9. EVOLUTION CONNECTION A typical prokaryotic cell has about 3,000 genes in its DNA, while a human cell has almost 21,000 genes. About 1,000 of these genes are present in both types of cells. Based on your understanding of evolution, explain how such different organisms could have this same subset of 1,000 genes. What sorts of functions might these shared genes have?

Answer #1

any DNA found in common with other primate is an evidence of common ancestory.these genes are fundamental to all biological life as we know it .these would be the things like DNA polymerase ,RNA polymerase, enzymes,for the pathways for making the amino acids and lipids and glucose ,nucleootides,ppathways for breaking molecules to get energy,and other functions which are performed in all organisms

    A cell's genome is its blueprint for life. However, what is the bare minimum number of genes needed to sustain a free-living cell? This is a question that microbiologists at the J. Craig Venter Institute (JCVI) have attempted to answer ever since they sequenced the genomes of several Mycoplasma species in the 1990s. Because Mycoplasma species are parasitic bacteria, their genomes are already reduced in size and hence provide an excellent foundation for creating a "minimal cell." However, little did...

    can help me writing a summary please Chromosomal Aberrations and Human Disorders In addition to mutations that alter the information content of a single gene, chromosomes may be subjected to more extensive alterations that occur most commonly during cell division. Pieces of a chromosome may be lost or segments may be exchanged between different chromosomes. Because these chromosomal aberrations follow chromosomal breakage, their incidence is increased by exposure to agents that damage DNA, such as viral infection, X‐rays, or reactive...
