Solution:
4.2 x 10^6 bp/10^3 bp/seconds = 4.2 + 103 s which is 4200 seconds and equivalents to 70 minutes
In addition, assuming a pause of 2 seconds for re initiating after completing every okazaki fragment and assuming the okazaki fragments average 1000 nucleotide long.
4.2 x 10^6 bp/10^3 bp = 4200 okazaki fragments 4200 * 2 seconds = 8400 seconds which is 140 minutes or 2 hours 20 minutes of pauses alone.
Therefore, overall time would be pauses plus the 70 minutes so total time of 210 minutes. Assuming that the replisome completely disassociates from the DNA after every okazaki fragment and must spend one-minute rebinding.
4200 okazaki fragments. 60 seconds rebinding time per fragment: 4200 x 1 minute = 4200 minutes rebinding time plus 70 minutes for actual replication. 4200 minutes is 70 hours which is almost 3 days.
Answer:
The thyroid gland increase in size.
Explanation:
Iodine plays an important role in the generation of thyroid hormones and is mainly found in the soil in coastal areas and in seawater. In the developing nations, the individuals who live at high elevations or inland are generally deficient in iodine and can develop a condition known as goiters.
In the condition, the thyroid gland increases in size in an attempt to get more iodine. However, in the countries where iodine is added routinely to foods and table salt, the lack of dietary iodine is not the typical reason of goiters.
Answer:
1. As temperature and pressure increases, density increases
Explanation:
The earth is composed of three main layers: Crust, Mantle and Core. The density or mass per unit volume of the earth's layers increases as one moves from the surface towards the interior of the earth known as the core. Also, there is an increase in pressure and temperature as depth increases. There are three main sources of heat in the earth's core: (1) conserved heat from when the planet formed and coalesced, (2) heat due to friction caused by denser core material sinking to the center of the planet, and (3) heat from the decay of radioactive elements.
The earth's core is composed almost entirely of the metals, iron and nickel. The core has an inner solid layer and a molten outer core. Iron and nickel are both very dense metals, so the core of the earth is very dense and the density increases with depth with the inner core being the most dense layer of the earth.
