ransfer RNA in eukaryotic cells is synthesized by which of the following enzymes (sensitive to high concentrations of the fungal poison a-amanitin, but not to low concentrations)? RNA polymerase I DNA polymerase I RNA polymerase II DNA polymerase II RNA polymerase III
DNA and RNA
Deoxyribonucleic acid (DNA) is usually called the blueprint of life. Deoxyribose is a monosaccharide that has a key function in the synthesis of deoxyribonucleic acid. One less oxygen-containing hydroxyl group occurs in deoxyribose sugar. Nucleic acid, deoxyribonucleic acid, is one of the natural components. Deoxyribonucleic acid is a double-stranded molecule. Watson and Crick postulated the double-stranded model of the helix. A deoxyribonucleic acid is a molecular group that carries and transmits genetic information from parents to offspring. All eukaryotic and prokaryotic cells are involved.
DNA as the Genetic Material
DNA, or deoxyribonucleic acid, is a long polymeric nucleic acid molecule discovered in the late 1930s. It is a polymer; a long chain-like molecule made up of several monomers connected in a sequence. It possesses certain characteristics that qualify it as a genetic component. Certain organisms have different types of nucleic acids as their genetic material - DNA or RNA.
Genetics
The significant branch in science which involves the study of genes, gene variations, and the organism's heredity is known as genetics. It is also used to study the involvement of a gene or set of genes in the health of an individual and how it prevents several diseases in a human being. Thus, genetics also creates an understanding of various medical conditions.
DNA Replication
The mechanism by which deoxyribonucleic acid (DNA) is capable of producing an exact copy of its own is defined as DNA replication. The DNA molecules utilize a semiconservative method for replication.

Which of the following processes of genetic information flow can occur under laboratory conditions, but has never been observed to occur under natural conditions (either in living cells or in viruses)?
- transcription of RNA from a DNA template (using DNA-dependent-RNA-polymerase)
- self-replication of RNA from an RNA template (using RNA-dependent-RNA-polymerase)
- direct-translation of protein from a DNA template (using special ribosomes)
- self-replication of DNA from a DNA template (using DNA-dependent-DNA-polymerase)
- translation of protein from an RNA template (using ordinary ribosomes)
α-amanitin is a cyclic octapeptide that contains several modified amino acids.
