What is DNA? 1. Instructions for providing information for a living organism to grow and reside in a cell are called 2. Where is the nucleus located? 3. Encoding a detailed set of plans for building parts of the celli is called 4. DNA stands for 5. A always pairs with _ and \( \mathrm{C} \) always pairs with - . What is a gene? 1. The instruction manuals for our bodies are called 2. Of the genes in the body only a few are used for making hemoglobin. 3. Since genes contain instructions for building proteins, one example of a protein would be Whot is a chromosome? 1. How much DNA is in a single human cell? 2. When the sperm and egg cells join, they form a cell. 3. Each child born to a set of parents has a combination of chromosomes. What is a trait? 1. A is a notable feature or quality in a person. 2. traits are characteristics of one's physical make-up or appearance. 3. traits are characteristics of the way one acts. 4. An increased risk of getting a certain type of disease is called 5. The set of genetic information form for each characteristic is called a/an 6. describes two of the same allele for a trait. 7. describes having two different alleles for a trait.

Which of the following best describes a biological concern regarding the use of CRISPR-Cas9 gene editing in humans? A. The process was first discovered in bacteria and human cells cannot correctly interpret prokaryotic regulatory signals. B. The modifications created by the process may result in unintended effects on non-target genes. C. The presence of repeated sequences (STRs) within the human genome means that the editing cannot be targeted to a specific location. D. The process may introduce viral sequences into the human genome leading to unwanted blood cell proliferation (leukemia). 2. A person is heterozygous for a locus on Chromosome 1. The first copy of Chromosome 1 has the sequence 5'-AACTACGA-3'; the second copy has the sequence 5'-AACTTCGA-3'. Which of the following statements correctly describes these sequences? A. They may carry out RNA interference. B. They contain an STR that may be useful for forensic analysis. C. They contain a SNP that may be useful for genetic mapping. D. They identify a location where only one copy could be cut by a restriction enzyme. 3. Use the following information to answer the question. A piece of DNA was incubated with a restriction enzyme called Hind III. The restriction enzyme digestion produced eight different size fragments that were separated by gel electrophoresis. Which of the following observations correctly describes characteristics of the outcomes of this process? A. When separated by gel electrophoresis, the pattern of DNA bands specific to Hind III digestion; repeating the process using a different restriction enzyme would not produce these fragments. B. If an electrical current is not used during gel electrophoresis, eight separate DNA bands would be visible, but they would not be separated as much as when an electrical current is used. C. The sequence that Hind III binds is found at places in this piece of DNA; gel electrophoresis provides the force needed to break the DNA under the DNA-enzyme complexes. D. Because restriction enzymes cut specific sequences of DNA, use of any other different restriction enzyme would result in one large piece of DNA rather than eight fragments.

A. A diploid cell containing 26 chromosomes undergoes mitosis B. A diploid cell containing 34 chromosomes undergoes meiosis C. A diploid cell containing 28 chromosomes undergoes meiosis D. A diploid cell containing 22 chromosomes undergoes mitosis TRUE or FALSE: The nuclear envelope (nucleus) must remain intact throughout mitosis. A true-breeding narrow petal flower is mated to a true-breeding wide petal flower and all of the F1 offspring have wide petals.
