Chapter 5, Problem 2QSDC
Summary Introduction
To review:
The reason behind mitochondria or chloroplast not being taken out of a living eukaryotic cell and being madeto survive on its own.
Introduction:
Mitochondria and chloroplasts were once believed to be primal bacterial cells. Ithas been described in theendosymbiotic theory. Two different species benefitting from living and working together is called symbiosis.

The diagram below represents single-celled
organism A dividing by mitosis to form cells B andC.
B
cکړ
Cells A, B, and C all produced protein X. What can
best be inferred from this observation?
A) The gene to produce protein X was passed from
cell A to cells B and C.
B) Cells A, B, and C ingested food containing the
gene to produce protein X.
C) The gene for protein X is found in single-celled
organisms, only.
D) Protein X is found in all organisms.
Suppose you isolated a mutant strain of yeast that replicates its DNA more than once per cell cycle. In other words, each gene in the genome was replicated several times between successive cell divisions. How might you explain such a phenomenon?
Why do eukaryotic cells need to go through the elaborate procedure of mitosis rather than simply dividing during interphase? Select as many answers as apply.
1.Daughter cells must be genetically identical to the mother cell, for homeostasis and ordered tissue growth.
2.Bivalent chromosomes must condense and be separated in an orderly fashion, to allow equal distribution of copies into daughter cells
3.Physically dividing the nucleus during interphase would likely lead to gross chromosome breakage and highly unequal assortment of genetic information into daughter cells.
4.Dividing the nucleus during interphase would have the same outcome as mitosis
5.Daughter cells must have half the number of chromosomes after mitosis than the mother cells
6.The homologous pairs of chromosomes need to be separated, to ensure copies go to the daughter cells.

- Give typing answer with explanation and conclusion to all parts The chromosomes drawn below are found in a human skin cell. The lines represent the chromosomes themselves. The letters indicate the location of a particular version of a gene. a) T/F An individual’s offspring are more likely to inherit a D1 and R together than a D1 and T9 together. b) T/F About 50% of the egg cells from this individual will have both T9 and BA5. c) T/F Because r is recessive, the frequency at which the r version of the gene occurs in a population is lower than the frequency at which the R version occurs in the population. d) T/F If the protein produced by the BA gene is involved in the formation of ovaries, then the BA gene is likely located on a sex chromosome. e) T/F Because the genes shown here are found in skin cells, these genes code for proteins required for skin cell function.arrow_forwardHomologous chromosomes a) are formed when the chromosomes separated during anaphase b) are matching set of chromosomes that a cell receives from both parents c) carry the same alleles in the same sequence d) are a set of identical alleles that a cell receives from both parentsarrow_forwardHumans have 46 pairs of chromosomes while chimpanzees have 48 pairs.
