Two ways:
1. In prophase I of meiosis the homologous chromosomes synapse and crossing over occurs. This switches sections of two of the sister chromatids so the outer two chromatids have the same mix of alleles as the parents and the inner two chromatids have new combinations of alleles.
2. Meiosis puts only one of each kind of chromosome in the gametes, selecting one of each homologous pair at random. Then when each gamete joins with the gamete from the other parent, there are practically infinite combinations of the alleles possible.
The correct answer is option A, that is, DNA is photocopied to make RNA.
Transcription refers to the procedure by which DNA is transcribed or copied to make mRNA (messenger RNA) that conducts the information required for the formation of protein. Transcription occurs in two broad stages. First is the formation of pre-messenger RNA, with the application of RNA polymerase enzymes.
The pre-messenger RNA is then amended to generate the desired molecule of mRNA in a procedure known as RNA splicing.
