Exons

genomic DNA..actually genes have exons+introns...cDNA you get from mRNA(thus it contains only exons).If you mix genomic and cDNA and heat them..they will denaturate..then you lower temperature and cDNA will hybridize with genomic DNA on matching ...

Sorry, you're right, not used to this particular terminology. Like a lot of things in DNA (exons, anyone-?), it's pretty counter-intuitive.

The coding strand of the DNA is made up of introns (non-coding parts) and exons (coding parts). when the mRNA is transcripted from the DNA it includes all the corresponding parts (both the introns and exons) but then the mRNA is spliced, which is where the introns ...

hi canalon, thanks for your hints. i think i know my answer now. ub2 is not a separate gene but the exon that wasn't included in the splicing process. it was annotated as a gene, but may not necessarily a gene. although there is no cDNA in the database encoding for the gene, the 123 amino acids are ...

... Databases show that there are 3 different lengths of cDNA sequences associated with Gene YFG. One of these cDNA sequences has three out of four exons plus additional nucleotide sequence at the 3’ end of the cDNA. This part codes for an extra 123 amino acids. Annotated gene UB2, appears immediately ...
