Question
Chapter 15, Problem 1RC
Summary Introduction
To explain: The structure of a bacterial genome and the organization of genetic information in their cells.
Introduction: The entire genetic information of a bacteria is stored in its small genome (130 kbp to 14 Mbp) or genes. These genes are organized into the chromosomes explaining that the entire bacterial genetic information is stored in chromosomes.
Expert Solution & Answer
Explanation of Solution
The genetic material of bacteria is found suspended in the cytoplasm or the nucleoid (nucleus-like region) due to the absence of a nuclear membrane. The bacterial cell consists of a single circular chromosomal DNA and many copies of plasmids (extra-chromosomal circular DNA). But some bacteria also contain multiple and linear circular chromosomes along with the linear plasmids.
Most of the bacterial genetic information is stored in the circular chromosomal DNA, but a small amount of genetic information is also present in bacterial plasmids. These extra-chromosomal circular DNA molecules carry genes coding for various catabolic enzymes, genetic exchange, and resistance to several antibiotics.

You aim to test the hypothesis that the Tbx4 and Tbx5 genes inhibit each other's expression during limb development. With access to chicken embryos and viruses capable of overexpressing Tbx4 and Tbx5, describe an experiment to investigate whether these genes suppress each other's expression in the limb buds. What results would you expect if they do repress each other? What results would you expect if they do not repress each other?
You decide to delete Fgf4 and Fgf8 specifically in the limb bud. Explain why you would not knock out these genes in the entire embryo instead.
You implant an FGF10-coated bead into the anterior flank of a chicken embryo, directly below the level of the wing bud.
What is the phenotype of the resulting ectopic limb?
Briefly describe the expected expression domains of 1) Shh, 2) Tbx4, and 3) Tbx5 in the resulting ectopic limb bud.
