please help me in 2 or 3 minutes A genome is best defined as . A. the portion of our DNA that codes for proteins B. all the DNA found in our cells C. a map of a chromosome D. the noncoding portion of our DNA

C. a map of a chromosome

Explanation:

In the fields of molecular biology and genetics, a genome is the genetic material of an organism. It consists of DNA. The genome includes both the genes and the noncoding DNA, as well as mitochondrial DNA and chloroplast DNA.

Hope it helps.

identify the dna change shown in the diagram and explain how that change can result in the increased genetic diversity often seen among siblings.

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.
