Question

a typical prokaryotic has about 3000 genes in its DNA, while a human cell has about 20500 genes. About 1000 of these genes are present in both types of cells. explain how such a different organisms could have the same subset of genes. What sort of functions might these shared genes have? Justify

Answer 1

Central dogma

Step-by-step explanation:

The answer can be explained according to central dogma, in molcular cell biology. Prokaryotes and eukaryotes, both have the basic materials required for protein synthesis. Prokaryotes are able synthesise and modify proteins, despite lacking the complex organelle structure that eukaryotes have. Eukaryotes structures have evolved into separated and membrane bound organelles. However, because prokaryotes and eukaryotes share basic genetic componants, the following processes can occur: replication, recombination, modification and mutation.
