Answer:
b. Elongation
Explanation:
During the start of the elongation phase of RNA synthesis, the sigma subunit of RNA polymerase of <em>E. coli</em> is released and NusA protein takes its place. This makes the RNA polymerase to move away from the promoter.
During the elongation phase of RNA synthesis, the enzyme DNA dependent RNA polymerase elongates the RNA strand by addition of ribonucleotides to the free 3'-OH end. The process occurs in 5' to 3' direction and the 3'-OH group serves as a nucleophile.
The correct answer is it decreases genetic diversity only by reducing population size.
<span>
The great explanation for this is a bottleneck effect, which is an extreme example of genetic drift. The bottleneck effect occurs when the size of a population is reduced due to a catastrophe. When it happens, only a small, random number of individuals survive the event and pass through the bottleneck. Thus, the genetic composition of the random survivors is now the genetic composition of the entire population which means that the genetic diversity is reduced.</span>
Answer:
An atom is stable if the forces among the particles that makeup the nucleus are balanced. An atom is unstable (radioactive) if these forces are unbalanced; if the nucleus has an excess of internal energy. Instability of an atom's nucleus may result from an excess of either neutrons or protons.
Explanation:
Answer:
Oil
Explanation:
Oil is the most common fossil fuel internationally, seeing as it is in the top spot for usefulness.
Answer:
NON REUSEABLE
Explanation:
There are four major types of nonrenewable resources: oil, natural gas, coal, and nuclear energy. Oil, natural gas, and coal are collectively called fossil fuels
