Question
Chapter 13.2, Problem 3CC
Summary Introduction
To analyze:
The analogy between shoes with haploid and diploid human chromosomes.
Introduction:
Human life starts with a single-cell zygote. The zygote is a diploid cell containing one chromosome from each parent. Through the process of mitosis, the cell divides and transmits the genetic information from one generation to next.

Consider the following DNA molecule (shown in the picture) and assume this is the DNA sequence of the entire chromosomes.
list the amino acid sequences of the possible protein or proteins that could be produced from this DNA sequence
what would be the DNA sequence of a sister chromatid generated from this chromosome sequence? (specify the 5' nd 3' ends)
A prairie grass species called "little bluestem" is tetraploid. It has four complete sets of chromosomes. There are ten kinds of chromosomes; in other words, each complete set of chromosomes has a total of 10 chromosomes. A single somatic cell (e.g., a cell in a leaf) will have 40 chromosomes, 4 of each kind of chromsome, i.e., 4 of the number 1 chromsome, 4 of the number 2 chromsome, etc. The illustration below shows prophase of meiosis 1 in chromosome number 10. In a diploid cell, there would be one tetrad (group of 4 chromatids) for each kind of chromosome. For example, there would be one tetrad for chromosome 8, one for chromsome 9, etc. When the tetraploid little bluestem undergoes meiosis, how many of chromosome number 10 will each sperm cell carry?
In an electrophoretic gel across which is applied a powerful electrical alternating pulsed field, the DNA of the haploid fungus Neurospora crassa (n = 7) moves slowly but eventually forms seven bands, which represent DNA fractions that are of different sizes and hence have moved at different speeds. These bands are presumed to be the seven chromosomes. How would you show which band corresponds to which chromosome?

- ● ● Illustrate the chromosome changes in interphase and mitosis using a diploid cell that is 2n=4 (two large and two small chromosomes). Label the circles as G1 and G2 stages of interphase and each phase of mitosis (in order). Draw the chromosome in each circle using the following guidelines. 1) For unreplicated chromosome draw a line (/) and for replicated chromosome draw an X. 2) For simplicity, do not indicate that the chromosomes are decondensed chromatin during interphase. 3) Skip drawing the nuclear membrane or spindle fibers, since we are focusing on the chromosomes. Label genes in the resulting daughter cells as A/a and B/b. (These letters represent genes which are at particular places along the DNA molecule. Each chromosomes can have a thousand genes but we are focusing on these two.)

Be sure to label each chromosome (I, II, III, or IV) and include the following in your drawing: centrosomes, 3 kinds of microtubules, metaphase/equatorial plate, and plasma membrane. Use the letter p to indicate a paternal chromosome and m to indicate a maternal chromosome.arrow_forwardMitotic nondisjunction can occur, particularly in tumor cells.

Next, consider the daughter cell with the larger number of chromosomes: How many total chromosomes will this cell have? How many X chromosomes will this cell have?arrow_forward
