It’s either the first 2 but I’m leaning towards the first answer
<span>There are three basic chemical components of DNA - 1. Four "Nucleic acids", 2. Deoxyribose sugar, and 3. Phosphate backbone. The overall shape of the molecule is a double-stranded, double helix. It looks a bit like a spiral staircase wrapped around a spiral staircase. Phosphate groups outside, nucleic acids inside the helix,</span>
The nucleus, which disappeared at the beginning comes back, including the general organelles like Cytoplasm and cell membrane, the DNA also turns back into long strains of DNA, the chromosome go.
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.
