Answer:
The creation of the limbs is carried out by AER and ZVP. AER stands for apical ectodermal ridge and ZVP stands for polarising activity line.
Explanation:
- AER is responsible for the developmental progression in the distal to the anterior region and the ZVP is liable for the progressive advancement in the posterior to a backward region.
- AER and ZVP are interconnected on one another in the secretion of a sonic hedgehog, which eventually assists throughout the hox speech to promote the growth of the arm.
- The hypothesis that the new short-arm gene inhibits the effect of FGF (fibroblast growth factors) on AER can be tested and use a template of cultured cells.
- The AER may be disrupted in the model and the impact of the gene encoding on FGFs may be examined. If in the existence of a viral vector, the role of the FGFs is to trigger correct growth, then the hypothesis is incorrect, or else the hypothesis is right. The FGF8 is by far the most powerful of all as the result.
Which of the following men? Need the men’s blood type
Answer:
D) A and B
Explanation:
DNA molecule replication, also known as duplication or polymerization, is a genetic phenomenon that ensures self-duplication of information contained in chromosomes, specifically in genes.
DNA replication is semi-conservative, each strand serves as a template for the construction of a new molecule. This process allows genetic information (nucleotide sequence) to be copied extremely simply and efficiently. Moreover, replication is bidirectional, that is, it occurs in both strands of DNA at the same time through a replication "bubble" with two forks that move in opposite directions.
Explanation:
Hurricanes form over the warm ocean water of the tropics. When warm moist air over the water rises, it is replaced by cooler air. The cooler air will then warm and start to rise. This cycle causes huge storm clouds to form.
