How many dna are in a chromosome
WebChromosomes are made up of DNA and are the carriers of genetic information. Human beings typically have 23 pairs of chromosomes, for a total of 46 chromosomes. Each pair is inherited from the mother and the other from the father. This means that each parent contributes 23 chromosomes to their child, and both parents together contribute a total ... WebAug 19, 2024 · How many DNA molecules make up a chromosome? 1 DNA strand- This means when you break the double helix and one separate strand I thought one chromatid contain 1 DNA strand and 2 chromatids make a chromosome and 1 DNA molecule. So in a diploid cell you have 46 DNA molecules or 92 strands.
