Which option gives the correct cause-and-effect relationship for Variation and evolution, Cloning (biology only): students must describe adult cell cloning by removing the nucleus from an unfertilised egg cell.

The correct option is Correct cause and effect: A gene is the functional coding section; a chromosome is the larger DNA package. This matches Cloning (biology only) because students must describe adult cell cloning by removing the nucleus from an unfertilised egg cell.. It is the only option that keeps Genes vs chromosomes separate and answers the approved learning objective in Cloning (biology only).

The correct option is Correct cause and effect: A gene is the functional coding section; a chromosome is the larger DNA package. This matches Cloning (biology only) because students must describe adult cell cloning by removing the nucleus from an unfertilised egg cell.. Correct cause and effect: A gene is the functional coding section; a chromosome is the larger DNA package. This matches Cloning (biology only) because students must describe adult cell cloning by removing the nucleus from an unfertilised egg cell. is correct because A gene is the functional coding section; a chromosome is the larger DNA package. The learning objective says students must describe adult cell cloning by removing the nucleus from an unfertilised egg cell, so the answer must stay inside Cloning (biology only). The alternative options are wrong because they either saying a chromosome codes for one protein instead of identifying a gene., using gene and chromosome as the same scale of structure., or drift away from question stems about genes must test coding sections, alleles, or inherited characteristics..
