primer

Explanation:

Most biological reactions rely on the enzyme to speed up the reaction. In the case of DNA replication, this enzyme is DNA polymerase. a; DNA is a double helix made up of two long chains of deoxyribonucleotides. ... b; a primer is used to start this process by giving DNA polymerase something to bind the new nucleotide to. just for you to see.

some fungi obtain their nutrients from a living host (plant or animal) and are called most biotrophic fungi have fairly narrow host ranges—they are specialized on a limited called rhizomorphs that allow the fungus to grow from one tree to another. ascospores are formed inside a sac-like structure called an ascus. so your answer is a
