Introduction:
gene expression:
It is a process of transcription of a gene into mRNA, processing of mRNA and translating into a protein( in protein encoded genes. )
It produces the end products such as protein or non coding RNA.
The products are proteins but in the non protein coding genes, the product is functional non coding RNA.
The gene expression is utilised by prokaryotes, eukaryotes ans viruses also.

Don't forget to mention WHERE you have lived during your life, how you have moved, what helped you along the way, and all the other proteins and other small molecules you havearrow_forwardPlease answer fastarrow_forwardChoose all that apply regarding gene transcription in eukaryotes: Multiple transcription factors are necessary to form the pre-initiation complex (PIC) of RNA Pol II. The 5' cap of mRNA requires the free triphosphate on the nucleotide at the 5' end. Introns must be removed from the initial RNA transcipt. Histone acetylation is a method controlling gene expression. Acetylation creates more positive charges on histones, leading to tighter binding of the proteins to DNA. Exons are removed from mRNA by the spliceosome. RNA polymerase II must completely finish an mRNA transcript before processing can begin. RNA polymerase I catalyzes the synthesis of the majority of ribosomal RNA. The hormone 173-estradiol binds to a G-protein coupled receptor to control gene transcription.arrow_forward
