Answer:
Mutation. A mistake made while DNA copies which causes changes in DNA
Explanation:
Answer:
In the most general case of x bases and y bases per codon, the total number of possible codons is equal to xy .
In the case of the hypothetical Martian life-forms, is the minimum codon length needed to specify 17 amino acids is 5 (25 = 32), with some redundancy (meaning that more than one codon could code for the same amino acid). For life on Earth, x = 4 and y = 3; thus the number of codons is 43, or 64. Because there are only 20 amino acids, there is a lot of redundancy in the code (there are several codons for each amino acid).

Answer: Life would cease to exist.
Explanation:
The carbon elements is one of the most important elements in the compound that make up living organisms. It is found: in the remains of living organisms; as fossil fuels such as coal, coke and natural gas; as inorganic salts such as carbonates; in water bodies and as gas carbondioxide which makes up 0.03% of air.
Carbon is continuously being circulated in the atmosphere through a process called the CARBON CYCLE. This involves the removal and addition of carbon to the carbondioxide in the atmosphere.
Life would indeed cease to exist if this carbon cycle stops due to the importance of carbon to functioning of living organisms. Important processes which bring about the recycling of carbon between living ( biotic) and non living (abiotic) components of an ecosystem are:
--> photosynthesis: the process used by green plants to remove carbon through carbondioxide from the atmosphere for manufacturing of their food.
--> respiration: animals respire to break down sugar leading to liberation of carbondioxide and water as wastes
--> and decay: decomposers feeds on remains and waste to bring about decay, thus complex carbon compounds are broken down to set free carbondioxide which returns to the atmosphere.
All the above processes are carried out by living organisms to maintain a functioning ecosystem by enabling a linear flow of energy through it.
