Which of the following statements about DNA are true? (choose all that apply) O It is a polymer composed of nucleic acids It is often found as a small molecule combined with cell surface proteins and lipids and serves as a kind of name tag identifying "self" to distinguish it from "nonselt it is a polymer composed of carbohydrates, and is one of the molecular building blocks of cell wall. O DNA is the molecule that stores the genetic information. in eukaryotes, it is primarily found in the nucleus, a membrane-bound structure that contains the metabolic and chemical processes of gene expression and MRNA transcription. O it is a polymer composed of amino acids, and is one of the important subunits in cell membranes. in prokaryotes, it is found in the nucleoid region, but prokaryotes don't have a membrane-bound nucleus.

Guanine, cytosine, thymine, and __________________ are the four __________________ in DNA. In DNA, guanine always forms hydrogen bonds with __________________. The process of __________________ produces a new copy of an organism’s genetic information, which is passed on to a new cell. The double coiled, “staircase” shape of DNA is called a __________________.
Which is NOT a true difference between messenger RNA and DNA? (i.e., which of the following statements is false?) DNA remains in the nucleus (except when the nuclear envelope breaks down during mitosis), whereas mRNA is never in the nucleus; it is always in the cytoplasm. A DNA molecule has a longer life span than a typical molecule of RNA. DNA has thousands of genes; mRNA is usually a copy of just one gene. DNA has thousands of genes; mRNA is usually a copy of just one gene.

DNA and RNA are both nucleic acids, but their structures and functions differ. Which of the following options correctly describes the structures and functions of DNA and RNA? a RNA is made from DNA and is used in transcription, while DNA is used in translation. b DNA is a double helix that is used to make proteins, while RNA is single-stranded and used to make lipids. c In DNA, adenine, thymine, guanine, and cytosine join together and carry all of the genetic information.
