DNA does all but which of the following?
siniylev [52]

Answer:

The correct answer will be option-is read by ribosomes during the process of translation.

Explanation:

The DNA is a nucleic acid made up of nucleotides which serves as a genetic material of the cell. It stores the information required by the cell in the form of codons made up of nitrogenous bases. The DNA after transcription forms a messenger molecule called mRNA which is read by the ribosomes to code for specific amino acid which binds to form the proteins, the building block of the body.  

Since the mRNA is read by the ribosomes during translation and not DNA directly, therefore, the selected option is the correct answer.

Imagine a scenario where a disease has infected many species of grass in the savanna. How would this situation affect the animal
Thepotemich [5.8K]

Answer:

The effect that a situation like this:

Imagine a scenario where a disease has infected many species of grass in the savanna.

Would have in is A disbalance in the ecosystem because the infected plants would die and they won't be able to feed the animals that eat them and they would have to migrate to look for plants to eat. That would also lead to predators that eat the animals that feed on plants to follow them and both types of animals would be reduced in the trip.

Explanation:

To understand this answer we need to analyze the full context. First of all the plants are used as food by the herbivores, therefore they would see themselves in the need to look for healthy plants that could be used as food. Predators would follow them and this trip will reduce the number of both because they would require energy and food to keep traveling. The herbivores would take the worse part because they are bigger in number and their food would scarce, while they would be used as easy food for the carnivores.
