5. The transcribed portion of a gene spans about 250,000 base pairs of DNA. The protein made from this gene, with 1,480 amino ac

ids, is translated from an mRNA of about 6,500 bases. a. Why is the coding sequence of this gene so much larger than the mRNA from which the protein is translated?

Answer:

The nature of genes made them be divided into exons, introns and different regulatory sequences

Explanation:

The amount of genetic information that is under a gene structure have different roles in order to be correctly read. When a mRNA is produced from a certain gene, some regions from the complete structure of a gene might not be transcribed into a mRNA, and therefore won't be expressed into a protein. One of the main reasons of the smaller size in number of base pairs is because some of those lost regions on the DNA structure are responsible to be regulatory sequences and so, those sequences are not related with the final structure the mRNA and subsequently the protein structure. Some of those regulatory regions are related with the speed of transcription, for instance.

Which trace mineral is needed for the regulation of protein synthesis and reproduction and immune functions?A. ironB. zincC. cop
STALIN [3.7K]

Answer:

Zinc. (Ans. B)

Explanation:

Trace minerals: Trace minerals are defined as the inorganic molecules which are necessary for the human body for the different functions.

Zinc function in human metabolism is defined as a cofactor for numerous enzymes. Zinc play a role as a catalyst in a broad range of reactions. It is involved in the metabolic pathway directly or indirectly with lipids, carbohydrates, proteins, energy metabolism, and they are also important for the cell division process.

They also need for tissue and growth repair, and for reproductive development also. It's also played a vital role in immune system such as wound healing or required for the function and structure of the skin.

Need to write a short news report on how does the brain he brain, heart and skeleton work together
Kitty [74]

The brain, heart and the skeleton are the integral parts of the nervous system, circulatory system and the skeletal system respectively. The nervous system is made of the brain and the spinal cord with neurons as the structural and functional units of it. The circulatory system is made up of the heart and its blood vessels. The skeletal system is made up of the bones and cartilages making the skeleton of the body.

The brain regulates the heart beat and the blood pressure. The heart nourishes the brain with oxygen and nutrients by pumping blood. The bone cells are nourished by the blood pumped by the heart. The bone marrow of the skeleton produces the new red blood cells which enter the blood circulatory system. Also the the ribs and the breast bone of the skeleton protects the heart, the cranium of the skeleton prtects the brain. The bones also provide calcium which is necessory for the functioning of the nervous system. The brain controls the skeletal movements of the body. The cerebellum of the brain controls the voluntary skeletal movements and the medulla controls the involuntary skeletal movements of the body. The blood brain barrier formed by the endothelial cells of the capillary walls located in the brain seperates the circulating blood from the brain and the extraclellular fluid in the central nervous system and acts as a selective semipermeable border.
