The genetic code is how we call the combinations of three nucleotides (codons) that cells use to translate the information in the DNA and RNA in proteins.
There are 22 amino acids used to make proteins, but 64 possible codons, so some amino acids correspond to more than one codon. All proteins start with methionine (Met) and there are also codons that mark the end of a protein.
The codon for Met is AUG; and the stop codons are UAA, UAG, and UGA.
This means D is the right answer.

➷ Deforestation can contribute to global warming. Trees take in the carbon dioxide in the atmosphere, therefore, removing these would mean there is more carbon dioxide in the atmosphere. Also, growing certain things can release more greenhouse gases into the atmosphere. For example, rice cultivation releases methane into the atmosphere. Furthermore, growing livestock would increase methane emissions. This would mean the global temperature would increase due to global warming.
b) Permacultures may be used. These mimic natural processes and create sustainable and self - sufficient ecosystems. Another method would be stacking. This is where more things are grown in a given space. The plants would absorb more carbon dioxide from the atmosphere.

Answer:
DNA only.
Explanation:
Both DNA and RNA are built with a sugar backbone, but whereas the sugar in DNA is called deoxyribose, the sugar in RNA is called simply ribose. The ‘deoxy’ prefix denotes that, whilst RNA has two hydroxyl (-OH) groups attached to its carbon backbone, DNA has only one, and has a lone hydrogen atom attached instead.
Answer:
B. Skeletal
Explanation:
The cell wall could be represented as the bones in our body.
