Answer:
Existen células sin núcleo?, ¿Qué característica importante debieron adquirir las células que constituyeron los primeros seres vivos pluricelulares?
Explanation:
Question 1:
Exons are gene fragments whose DNA sequence after transcription is found in mature mRNAs. This part of the gene is most often coding.
The size of the exons in the genomes follows a log-normal distribution, with an average length of about 150 nucleotides, knowing that in eukaryotes, each gene contains several exons and introns (an average of 8) so the size is 8*150 = 1200 bp.
Question 2:
Introns are fragment of a gene located between two exons. Introns are present in immature mRNA and absent in mature mRNA. "Non-coding" fragment of the gene.
The introns average in a gene is 3365 bp including 3'UTR and 5'UTR and intermediate introns.
<u>Outcome of pancreaticoduodenectomy procedure -</u>
- Compared to the Whipple surgery, PPPD causes more instances of postoperative delayed stomach emptying.
- Both procedures result in comparable long-term nutritional benefits, only a small percentage of patients develop new insulin dependent, and 65% of chosen individuals experience an equivalent level of pain reduction.
- Patients who have excessive pathology in the head of the pancreas are more likely to get effective pain reduction.
What is pancreaticoduodenectomy procedure?
- A Whipple procedure also known as a pancreaticoduodenectomy is a complex operation to remove the head of the pancreas, the first part of the small intestine (duodenum), the gallbladder and the bile duct.
- The Whipple procedure is used to treat tumors and other disorders of the pancreas, intestine and bile duct.

Answer:
Arthroplasty
Explanation:
The restoration of function of a joint is called Arthroplasty. The bone functions are restored by maintaining the bones through resurfacing. Some times artificial joints are also used instead of resurfacing the existing bones.
Arthroplasty is a method to cure Osteoarthritis, or degenerative joint disease where joint cartilages reduces with age.
Also when medical treatments no longer make any impact on the joints of bone pain then Arthroplasty is done.
