How to have a library of nucleic acid sequences without going on NCBI every time ?

Without knowing the full context of this question here are some general suggestions.
You could keep blast indexes for "nt"(since you asked for nucleic acids) database handy and extract sequences you need using blastdbcmd utility.
You could also use e-utils from NCBI and fetch data you need (but this can count indirectly as "going on NCBI").Last edited by GenoMax; 12-01-2015, 05:59 PM. -
I wanna check for homology between sequences based on accession numbers and be able to see alignment without going to different websites. Would that be possible with an already made program ?Comment

You are going to have to visit some websites ....
If you are working with eukaryotic genes NCBI may have already done the work for you in their homologene project in terms of multiple sequence alignments. Ensembl and UCSC also have similar results available.
On prokaryotic side you can check this site: http://mbgd.genome.ad.jp/
If you only have accession numbers then you may need to do some alignments yourself.Comment

The sequencing world is rapidly changing due to declining costs, enhanced accuracies, and the advent of newer, cutting-edge instruments. Equally important to these developments are improvements in sequencing analysis, a process that converts vast amounts of raw data into a comprehensible and meaningful form. This complex task requires expertise and the right analysis tools. In this article, we highlight the progress and innovation in sequencing analysis by reviewing several of the...05-06-2024, 07:48 AM -
The field of epigenetics has traditionally concentrated more on DNA and how changes like methylation and phosphorylation of histones impact gene expression and regulation. However, our increased understanding of RNA modifications and their importance in cellular processes has led to a rise in epitranscriptomics research. “Epitranscriptomics brings together the concepts of epigenetics and gene expression,” explained Adrien Leger, PhD, Principal Research Scientist...04-22-2024, 07:01 AM
