Genes encode proteins and proteins dictate cell function ... sites in the DNA that effectively block RNA polymerase binding (Figure 3). The control of gene expression in eukaryotes is more ...

Biology lectures teach students that when a cell’s replication machinery comes together, DNA polymerase takes off down the double-helix like a car on a highway ...

Gene expression is linked to RNA transcription, which cannot happen without RNA polymerase ... who study the regulation of eukaryotic gene expression, and its function is well understood.

Genetic material DNA in a nucleus, plasmids are found in a few simple eukaryotic organisms. DNA is a single molecule, found free in the cytoplasm; additional DNA is found on one or more rings ...

The genetic connections between DNA ... eukaryotic cellular DNA ligases, it can sustain mitotic growth, DNA repair, and nonhomologous end joining in budding yeast when it is the only source of ligase ...

The process of transcription elongation by RNA polymerase II (Pol II), in which Pol II travels along DNA and synthesizes RNA from DNA, is essential for proper gene expression in all eukaryotic cells.

However, the behind-the-scenes process of analyzing forensic DNA is far more intricate, requiring careful interpretation of the data. Forensic DNA profiling uses polymerase chain ... Additionally, ...
