Firstly, the enzyme, DNA Helicase breaks the Hydrogen bonds between a specific region of the DNA molecule and unwinds the duplex DNA molecule at the targeted gene sequence site.
 Then, RNA Polymerase binds at the 3` site of the gene sequence of the sense/coding strand(only one strand) that acts as the template for mRNA synthesis. RNA Polymerase then matches free nucleotides by complementary base-pairing(A-U & C=G), working in the 5`to3` direction. Hydrogen bonds then form between the complementary bases, holding the nucleotides in place. Each free adjacent nucleotide is joined at 3` ends by Condensation reactions with the other to form Phosphodiester bonds.
Once the mRNA molecule is formed, it is separated from the synthesis complex and leaves the nucleus through pores in the nuclear envelope to moves towards ribosomes for Translation.
Lastly, the DNA double helix rewinds by forming Hydrogen Bonds.

A patient presents with low copper. which portion of cellular respiration would suffer?
Alex73 [517]
Copper deficiency is a rare disease that leads to hematological disorders. It is an essential trace element. It is an essential part of some enzymes (c0-factor) that plays role in cellular respiration. Copper is also an anti-oxidant that scavenges free radicals. In case of cellular respiration copper is responsible for electron transfer of oxygen.

What factor does not contribute to "water stress" on the Earth?
kotegsom [21]

Precipitation differences are the factor that does not contribute to "water stress" on the Earth.

<u>Explanation:</u>

  • Less ocean water sources, population differences, Scarcity of economic water resources are the factor which leads to water stress on the Earth.
  • Precipitation differences do not cause much difference in water stress. So it will not contribute to the water stress.
  • An increase in population will cause major water stress because availability drinking water is less in the earth. Population increase can cause a major problem.

What is a glacial sediment called? &amp; What is a large rock transported by a glacier called?
Luba_88 [7]
<span>The glacial sediment is known as glacial till.

 Glacial till is derived from entrainment and erosion of material by the moving ice of the glacier.

 It is being deposited a distance down -ice to form ground moraines, medical, lateral, and terminal. Glacial till is divided into primary deposits which are rewarded by fluvial transport.
The large rock which is transported by a glacier is called moraines. Moraines are formed from debris which is previously carried along by a glacier and consists of rounded particles which range in size from the large boulders.

 Moraines are of different types, for example, ground moraines, lateral moraines, and recessional moraine.</span>
