusing on.

Thank you very much for detailed explanation, very helpful !

Thank for the video I have a question about Refseq When I search for a gene in the gene database I find that the number of exons in that gene is a specific number but when I go to the RefSeq of that gene I find that the number of exons is different, can anyone explain that for me

Hi, thank you for this video, I am working on genes associated with schistosomiasis and its resistance, how do I go about it and How do I have your videos that will guide me through

VERY GOOD LECTURE

[@ayudashintastri1952]

Thank you very much Sir for your good video

[@ongerijustineonderi2208]

Hey friend, how can I get to see the hits of nucleotide BRCA2, I don't know how to check hits

Gene structuring or enhancement

Great! thank you

[@hasanashfaq3853]

I have question sir, if I want to characterize a gene on molecular basis, but the gene, I am searching for appear to pop up containing different variants starting with i.e. XP, but no NP sequence, which sequence should I use to design primers, please answer.

Sir Francis Crick called that...

I followed through this lecture in Aug. 2020 and cannot find E. coli that appears in the video at 24:11. It doesn't matter to me if E. coli is in the list of blast against human APRT (not the protein of my interest), but I wonder what made this difference in the query results. Is it updates in E. coli DB? I'd like to know why it happened in order to fully understand the NCBI platform.

[@LatterDayYouth]

One more question. The active site annotation doesn't come up when I click on the 'Functional sites' annotations unlike the video, 25:55 . Could you help me?

This tutorial is quite bad... The quality of sound and the process, it's like: it is science! It should be only complicated and very scientific!!! (I get the mechanism of this part of databases although the tutorials for this topic are horrible, especially from NIH itself.) There should be more practical stuff and less "just sciencitific X,Y,Z search", I think.
