Starting from my First cousin family, I know for sure that the Uncle is is a carrier (Aa) and he must have married a wife who is also a carrier (Aa) and that is how they got an affected son. Thus, this leads to the fact that either both of my grandparents are carriers (Aa x Aa) or only one of them is a carrier (Aa x AA). As a result, the chances that my mom (who is related to the uncle who has a defected child) is a carrier is either (2/3 or 1/2) depending if my grandparents genotype, respectively. Thus, if my mom chances of being a carrier is 1/2 then my chance of being a carrier is 1/4. (given that my dad is not a carrier b/c CF is a rare disease) However, if my mom chance of being a carrier is 2/3 then my chance of being a carrier is (2/3)x(1/2)=(1/3) As a result, I could either be 1/4 or 1/3. But since the answer only provide the choice of 1/4 and not 1/3. This leave 25% is the correct answer.</span>
The four types of nitrogen bases of dna nucleotides are:
- Adenine (A)
- Cytosine (C)
- Ganine (G)
- Thymine (T).
These bases form specific pairs (A with T, and G with C).
<h3>What is DNA nucleotides?</h3>
Nucleotides can be defined as those organic substances consisting of a nucleoside and a phosphate.
They serve as monomeric units of the nucleic acid polymers –
- Deoxyribonucleic acid
- Ribonucleic acid,
So therefore, the four types of nitrogen bases of dna nucleotides are:
- Adenine (A)
- Cytosine (C)
- Ganine (G)
- Thymine (T).

Golgi Apparatus - Make, process, and package proteins
Nucleus - Stores the DNA and coordinates the cell's activities
Mitochondria - Make energy out of food
Vacuole - Storage for food and water
Lysosome - Contains digestive enzymes that help break down food
Plant cells (only) -
Cell wall - Protection and support
Chloroplast - Uses sunlight to create food using photosynthesis

Its because a long spine cacti can reproduce more because it has more survival capacity than the short spine cacti and because of this reason the short spine cacti cannot protect it self because it has a shorter spine that could protect itself from danger.
