There are 4 nitrogenous bases in DNA. Adenine pairs with thymine, and Guanine pairs with cytosine. A Dna Nucleotide consists of a 5 carbon sugar, a phosphate group and a nitrogenous base. These bases are paired up by weak hydrogen bonds, so when they have have to replicate, the enzyme helicase can easily unzip the Dna. <span />
The initiation of DNA replication occurs in two steps. First, a so-called initiator protein unwinds a short stretch of the DNA double helix. Then, a protein known as helicase attaches to and breaks apart the hydrogen bonds between the bases on the DNA strands, thereby pulling apart the two strands.
So yeah xD

Answer:
Fungi
Explanation:
Fungi is a eukaryotic organism that is re-evaluating its position in the tree of life.
Fungi are closely related to the animal kingdom in comparison to the plant kingdom. Because of the presence of the chitin in their cell walls, fungi is different from plant, bacteria, and protists. But fungi have cell wall while animal cells do not contain cell wall, so not classified as animals.
So, fungi is re-evaluating its position in the tree of life and in present there is a individual kingdom for fungi.
Answer:
Hair evidence is considered "class" evidence because the hair can be connected to a certain group.

The other reason is that may be the hair has been dropped by the real thieves in order to be caught the John Doe in the crime. Hair evidence is considered "class" evidence because the hair can be connected to a certain group.
