The genetic code defines how codons, sequences of nucleotide triplets, specify which amino acid will be added next during process of translation (protein synthesis).
The genetic code is universal among organisms. That means that the same codons code for the same amino acids in different organisms.
It is known which amino acids are coded by which codons. If we know sequences of amino acids, we then also know sequences of nucleotides in DNA/RNA. If we know DNA/RNA sequences we can then reveal relationships among different organism by compering similarities in those sequences.
B, a nucleus. Nuclei are membrane-bound organelles inside eukaryotic organisms. Eukaryotes are protists, fungi, plants, and animal cells. A bacteria is not a eukaryote, it is a prokaryote, so it does not have the membrane-bound structure of the nucleus.
Be careful, though, bacteria still have DNA. It is simply located in the center of the cell and is not encased in a membrane.
Answer:
It is found in ice/solid form, not liquid or gas
Explanation:
Viruses did not evolve first, they found. Instead, viruses and bacteria both descended from an ancient cellular life form.
Hello! The soil structure has to do with how the soil parts are arranged, but it also has to do with pore space and how it clumps together. Parent material, mineral content, and amount of organic matter ties in with another concept, not really having to do with soil structure. The answer is A.
