Answer:
The statement suggests ability of existing DNA molecule to replicate itself by the process of DNA replication. Each strand of double helical DNA can serve as template for the synthesis of new complementary DNA strand.
Explanation:
Watson and Crick proposed the double-helical structure of DNA. Accordingly, the DNA molecule is a double helical structure in which two polynucleotide chains are held together by base pairing between the complementary bases of two chains.
There are four nitrogenous bases present in DNA: adenine and guanine (purines) and cytosine and thymine (pyrimidines). Adenine always pairs with thymine and cytosine pairs with guanine base.
According to Watson and Crick, the ability of one DNA strand to base-pair with a complementary DNA strand suggests the existence of the DNA replication process. During DNA replication, each DNA strand should serve as a template to specify the nucleotide sequence of the new DNA strand.

Answer:
Option A
Explanation:
The genotypic frequency for tt (q²) = 36% = 36/100 = 0.36
To calculate for the allelic frequency of t which is q, we have to find the square root of q² to do this. Thus
√q² = √0.36 = 0.6 this q = 0.6
The allelic frequency p for the T allele can then be calculated using this formula p + q = 1
Where q is 0.6 thus p= 1 - 0.6 = 0.4.
This the allelic freq of T is 0.4
Answer:
Both are Homozygous
Explanation:
A Husband and Wife with curly haired husband(CC) and straight haired wife have all their children curly haired because the gene for curly hair is dominant than straight hair. So, in the progeny, curly hair only.
This represents the Mendel’s Law of dominance which is also the Mendel Third Law which states that one of the factors for a pair of inherited traits will be dominant and the other recessive, unless both factors are recessive.
So, the correct option is ‘Both are homozygous'.
