How many dna molecules are present in your diploid cells
Tcecarenko [31]

Answer:

92 molecules

Explanation:

DNA or Deoxyribosenucleic acid is polynucleotide made up of several nucleotides containing the genetic information of an organism. In the nucleus of each cell, the DNA molecule is packaged into thread-like structures called chromosomes. Each chromosome is made up of DNA, tightly coiled many times around proteins called histones to support its stucture.

Human cells, like myself, contains 23 pairs of chromosomes (46 chromosomes in total). Each pair coming from each parent. Each chromosome is formed by two strands of DNA held together by hydrogen bonds forming the DNA double-helical structure. These two DNA strands form a base pair, which is a unit of two nucleotide bases bound to each other by hydrogen bonds. According to the complementary base pairing rule, Adenine (A) pairs with Thymine (T) while Guanine pairs with Cytosine (C).

Since there are 46 chromosomes in a diploid human cell and each chromosome consists of 2 DNA strands, then, there are 46 × 2 = 92 strands/molecules of DNA in each human diploid cell.
