Consider the predominant types of alternative splicing events that occur in mammals. Which of the following choices represent mR

NA molecules that could be produced from the primary RNA transcript by alternative RNA splicing? (In each choice, the yellow part on the left represents the 5' cap, and the yellow part on the right represents the poly-A tail.) Select all that apply.

As the question is incomplete i have added the complete question in ask for detail section.

Answer:

The correct options are:

A-C-E-G-I

A-C-E-I

A-C-G-I

Explanation:

Alternative splicing of RNA produces many mRNA strands from primary RNA transcript. When alternative splicing of RNA occurs, all the introns and some exons are removed. The removal of these exons produces different mRNA strands which are then translated into diffident kinds of proteins. Alternative splicing of RNA can highly increase the number of new produced proteins from same gene.

What is a triacylglycerol ? Discuss the advantages of organisms having triacylglycerol as energy storage molecule?
Sergeeva-Olga [200]

Answer:

Triacylglycerols are acylglycerols with three fatty acid molecules, generally long chain, which can be the same or different; we speak of simple triacylglycerols when there is the same fatty acid in all three glycerol positions, but most are mixed triacylglycerols, with at least two different fatty acids. The properties of triacylglycerols will depend on the type of fatty acids they contain.

Most of the fats and oils of both animal origin (tallow, butter) and vegetable (olive, corn, sunflower, palm, and coconut oils) are formed almost exclusively by triacylglycerols.

Physiologically, triacylglycerols are an important energy reserve. In most eukaryotic cells, triacylglycerols are stored in the cytosol as microscopic fat droplets. In vertebrates there are specialized cells in the storage of fat, adipocytes. In humans, the presence of fatty tissue under the skin, in the abdominal cavity and in the mammary gland stands out.

The purple spots on colorless background of corn kernels observed by barbara mcclintock were the result of _______.
vitfil [10]

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.
