Dictionary » D » Downstream DownstreamDownstream 1. (Science: molecular biology) portions of dna or rna that are more remote from the initiation sites and that will therefore be translated or transcribed later. 2. Shorthand term for things that happen at a late stage in a sequence of reactions. ![]()

Results from our forumRe: Retained Intron through Translation... intron is included, you are likely to have a stop codon in-frame in the intron. This triggers nonsense-mediated decay of the mRNA. Frameshifting downstream sequence by including an intron with a number of bases not evenly divisible by three will also likely bring a stop codon in-frame in the ...

introns and exons... additional nucleotide sequence at the 3’ end of the cDNA. This part codes for an extra 123 amino acids. Annotated gene UB2, appears immediately downstream of YFG. UB2 has a single exon coding for 123 amino acids matching the cDNA. There is no cDNA in your database encoding for a UB2 gene with ...

introns and exons... It would appear that we are taking the same module. I came online to look for solutions and stumbled on your post. How does appearing immediately downstream justify it not being a separate stream? in any case, downstream is 5' to 3' i'm quite sure. may I add that this module has turned me off ...

When are parts of prokaryotic operons seperated?... is not always true. sometimes an ORF(open reading frame) lacks a ribosome binding site and is only actively transcribed by virtue of the being downstream of a gene with a strong RBS. in these cases, the start codon of the downstream ORF often overlaps the 3' end of the upstream ORF(most often ...
