Answer: option d.hydrogen bonds between nitrogen base Pairs
Explanation:
DNA is called a Deoxyribonucleic acids, it contains hereditory information in the cell. DNA is located in nucleus of human cell. DNA consist of nucleotide strands that comprises of a sugar and oxyribose bound on a partto a phosphate group and bound on the other part to a nitrogenous base. The Nitrogenous base consist of Adenine, thymine, guanine and cytosine which are complementary base Pairs. They are grouped into 2 distinct classes called purines (double-ringed structures) and pyrimidines (single-ringed structures). The nitrogenous bases forms a ladder and pairs with bases on the other side commonly called rungs. Each complementary nucleotides purine with pyrimidine are held together by hydrogen bonds.A hydrogen bond is a known as chemical bond that is relatively weak and occurs only between hydrogen atoms along with or and electronegative atoms, e.g oxygen, nitrogen e.t.c. Hydrogen bonds usually occur in short length or distances and are formed quickly or easily and ca also broken.
Answer:
All blood types are made compatible with each other.
Explanation:
The different types of blood showed that not all blood types are compatible with each other. This is the reason why when a doctor transfer blood, this has to be compatible with the person's blood. Otherwise, the immune system will recognize the blood cells as antigens and proceed to destroy it.
Red blood cells in its surface can have different types of proteins, the proteins or lack of it that a person has determines the type of blood (A, B, AB). Also, if the cell has the Rh protein it will be positive, and if it does not have it, it will be negative. In total, we have eight blood types A+, A-,B+, B-,AB+, AB-,0+,0- and the compatibility depends on the proteins that a person has.
