How is the genetic code similar in early and modern forms of life?

Early forms of life are thought to have used RNA as their sole source of information before DNA existed. The endosymbiotic theory says that millions of years ago a multicellular(eukaryote) organism engulfed a single-celled(prokaryote) organism. Instead of killing the prokaryote, the eukaryote allowed it to remain and incorporated it into its own environment. It is hypothesized that this is the molecular basis for the existence of RNA in eukaryotes.
<span>DNA and RNA differ by one atom. Both eukaryotes and prokaryotes use the same genetic code, and it is repetative in both, to signal the construction of proteins.</span>

6. Which of the following has the lowest cost of production of recombinant proteins?
mina [271]

Answer:

Bacteria

Explanation:

Bacteria constitutes large group of unicellular organisms that lacks membrane bound organelles and constitute cell wall. Bacteria are used for the production of recombinant proteins.

Bacteria can be selected easily for the recombinant protein formation. The plasmid of bacteria is helpful for the integration of desired genes and the production of protein. The bacteria culture can be maintained easily in the laboratory. The different strains of bacteria with different traits can be used for the production of different recombinant proteins at low cost.

Thus, the correct answer is option (1).

Describe the process of speciation. Include in your discussion the factors that may contribute to the maintenance of genetic iso
ivolga24 [154]

Speciation is the process by which new and distinct species are formed. One of the most important factors necessary for speciation to occur is the genetic isolation of two populations. This genetic isolation can, over long periods of time, cause these two groups to become genetically incompatible. Factors that can lead to this genetic isolation include geographic separation and hostility among population groups.
