The information contained within the gene is copied into a new molecule by the process of transcription. Transcription is a process by which the information from one strand of DNA is copied into a new molecule called messenger RNA or mRNA. Even though mRNA contains the same information it is not the exact copy of the DNA segment. Protein molecules include DNA and RNA and the genetic information is copied into the protein molecules by the process of transcription and translation. Transcription is a process by which the information coded in DNA is transferred to RNA, where as translation is a process where mRNA provides information for the Ribosome the type of amino acid to link with. As amino acids are made up of proteins there will be transfer of information contained in a gene to be transferred to protein. Whereas the function of tRNA is to carry amino acids to ribosome during the transcription hence it does not carry any genetic information where as rRNA combines with the set of proteins to form ribosomes. These rRNA molecule moves along with the mRNA molecule but does not carry any genetic information.
Therefore the answer is d
The Brain Stem connects the spinal cord to the brain.
Answer:
The correct answer is - option A. They serve as second messengers to regulate glucose uptake to cells.
Explanation:
Type one diabetes is a condition that is characterized as the inability to produce enough quantity or at all of the insulin by the beta cells of the pancreas. Therefore, a patient with this condition completely depends on exogenous insulin to maintain the sugar level in the blood.
Insulin is the hormone that removes the excess amount of glucose from the blood by the adipose tissue, liver cells, and skeletal muscle that uptake an extra amount of sugar. there are receptors present on the surface of the plasma membrane which binds with the insulin and acts as a secondary to regulate a cascade reaction to glucose uptake to cells.
The term is Facilitated diffusion.
Facilitated diffusion is a transport mechanism in which carrier proteins shuttle molecules across the cell membrane without using the cell's energy, and because it does not use the cell's energy, it is a passive transport.
The energy is provided by the concentration gradient, which means that molecules are transported from higher to lower concentrations, into or out of the cell.
The carrier proteins of the GLUT family are responsible for transporting glucose. They bind to glucose , which causes them to change shape to fit in the membrane passage then they translocate the glucose molecule from one side of the membrane to the other.
Red blood cells use facilitated diffusion to absorb glucose.
A hypothesis is a suggested explanation for an observable problem OR a reasoned prediction of a possible causal correlation among multiple problems. A theory is a tested and well substantiated and unifying explanation for a set of verified and proven factors.
