it has an alternating chemical<span> phosphate and </span>sugar<span> backbone, making the 'sides' of the ladder. (Deoxyribose is the name of the </span>sugar<span> found in the backbone of DNA.) In between the two sides of this </span>sugar<span>-phosphate backbone are four nitrogenous bases: adenine (A), thymine (T), </span>cytosine<span> (C), and guanine (G).</span>
<span>The correct answer is gold. That's why it has reserves of almost 10 000 tonnes of gold which accounts to almost a fifth of the entire world gold reserves. It is way ahead of the second placed South Africa that produces only 6 000, and Russia that does 5000. It has been going down in recent years, but it's nothing significant and will likely stay first for years to come.</span>
Okay so there are two types of ERs, smooth and rough.
Rough endoplasmic reticulum contain ribosomes on the outer surface. It provides large surface area for proteinsynthesis and the synthesis of glycoproteins and also provides a pathway for the transport of materials.
Smooth ER synthesises, stores and transports lipids and carbohydrates.
Hope this helps

The purple spots on the colorless background of corn kernels observed by Barbara McClintock were the result of the transposition of the Ds elements out of the color gene.
<h3>What are the genetic elements found in corn?</h3>
- A transposable element is removed from one spot in the DNA and inserted into a different site in the DNA during the process of genetic transposition, which allows genes to shift their location on chromosomes.
- The first recognized genetic instability was caused by genetic transposition.
- The size of the tissue patch displaying the reversion phenotype increases as a reversion event happens earlier in the kernel development.
- Barbara McClintock saw purple dots on maize kernels with an otherwise colorless background.
- These spots were caused by the Ds components of the color gene being transposed.
- The wild-type (purple) phenotype manifests itself in cells where Ds from the color gene "C" sequence has been lost.
Hence, Barbara McClintock discovered purple patches on the colorless backdrop of maize kernels due to the transposition of the Ds elements out of the color gene.
