Elements are made from one type of matter.
Explanation:
1) The enzyme helicase catalyses the unwinding of the two DNA strands by disrupting the hydrogen bonds between complementary base pairs.
2) Single-stranded binding proteins attach to the DNA strands to stabilise them and prevent them from joining back together.
3) The enzyme primase catalyses the addition of a short primer consisting of RNA nulceotides to the DNA strand. This serves as an 'anchor' DNA polymerase to initiate replication.
4) The enzyme DNA polymerase synthesizes a new DNA strand by incorporating DNA nucleotides complementary to the existing strand. DNA polymerase activity only occurs in the 5' ---> 3' direction.
5) The enzyme ligase catalyses the formation of hydrogen bonds between the two new pairs of DNA strands, and seals any breakages in the sugar-phosphate backbone.
Eustatic changes are changes in the Ocean which change the global sea level. That is a huge amount of water. Whats something that could generate that much water when melted? (Hint: Global Warming)
Answer:
Explanation: Ependymal cell is a type of neuronal support cell the forms the epithelial lining of the brain ventricles in the brain and the central canal of the spinal cord ependymal cells similar to all other neuroglia, are derived from a layer of embryonic tissue known as neuroectoderm.
