Answer:
The centromere is an undivided structure of DNA.
Explanation:
Chromosomes attached to the mitotic spindle via structures called the centromere. The centromere is an undivided structure of DNA. Once the spindle fibers attached, they're able to position the chromosomes for cell division
Answer:
these biomes has permanently frozen water in its soil is a tundra.
In order to create an exosomes miRNA panel for predicting recurrence after surgery in patients with PDAC, we undertook genome-wide expression profiling.
Offering patients with pancreatic ductal adenocarcinoma (PDAC) personalized therapy requires pre-treatment risk classification, yet it is still difficult to predict recurrence after surgery.
plasma and serum samples from four cohorts of PDAC patients were examined. We carried out genome-wide sequencing on a discovery cohort (n =
) to find potential exosomes miRNAs (exo-miRNAs). Then, using two clinical cohorts without neoadjuvant therapy (NAT) (training cohort:
validation cohort:
) and a post-NAT clinical cohort (n =
, we trained and validated the exo-miRNAs' predictive performance.

Condensation stage of storm formation is when a convection cell is created
Explanation:
When warm and moist air rises into the cold air that is called thunderstorm. Due to moisture that warm air becomes cooler. We all called it water vapor. It forms small water droplet and this process is understood as condensation.
The cooling of air drops which is lower in the atmosphere which becomes warm and rises again and rising and falling circuit is known as convection cell. Rising and falling is responsible of cloud formation
