Structure of Eurkaryotic Gene Flashcards
1
Q
Early estimates of gene number varied widely. What do whole genome sequences that have been annotated for genes tell us about actual numbers of genes, and what kinds of genes they are?
A
about 40,000 human genes in total; 26,000 protein coding, the rest make RNA
2
Q
Where is the transcriptional start site?
A
the beginning of the 5’ untranslated region
3
Q
Where is the start codon?
A
the end of the 5’ untranslated region
4
Q
What is the transcriptional start site?
A
the beginning of transcription, located at the very beginning of an untranslated region
5
Q
What do transcription factors do?
A
regulate gene expression
