The key features of a cell.

Introduction:

Cells are the smallest unit of life.

Expert Solution & Answer

Explanation of Solution

Cells are what make up all forms of life in the world. They are the smallest unit of life that can exist independently and carry out all the biochemical processes that sustain life.

A cell is made up of genetic material consisting of Deoxyribonucleic Acid or DNA, and a jelly like substance called cytoplasm consisting of water, salts, and other chemicals. These are enclosed inside a cell membrane.

Cells arise only from preexisting cells.

Conclusion

The key features of a cell are

They are the smallest unit of life that can live independently.
All forms of life are made of one or more cells.
Cells arise only from preexisting cells.

Students have asked these similar questions

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.
