In arthropods groups of segments that are fused together into functional groups are called tagmata.
The group of arthropods with a pair of pedipals and no antennae are chelicerata.
One order within this lineage, which has one body segment and pairs of long, spindly legs are the araneae.
# In general arthropods bodies are divided into segments but sometimes their segments are fused to form integrated body parts which are known as tagmata. This fusion process is called tagmosis.
#The chelicerates are characterised by the presence of two tagmata (fused segments), a cephalothorax (fused head and thorax) and an abdomen. They have six pairs of unbranched appendages. These include one pair of chelicerae,one pair of pedipals and four pairs of legs.
# Araneae is an order of arachnida consisting of spiders.

Biologists use gel electrophoresis to sort DNA segments by size. DNA segments are placed at one end of a gel. DNA is negatively charged (with a charge of two electrons per base pair). When you “run the gel” you are generating an electric field by connecting anodes and cathodes at the ends of the gel. This causes the negatively charged DNA segments to move towards the positive electrode. After running the gel, smaller DNA segments have moved farther from the...
