RNA splicing activities can be regulated in cells by various activator and repressor proteins. Which of the following proteins is a pair of different splicing activators?SC35 protein and hnRNP proteinHalf-pint protein and SF2/ASF proteinhnRNP protein and SF2/ASF proteinHalf- pint protein and hnRNP protein Solution Half-pint protein and SF2/ASF protein is a pair of different splicing activators. As both Half pint protein and SF2/ASF protein are involved in enhancing the splicing. Whereas the hnRNP proteins will repress splicing, thus all the other 3 combinations are various activator and repressor proteins..
