From which human gene is the above mRNA transcribed?
Homework Answers
Quaternary protein structure is correct for the general transcription factor TFIID. The quaternary structure of a protein involves the clustering of several individual peptides into a final shape. The bonds involved in this structure are hydrogen bonds, salt bridges, and disulphide bonds.
The amino acid sequence is
GL(stop)RPPIKET

1) The FOXP2 transcription factor is expressed in human brain, heart, and lungs. The protein is required for normal development. Given that eukaryotic genes do not occur in operons, how can the STAT 1 transcription factor simultaneously regulate the transcription of more than 275 different target genes? 2) Many genes are transcribed constitutively, while others are regulated specifically. Regulation can occur in response to various stimuli in either a positive or negative direction. Describe one type of gene that would...
