Two types of núcleos acid are

Explanation:

first it is nucleic not núcleos if u want nucleic

then The two main types of nucleic acids are deoxyribonucleic acid (DNA) and ribonucleic acid (RNA).

prophase: we can observe the chromosomes to coil up and condense. they become visible. nuclear membrane and envelope disintigrate.s

metaphase: chromosomes align at the center, the metaphase plate. spindle fibers attach to centromeres of the sister chromatids. they meet at kinetochores.

anaphase: sister chromatids are pulled towards each opposing centromere, set on different poles.

telophase: chromosomes are now clustered up only on either sides of the cell. nuclear membranes reform, and a new cell wall forms along the cell plate. this will lead to cytokinesis, the process that divides the cell membrane and forms the cell wall.

a covalent bond, specfically triple bond
