1. What are the characteristics of the homeo box found in the homeo gene?
① It is a type of proto-oncogene commonly found in breast cancer.
② It promotes cancer by increasing the rate of cell division.
③ It is a characteristic gene that appears only in mammals and birds.
④ It is found only in the source of recent evolution, and encodes the animal species that has undergone recent differentiation.
⑤ Although found in a variety of organisms, they are very similar and are considered a common heritage of evolution.
2. How does DNA packing affect gene expression?
① By controlling access to DNA
② By locating related genes nearby
③ By protecting DNA from mutation
④ By promoting gene recombination
⑤ by allowing unpacking to remove genes from the genome
3. Which of the following statements about the Human genome project is correct?
① Started in 1990 and stopped in 2003 due to ethical and legal issues.
② The U.S. Department of Energy, Europe, and all countries participated and were able to complete the project in a short time.
③ Only 2% of the functions of 25,000 genes were revealed through HGP.
④ All genes have a genetic code for protein synthesis.
⑤ Interpret all nucleotide sequences of the human genome
4. Which of the following statements about the Post-genome project is incorrect?
① Research on which bases function to make a specific protein
② Research that interprets and makes available DNA sequences
③ Identification of how individual nucleotide sequences differ
④ Proteome research that reveals the structure of proteins
⑤ Development of various technologies such as DNA chips
5. Why do bone cells, muscle cells, and skin cells look different?
① Because each cell has different types of genes.
② Because these cells exist in different organs.
③ Because different genes are activated in different types of cells.
④ because the number of genes they have is different
⑤ Because each cell has different types of mutations.
6. Which of the following statements is incorrect?
① The ras gene is a gene that participates in cell migration.
② Cancer occurs due to a problem in the regulatory mechanism that limits cell division.
③ In humans, 13 kinds of homeo genes work to form segments and make individual components.
④ Genetic information is a long enough nucleotide sequence, and a difference of one or two nucleotides does not affect it.
⑤ The key to unlocking the blueprint of the human body is the protein created by the genes.
7. What are some examples of life forms on Earth showing the same diversity and ability to adapt to the environment through repeated mutations?
① Mutation of the gene on chromosome 11 that turns red blood cells into sickle shape
② Mutation of chromosome 11 gene involved in atopic dermatitis.
③ A gene mutation on chromosome 8 that preserves fat accumulated in the body.
④ Mutations in genes that make chemokine receptors.
⑤ All answers are correct.
8. Which of the following statements about the cancer suppressor gene p53 is correct?
① The P53 gene plays an important role in cell division by producing a strong growth-promoting protein.
② Abnormal regulation of cell division with proto-oncogenes.
③ If there is a risk of cancer cells because the cells cannot be repaired, it plays a role in cell death.
④ It is called an anticancer gene because it exists only in cancer cells rather than in normal cells.
⑤ As a tumor-suppressor gene, it is not a proto-oncogene.
9. Which of the following statements about adenovirus is incorrect?
① It proliferates in the nucleus and contains DNA, so it integrates into the host chromosome and self-renews, so it is used as a virus carrier (vector).
② In humans, it invades the mucous membrane of the eye or the lymph nodes, causing pharyngeal conjunctival fever and epidemic keratoconjunctivitis.
③ Because each host is specific, it is generally not infected with other animals.
④ It is used in gene therapy to treat cancer by genetically changing it.
⑤ All correct answers
10. Which of the following is true for the use of microarrays (DNA chips)?
① By measuring the level of alpha-fetoprotein (AFP), genetic diseases such as Down syndrome can be determined in advance.
② The length of the STR sequence in a specific region of the organism can be compared.
③ Due to the limited space, it is not possible to show gene expression patterns throughout an individual's lifetime.
④ It is possible to know which genes are activated (transcribed) in a specific cell.
⑤ All correct answers
① It is a type of proto-oncogene commonly found in breast cancer.
