Which of the following types of RNA is responsible for helping to reestablish methylation patterns during gamete formation? O piRNA O MİRNA O IncRNA O SİRNA O ERNA

In eukaryotic cells, which of the following is typical of how transcription is regulated? Group of answer choices Activators and enhancers at sites distant from structural genes interact to increase or decrease transcription Regulatory genes are always tightly coupled in physical proximity to the structural genes they regulate There are only a few transcription factors that are functional in eukarya Attenuation, where translation and transcription are tightly coupled, is common.

Please draw the mature mRNA (before it is ready to be exported from nucleus):

19

There is a situation in which a gene has five exons. Please draw four possible mature products of the gene if there is alternative splicing.

From the list given - choose all of the regulatory proteins that would bind the eukaryotic gene to control its expression THERE ARE MULTIPLE ANSWER TO THE QUESTION    Group of answer choices A RNA polymerase II B 3' UTR C mediator protein D 5' UTR E activators F coding sequence G specific transcription factors H general transcription factors
