Document Summary
Clicker question: you are looking at a sequence of dna that is transcribed in both males and females but translated only in females. What kind of sequence is it: 5" utr, bicoid mrna. Transcribed by females in order to pack it into their eggs but those eggs could be male or female once they"re fertilized. Both males and females will translate the bicoid mrna: gene on x chromosome, alternatively spliced intron. Spliced different in males and females, transcribed in both but only translated in females. Clicker question: which of the following gene expression components: Results from transcription of dna and is understood by the cell as rna: transcription terminator hairpin, oncomir, sd box, polya-tail. Mental floss: how might hpv cause cancer without causing mutations? sirna from virus causes rnai that interferes with the translation of a mrna coding for tumour suppressor. Basic mechanism of propagation of action potentials in neurons. Action potentials are propagated by movement of ions across membranes.
