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.
Answer:
The proton–proton chain, also commonly referred to as the p–p chain, is one of two known sets of nuclear fusion reactions by which stars convert hydrogen to helium.
Answer:
What is an allele.one of two or more alternative forms of a gene that arise by mutation and are found at the same place on a chromosome.
Explanation:
The main aspect of viruses that causes controversy over it being classified as living is its manner of reproduction.
Viruses do reproduce, like a living organism. However, they cannot do so without a host cell, so they are unable to reproduce on their own, which means that they are not living.
Hope this helps!
