Asthma is a chronic disease of the lung that has been increasing at an alarming rate in industrialized countries around the world over the last few decades. Although considerable progress has been made in our understanding of the underlying pathogenesis of the disease, the exact causes of the increasing prevalence are unknown. Studies suggest that most asthma develops in early childhood and that environmental factors present early in life may be crucial in the development of disease. One potential explanation for the recent epidemic referred to as the "hygiene hypothesis" postulates that factors that have resulted in a reduction in exposure to microbial products and/or infections in the western world may be contributing to this rise in disease prevalence. As early life influences are known to play an important role in establishment of asthma, studies have focused on the interface between mother and child that occurs during gestation and through breastfeeding. In this regard, the body of evidence regarding the relationship between breastfeeding and asthma indicates benefit but with the potential for risk. While providing population-level protection from infections and atopy in infancy and early childhood, breastfeeding might also pose an increased risk of atopic asthma among children with asthmatic mothers.
Answer:
The provided events can be classified as:
Initiation
- In prokaryotes, the Shine-Dalgarno sequence pairs with rRNA.
- In E. coli, mRNA binds to the 30S ribosomal subunit.
Elongation
- In E. coli, EF-Tu delivers an aminoacyl-tRNA to the ribosome
- Initiator tRNA enters the P site.
- In E. coli, EF-Tu hydrolyzes.
- Translocation occurs
Termination
- The ribosome has mRNA, an empty A site, and deacylated tRNA in the P site
Translation is the process by which polypeptide chain is synthesized based on the codon sequence of the mRNA (messenger ribonucleic acid).
It is divided into three stages:
Initiation: The small and large sub-units of the ribosome get assembled around the initiation codon. It forms three sites (A, P, and E site) for interaction tRNA and mRNA.
Elongation: Specific charged-tRNA enters from A site and transfers its amino acid to the growing polypeptide chain in P site. Uncharged tRNA exit from the E site. Ribosome moves or translocates to the next codon.
Termination: As soon as ribosome reaches the termination codon, it releases the newly synthesized polypeptide chain.
C extinction because they need diversity to reproduce
Answer:
I think its A. Valley Formations !
Explanation:
I apolgize if i'm wrong
Answer:The last minor reason there are no basements in the south has to do with the frost line. For a building to maintain strength, its foundation should be below the frost line in the soil. ... There is no reason for builders in the south to build a basement because the foundation doesn't need to be very deep anyway.
