Answer:
Since DNA is double-stranded, two different RNA molecules could in principle be transcribed from any gene, using each of the two DNA strands as a template.
Explanation:
During transcription, the DNA of a gene serves as a template for complementary base-pairing, and an enzyme called RNA polymerase II catalyzes the formation of a pre-mRNA molecule, which is then processed to form mature mRNA
Atoms may have different numbers of neutrons. Atoms are the smallest fraction of an element that can exist, and still show the properties of the element. They consists of electrons (negatively charged), protons (positively charged), and neutrons (no charge). The number of electrons is equivalent to the number of protons normally however an atom may loose or pick up electrons and have a positive charge or negative charge. The number of neutrons in the nucleus may vary within a given element to give varieties of atoms we call isotopes.
Answer:
Sigma factors bind to the promoter region of a particular gene and facilitating the binding of RNA Polymerase to the promoter region (formation of the RNA polymerase holoenzyme complex) in order initiate transcription of the gene.
Put simply - Helps RNA Polymerase do it's job.
Answer:
Planet X has a moon similar to Earth's moon.
Which path would this moon's orbit take? <u><em>3</em></u>
If for some reason, the planet is destroyed and no
longer exists, which path would the moon take? <u><em>2</em></u>
Explanation:
There are none of these planets in our solar system. But they might exist in other star systems. There, some moons might escape their parent planets’ gravity and start orbiting their parent stars instead. That’s according to new computer simulations. Scientists have dubbed the liberated worlds “ploonets.” And, the scientists say, current telescopes may be able to find the wayward objects.
