The best choice is A.
A gene is a specific sequence of nucleotides in DNA or RNA that is located usually on a chromosome and that specifies the structure of a particular polypeptide and especially a protein, or controls the function of other genetic material.
Information from the gene is copied (transcribed) on mRNA in the nucleus. mRNA then leaves the nucleus and enters the cytoplasm where it attaches to a ribosome. The information on the attached mRNA is decoded (translated) by tRNA which then fetches the amino acids according to this information and brings them to the ribosome where they are linked together to form the specified protein.
it should be C. scientific
Answer:
The muscular dystrophy may be defined as the medical condition that leads to the weakening of the muscle and reduction in the muscle weight and loss of motor control.
The muscular dystrophy is the autosomal recessive disease. THis occur due to the mutation in the amino acids and arginine is replaced with histidine. The arginine pKa value is high whereas histidine pKa value is nearly upto 6-7. This disrupt the physiology of the proteins, disrupt its structure and result in the formation of misleading protein.
