The correct answer is: c. The DNA strand begins to unwind, separating the two strands.

Transcription is the first step of gene expression in which DNA molecule is copied (transcribed) into RNA (mRNA) by RNA polymerase. The process of transcription is divided into three phases:

1. Initiation

• RNA polymerase with transcriptional factors bind to gene promoter

• RNA polymerase unwinds DNA double helix (transcription bubble is formed)

2. Elongation

• RNA polymerases adds nucleotides complementary to DNA  

3. Termination

• RNA polymerase gets to stop codon (transcribes a sequence of DNA known as a terminator)

• Formed complementary RNA strand is released from DNA-RNA complex

Yeasts reproduce by budding. During budding, a yeast cell splits into two cells. Then the two cells split, making four cells. De
Vera_Pavlovna [14]

Answer:

20 yeast cells would be formed.

Explanation:

You have five cells. Each of those five cells split into two, so now we have 10 cells. Think about it like multiplication, so 5 times 2 = 10. Now we have 10 cells. We know that they split even further, so now those 10 cells become 20 cells. Here is a more simple explanation:

5 cells:

*        *        *        *        *

Now those five cells split up into 2:

*       *        *       *       *

* *     * *     * *     * *     * *

Then those new ten cells split into four:

   *          *            *            *          *

  * *        * *          * *         * *        * *

* * * *    * * * *     * * * *    * * * *    * * * *

Add 4+4+4+4+4 = 20 or 4 times 5 which would also equal 20.

And that is the answer, hope that helped :)

The suns density is greatest in which region
Bingel [31]

The sun is most dense at its core.  It forms 10% of the sun's mass.   Because of the enormous amount of gravity compression from all of the layers above it, the core is very hot and dense.

The sun's core is about 16 million K and has a density around 160 times that of water. This is over 20 times denser than the dense metal iron which has a density of 7 times that of water.  However the sun's interior is still gaseous all the way to the very center  because of the extreme temperatures. There is no molten rock like that found in the interior of the earth.

What are the environmental issues with road salt?
Basile [38]

Answer:

Salt leaves the road and enters the environment by splash and spray from vehicles, transportation by wind, snow melt into the soil and as runoff to surface waters. Salt primarily causes dehydration which leads to foliage damage but also causes osmotic stress that harms root growth.
