The primary database where investigators submit DNA sequences to NCBI is
| Uniprot |
| Genbank |
| RefSeq |
| PubMed |
Answer:Genbank
Genbank devloped in 1992 started collection of genes and maintain genebank from each laboratories. These all services were processed through the website by NCBI Home page.

Use BLAST to find DNA sequences in databases Perform a BLAST search as follows: Do an Internet search for “ncbi blast”. Click on the link for the result: BLAST: Basic Local Alignment Search Tool. Under the heading “Basic BLAST,” click on “nucleotide blast”. pMCT118_F 5’- GAAACTGGCCTCCAAACACTGCCCGCCG -3’ (forward primer) pMCT118_R 5’- GTCTTGTTGGAGATGCACGTGCCCCTTGC -3’ (reverse primer) Enter the pMCT118 primer (query) into the search window. (see Moodle metacourse page for the file – just copy and paste the sequence into the...

Genes in eukaryotes are often organized into exons and intrans, which require splicing to produce an mRNA that can be translated. The gene organization is the order of the DNA segments that comprise the gene starting with the promoter, the first exon, the first intron, the second exon, and so on. The interspersed intrans can make gene identification difficult in eukaryotesparticularly in higher eukaryotes with many introns and alternative spliced mRNAs. Prediction of many genes and their organization has been...

25. Trinucleotide repeat regions in DNA sequences where the repeat region can hydrogen bond into a single-stranded stem-loop structure often lead to mutations. a. Frameshift b. Transition c. Transversion d. Base substitution 26. The following graph shows two very similar populations: population a and population b. Assuming all else is equal between these populations aside from what is in the graphs, which population's trait value (i.e., phenotype for a particular trait) would you expect to change over time...
