<span>The answer is
transcription. It is mediated by RNA polymerase enzyme
that reads the DNA template and makes an RNA
strand that is antiparallel and composed of nucleotides complementary to the DNA strand. This process is the first step of
gene expression. </span>
Ans.
Animals are multicellular, eukaryotic organisms that belong to domain eukarya. They have cells with membrane-bound cell organelles, such as mitochondria, endoplasmic reticulum, nucleus, Golgi body, and lysosomes. In these organisms, genetic material is present inside the nucleus (known as true nucleus), which is surrounded by double-membrane system.
Thus, the correct options are:
-They contain a nucleus.
-They are eukaryotic.
-They contain membrane-bound organelles.
