Introduction:

Bacteria mostly contain single, circular chromosomes or linear chromosomes with double stranded DNA sequences. Bacterial genome is haploid in nature and ranges between 0.5 to 8 MB in size containing several thousand structural genes which code various proteins for their activities and metabolism.

Expert Solution & Answer

Explanation of Solution

Escherichia coli and Bacillus subtilis are widely used bacterial species with single chromosome, among which E. coli is mostly used, and it has 4.6 million base pairs that encode about 4200 genes. In case of some bacteria, they show two or more chromosomes, e.g. Borrelia burdgorferi, Agrobacterium tumefacian, s and Methanococcus jannaschii. Some bacteria like Borrelia burdgorferi and Agrobacterium tumefacians shows linear chromosome.

Bacterial chromosome has little amount of repetitive DNA sequences in multiple copies at intergenic regions, though they rarely transcribe, they serve a key role in replication, recombination, or in regulation of transcription. In bacterial chromosome, chromosomes are densely packed in a series of tight loops in association with a number of nucleoid associated proteins (NAP), i.e. they show several loops by supercoiling of DNA. There are two types of associated proteins a) small nucleoid-associated proteins and b) structural maintenance of chromosomes proteins (SMC).

Conclusion

All aspects are determined.

If using animals in medical experiments could save human lives, is it ethical to do so? In your answer, apply at least one ethical theory in support of your position.

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.
