he DNA site that is bound by a transcriptional activator regulates gene expression in a) cisb) trans

Post-translational control refers to: a. regulation of gene expression after transcription b. regulation of gene expression after translation c. control of epigenetic activation d. period between transcription and translation

Which statement is false: A) Each type of protein ( ex: hemoglobin vs trypsionngen) varies in the length and amino acid sequence of its peptide B) After the rpocess of transcription is complete, the mRNA that is produced will continue being tranlsated by ribosomes for the rest of the cells life. mRNA never breaks down C) A ribosome will bind to an mRNA and will translate the sequence by reading one codon at a time and adding one amino acid to the peptide chain. It will stop the translation once it encounters a stop codon  D) The gene for a protein provides the information on the legth of the peptide, along w the amino acid sequence so the protein can be synthesized by a ribosome  E) Once mRNA has left the nucleus, ribosomes will bind to it and will follow the instructions in its sequence to make the new protien

a) Describe how mRNA and tRNA interact. b)Translate the following mRNA codons: AUG GUU AAC CAG UGA c) What are transcription factors made of?
