Answer:
Paget's disease
Explanation:
It is a chronic condition of bones understood as a disorder of the normal bone remodeling and recycling processes.
Paget's disease results in irregular thickening of bone tissue due to new bone tissue gradually replaces old bone tissue.
Paget's disease commonly affects pelvis, skull spine and legs, causing pain and deformity in them.
It also produces broken bones, hearing loss pinched nerves in the spine due to this disease increases with age.
Answer:
Watson and Crick discovered that DNA has a double helix shape, consisting of two polynucleotide chains held together by bonds between complementary bases. DNA replication is semi-conservative: half of the parent DNA molecule is conserved in each of the two daughter DNA molecules.

The exons of the pre -mRNA contain the protein -coding regions.
Pre mRNA is the first made mRNA transcript and requires undergo many post transcriptional modifications for the formation of a mature mRNA.
The exons are the regions of the pre-mRNA that are found in the mature RNA, after the splicing of introns takes place.
RNA splicing is the process in which the non-coding segments of the RNA, which are known as introns, are removed by the help of small nuclear ribonucleoproteins. These SnRNPs make the spliceosome, which catalyzes the process of splicing.
After the introns are removed by the splicing process, the exons are covalently joined, which forms the mature mRNA.

Explanation:
Evolution involves changing the hereditary characteristics of a population through generations. These traits are the expression of genes that are passed on to offspring during reproduction.
