Every cell contains a DNA "cookbook" that provides directions on how to make and maintain that cell When a cell reproduces, it must duplicate its DNA, providing one copy to the new offspring cell while keeping one copy for itself Wafton and Crick realized that the chemical properties of each kind of base in DNA dictated the base pairings Each base has protruding chemical groups that can best form hydrogen bonds with only one appropriate partner Besides having practical purposes, a shared genetic vocabulary also reminds us of the kinship that connects all life on Earth The process of DNA replication requires the cooperation of more than a dozen enzymes and other proteins

Cells contain genetic information Which of the following sentences describes how genetic information is organized and used? O Genes in DNA molecules encode directions for chromosomes: O Chromosomes are organized into strands of RNA O Genes in DNA molecules encode directions for protein production A single gene is composed of multiple chromosomes
Check the box under each molecule for which the statement in the first column is true. statement It communicates genetic information from the chromosomes to the cellular "factories" responsible for synthesizing new proteins. It does not contain instructions for making a protein. It usually contains several hundred amino acid resides. It's made in the nucleus, but transported to the cytoplasm to do its job. When combined with a number of different proteins, it forms a large complex in the cytoplasm responsible for synthesizing new proteins. ribosomal RNA 0 transfer messenger RNA RNA n [] 0
Suppose you carry out genomic, transcriptomic, and proteomicstudies on a single tissue. What type of information would youobtain from each sort of study? For understanding physiology,what are the uses and shortcomings of each type of information?
Background: DNA nucleotides (i.e A, T, G, and C) are naturally found in a paired, or bonded, arrangement (i.e. the double helix) within the nucleus of every cell. This structure makes the process of replication that occurs prior to mitosis and meiosis very reliable. The purpose of DNA, though, is not simply to make copies of itself, but to provide a set of instructions for the synthesis or "construction" of biomolecules, such as proteins. Why is transcription (i.e. the formation of an RNA copy of a given gene) a necessary step in the "construction" process highlighted above? What is the cell looking to ultimately do with this RNA information?

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.
Name the three major assumptions made by the "Cell theory". (i) The lipid membrane is composed of lipid molecules. Explain the principle of membrane formation highlighting the role of the physical properties of the lipids. (ii) Comparing dimensions and length scales is often a first step in an analysis. Give an approximate value for the thickness of a lipid bilayer and the linear length of a helical turn of a DNA double helix.
