Answer:
d) a polypeptide missing an amino acid.
Explanation:
Deletion is a type of mutation when one or more codons from the reading frame are removed. This results in the production of a relatively shorter mRNA that lacks one or more codons otherwise present in the non-mutated mRNA. When there is a deletion of a single codon in the gene for cystic fibrosis, the resultant shorter mRNA codes for a polypeptide chain that does not carry one amino acid. For example, deletion of one codon results in deletion of a Phe residue present at position 508 in CFTR. The mutated transmembrane protein CFTR folds in an improper way.
It is called central vascular catheterization
<h3>Importance of catheterization</h3>
Catheterization is defined as the use of medical devices that can be inserted into the body and used for different medical purposes.
Vascular catheterization is a peripheral catheterization that is used to detect certain upper and lower peripheral extremity conditions.
There are different types of vascular catheterization which include:
- Arteriovenous (AV) fistula,
- Arteriovenous (AV) graft and
- Central venous catheter (CVC)
Central vascular catheterization involves Introducing a vascular catheter directly into a vessel without further advancement past the punctured vessel.

The human skin is the protective layer of the human body against the external forces like the temperature, sharp objects, microbes, fungi and other related materials that can penetrate and weaken the body however, the integumentary system prevents any harm come to the organism. The dermis is the skin area which has different structures that perform different functions.
Answer:
1. During the__ Attachment ____stage, enzymes digest cell wall and membrane material so that the viral nucleic acids can enter into the host cell.
