1.) DNA replication is a process where the double helix is unwound and each strand is replicated to create another. This occurs in all replication of the body cells, or reproductive cells, a common process called mitosis.
2) The original DNA molecule is exactly the same as the replicated molecule, but the original is called the parent cell and the replicated molecule the daughter cell.
3) Enzymes act as catalysts/proofreaders of DNA replication. For example, Primase synthesizes RNA primer, or DNA ligase joins DNA strands together.
Cladogram is a diagram that tells the relationships between different groups of taxa called “clades”. Cladogram gives phylogeny (evolutionary history) of the taxa. The organisms which share derived characteristics are grouped together while constructing a cladogram. Jelly fish is a cnidarian share common characteristics such as radial symmetry, simple tissues and no body organs with other members like corals and sea anemones.
Answer:
microfilaments
Explanation:
Cytoskeleton are made of three main filaments including actin filaments, microtubules and microfilaments. Microfilaments are flexible double strands of the protein actin that are of different proteins which give mechanical support. Important functions include:They lead the intracellular movement of organelles and molecules
.They stabilize mechanically the plasma membrane.
