The AUC and AUA codons in mRNA both specify isoleucine. What feature of the genetic code explains this?

Biology
1 answer:
Serjik [45]2 years ago

Answer:

Degeneracy

Explanation:

  • There are 4 nucleotide  bases and they can form a lot of different codons -  about 64 different codons
  • There are only 20/21 amino acids, not enough for each of the codons

As a result, codons have to "double up" and share amino acids because there is only a limited number of these that they can code for

How does the enthalpy of photosynthesis compare to the enthalpy of cellular respiration?
Dovator [93]

Cellular respiration associates oxygen with glucose within the mitochondria to generate ATP; water and carbon dioxide are generated as well. Photosynthesis utilizes energy from sunlight to produce glucose and distinct oxygen from carbon dioxide and water.

The cellular respiration uses the outcomes of photosynthesis and photosynthesis utilizes the outcomes of cellular respiration at its initial stage.

Both the process of cellular respiration and photosynthesis exhibit an equal enthalpy. Thus, the correct answer is option A.

Describe the importance of biomes such as forests, freshwater, and marine biomes? How have human actions affected these biomes?
Artemon [7]

Answer:

Forest biome:  It gives us medicinal plants, woods for commercial purpose. Forests provides us rubber and fibers that is very important for the industries for making various products. They also contribute to perform ecological  functions such as carbon storage, nutrient cycling, water and air purification. It also provides habitat to the wildlife.

Freshwater biome:  We use fresh water for drinking water, irrigation, sanitation systems, and in industrial factories. Water used from groundwater, rivers and lakes is regained by rain and snowfall.

Marine biome:  It serves huge amount of oxygen into the environment and absorbs the atmospheric carbon dioxide.

As a result of the activity of human there is a significant decrease in the number of trees. The products now used are synthetically made which were made up of natural fibers previously. The water source such as rivers, lakes, and ponds are polluted due to which many water borne diseases are increasing day by day. The accumulation of waste which are found in marine biome are reducing the number of flora present inside marine ecosystem.
