During binary fission in a bacterial cell, a base pair is changed from adenine to cytosine due to a random mutation.
Binary fission is a type of asexual reproduction through which a bacteria divides and its body is separated into two new bodies.
If during binary fission in a bacterial cell, a base pair is changed from adenine to cytosine, it is because of a random mutation. A mutation is a genetic alteration or a change in the DNA sequence which results in the generation of a variant. Mutations in the DNA sequence which occur without any specific pattern is known as a random mutation.

Answer:
This question lacks options, options are:
A) ATP
B) NADP
C) Pryuvate
D) glucose
E) acetyl-CoA.
The correct answer is C) Pyruvate.
Explanation:
Pyruvate is a very important compound for the cell since it is a key substrate for energy production and glucose synthesis (neo-glycogenesis), that is, pyruvate is the end product of glucose breakdown in glycolysis. Before entering the mitochondria, it can be converted to lactate, through an anaerobic reaction (in the absence or under oxygen supply) of low performance in energy production, when the main pathway is interfered with. It can also be converted to the amino acid alanine. Within the mitochondria, it can be transformed, by pyruvate dehydrogenase (PDH), into acetyl-coenzyme A (acetyl-CoA), the entry point (substrate) of the Krebs cycle. In addition, by means of pyruvate carboxylase, it can be transformed into oxalacetate, which constitutes the first step in neoglycogenesis.
Answer:
3.dominant alleles more frequent than recessive alleles
Explanation:
To achieve hard-Weinberg equilibrium, certain conditions must be made.
These conditions are:
1. There is noo mutation,
2. Existence of random mating,
3. There should be no natural selection
4. There is the infinite population size
5. No migration
Hence, in this case, the correct answer is option 3, which is not a condition to be made for Hard-Weinberg equilibrium
