- Chromosomes pass genetic information from one cell to another in cell generation. (j) Explain the relationship between DNA, genes, and chromosomes during the passing of genetic information. (k) During the passing of genetic information from one generation to the next via chromosomes, nondisjunction can occur, interrupting the process. Describe the events that take place during nondisjunction.Describe four different types of chromosomes on the basis of position of centromere.Describe the structure of a chromosome territory.
- Characterize the following human chromosomes as to size and as to position of its centromere. Size Type as to position of its centromere Chromosome In Group C 18 in Group G Y ChromosomeChromosomes that carry the same genes are referred to as what?Name the type of chromosome whose centromere is in middle.
- (a) Explain the relationship between DNA, genes, and chromosomes during the passing of genetic information. (b) During the passing of genetic information from one generation to the next via chromosomes, nondisjunction can occur, interrupting the process. Describe the events that take place during nondisjunction.The following diagram represents two nonhomologous chromosomes: A B • C D E F G R S • T U V W X What type of chromosome mutation would produce of the following groups of chromosomes? Q.A B • T U V F G R S • C D E W XThe microscope image above shows the human chromosomes from a white blood cell. To create the image, researchers put cells in culture under conditions that encourage the cells to divide. They bathed the cells in a hypotonic (low salt) solution, which caused the cells to swell until their plasma membrane burst open. They "squashed" the chromosomes to spread them out, and stained them with a dye to make them visible under the microscope. Human chromosomes are numbered from longest (1) to shortest (22) plus the sex chromosomes X and Y. In the image chromosome 1 is about 7 micrometers. Answer the following questions. 1) What word(s) in the description above indicates that the chromosomes are not from a cell undergoing meiosis? 2) Based on the size, shape and appearance of the chromosomes in the image, in what cell cycle stage was the cell that the chromosomes came from? How can you tell? 3) Does the image suggest that centromere sequences are always located in the middle of a…
