Choose 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 controllo 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.

Bacterial Genomics

The study of the morphological, physiological, and evolutionary aspects of the bacterial genome is referred to as bacterial genomics. This subdisciplinary field aids in understanding how genes are assembled into genomes. Further, bacterial or microbial genomics has helped researchers in understanding the pathogenicity of bacteria and other microbes.

Transformation Experiment in Bacteria

In the discovery of genetic material, the experiment conducted by Frederick Griffith on Streptococcus pneumonia proved to be a stepping stone.

Plasmids and Vectors

The DNA molecule that exists in a circular shape and is smaller in size which is capable of its replication is called Plasmids. In other words, it is called extra-chromosomal plasmid DNA. Vectors are the molecule which is capable of carrying genetic material which can be transferred into another cell and further carry out replication and expression. Plasmids can act as vectors.
