Can someone explain the process of RNA editing?

Talja [164]

The process of RNA editing is the alteration of the sequence of nucleotides in the RNA after it has been transcribed from DNA, but before it is translated into a protein. RNA editing occurs by two distinct mechanisms:Substitution editing and Insertion/deletion editing.

Substitution editing is the chemical alteration of individual nucleotides. These alterations are catalyzed by enzymes that recognize a specific target sequence of nucleotides:

*Cytidine Deaminases that convert a C in the RNA to uracil.

*adenosine deaminases that convert an A to inosine,which the ribosome translates as a G.Thus a CAG codon (for Gln) can be converted to a CGG codon (for Arg).

*Insertion/deletion editing is the insertion or deletion of nucleotides in an RNA.

These alterations are mediated by guide RNA molecules that base-pair as best they can with the RNA to be edited and serve as a template for the addition( or removal) in the target.

Using the key choices, identify each type of cartilage described (in terms of its body location or function) below.

Umnica [9.8K]

Answer:

elastic 1. supports the external ear

fibrocartilage 2. between the vertebrae

hyaline 3. forms the walls of the voice box (larynx)

elastic 4. the epiglottis

hyaline 5. articular cartilages

fibrocartilage 6. meniscus in a knee joint

hyaline 7. connects the ribs to the sternum

fibrocartilage 8. most effective at resisting compression

elastic 9. most springy and flexible

hyaline 10. most abundant

Explanation:

Cartilage is a type of connective tissue that is characterized by being avascular and very flexible. There are three types of cartilages that can be differentiated by their histological properties, their function and their specific location in the body.

Hyaline cartilage is the most abundant and can be commonly found in articulations.

Fibrocartilage presents a mix of cartilage tissue and collagen fibers, making it tougher than the other types.

Elastic cartilage is much more flexible because it has elastic fibers and is found in places where this flexibility is needed (like the epiglottis).

Which two strata of the epidermis are most susceptible to cancer?

strojnjashka [21]

Answer:

The correct answer is - strata spinosum and strata basale.

Explanation:

The two strata of epidermis that are prone to the cancer are stratum basale and stratum spinosum. The stratum basale is the major stratum layer as it is only layer that can divide and mitotically active.

The other major layer that is succeptible to cancer is spinosum as it allows the maturation of the keratinocytes. The major culprit is UV light, however other causes such as radiation and arsenic can also cause cancer.

Thus, the correct answer is - strata spinosum and strata basale.
