Study "INGLES", a flashcard deck on FORKSAI.
What is the primary function of a genome? A) To store energy for the cell. B) To provide structural support to the cell. C) To carry all the genetic information of an organism. D) To regulate protein synthesis outside the nucleus.
C) To carry all the genetic information of an organism. The genome contains all the hereditary information of an organism, encoded in DNA (or RNA in some viruses).
Which of the following best describes the location of a genome within a eukaryotic cell? A) Exclusively in the cytoplasm. B) Primarily in the nucleus, with some in mitochondria and chloroplasts. C) Only on the cell membrane. D) Distributed randomly throughout the cell.
B) Primarily in the nucleus, with some in mitochondria and chloroplasts. In eukaryotic cells, the main genome is found in the nucleus, but mitochondria and chloroplasts also have their own small genomes.
What type of molecule typically constitutes the genome in most organisms? A) Protein. B) Lipid. C) DNA. D) Carbohydrate.
C) DNA. The genome in most organisms is made up of deoxyribonucleic acid (DNA), which carries the genetic instructions for development, functioning, growth, and reproduction.
In which cellular structure is the main genome of a prokaryotic cell found? A) Nucleus. B) Mitochondria. C) Cytoplasm (nucleoid region). D) Endoplasmic Reticulum.
C) Cytoplasm (nucleoid region). Prokaryotic cells lack a membrane-bound nucleus, so their genome is typically located in a specific region of the cytoplasm called the nucleoid.
What is the term for a complete set of chromosomes in a cell? A) Proteome. B) Metabolome. C) Genome. D) Transcriptome.
C) Genome. The genome refers to the complete set of genetic material present in an organism or cell.
Which of the following is NOT a component of a typical DNA molecule found in a genome? A) Deoxyribose sugar. B) Phosphate group. C) Uracil base. D) Guanine base.
C) Uracil base. Uracil is a nitrogenous base found in RNA, replacing thymine which is found in DNA.
What is the primary role of genes within the genome? A) To provide structural support to the cell. B) To store excess nutrients. C) To encode for proteins or functional RNA molecules. D) To facilitate cell division.
C) To encode for proteins or functional RNA molecules. Genes are specific sequences within the genome that carry the instructions for building and maintaining an organism.
Which of the following organisms typically has the smallest genome? A) Human. B) Bacteria. C) Plant. D) Fungus.
B) Bacteria. Bacteria generally have much smaller and simpler genomes compared to multicellular eukaryotes like humans, plants, or fungi.
What does the 'G' in DNA stand for? A) Glucose. B) Guanine. C) Genome. D) Glycine.
B) Guanine. Guanine is one of the four nitrogenous bases found in DNA, along with adenine, cytosine, and thymine.
Which of these is a characteristic of a viral genome? A) Always double-stranded DNA. B) Can be DNA or RNA, single or double-stranded. C) Always located in the nucleus. D) Exclusively composed of proteins.
B) Can be DNA or RNA, single or double-stranded. Viral genomes exhibit great diversity, being composed of either DNA or RNA, which can be single-stranded or double-stranded.
