Question
Threadlike structures that carry DNA is:
- Allele
- Genotype
- Chromosome
- Phenotype
Hint:
Dna is present on these.
The correct answer is: Chromosome
- 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 that support its structure.
