Answer:
Cytosine & Guanine
Explanation:
Living organisms contain in their cell a biomolecule responsible for the storage and transmission of genetic information called NUCLEIC ACID. DNA is one of the two nucleic acids found in living cells. However, the DNA molecule is a polymer made up of monomeric units called NUCLEOTIDES.
Nucleotides of a DNA are made up of three components namely: 5-carbon sugar (deoxyribose), phosphate group, and a nitrogenous base (Adenine, Guanine, Cytosine and Thymine). Hence, based on the question, Cytosine & Guanine are the components (nitrogenous base) found in the DNA of all living organism.
Answer:
160
Explanation:
If p = frequency of dominant allele and q = frequency of recessive allele according to Hardy-Weinberg equilibrium,
p + q = 1
p² + 2pq + q² = 1
where p² = frequency of dominant homozygous genotype
q² = frequency of recessive homozygous genotype
2pq = frequency of heterozygous genotype
Here,
b = 4% = 0.04
bb = 0.04 * 0.04 = 0.0016
Number of individuals in population = 100000
Number of homozygous bb individuals = 0.0016 * 100000 = 160
<span>carbon has four valence electrons in its outermost shell .. which makes it able to form four bonds to complete its valence shell ..
it forms large number of chains with its own self which makes it useful .. also it forms bonds with oxygen and hydrogen forming large organic compounds of great importance. </span>
