Which one of the following statements describes the relationship between genes, chromosomes and DNA
a) genes, the basic unit of heredity, are located on chromosomes, which consist of strands of DNA
b) genes are composed of chromosome and DNA
C) chromosomes the basic unit if heredity, direct the genes and the DNA
d)DNA houses both genes and chromosomes in its rod-shaped structures
I believe the answer is C
what is wrong with a?
Are you asking why did'nt I choose a as a possible answer or the way A is worded?
Why didn't you choose A?

Actually, the correct answer is a) genes, the basic unit of heredity, are located on chromosomes, which consist of strands of DNA. To understand why this statement is true, let's break it down:
1. Genes: Genes are the basic units of heredity. They are responsible for transmitting traits from parents to offspring. Genes contain specific instructions in the form of a DNA sequence for producing proteins and determining traits.
2. Chromosomes: Chromosomes are structures within cells that contain DNA. They are thread-like structures made up of tightly coiled DNA molecules. Humans typically have 46 chromosomes (23 pairs) in each cell.
3. DNA: DNA stands for Deoxyribonucleic Acid. It is a long, double-stranded molecule that carries the genetic instructions for the development, functioning, growth, and reproduction of all living organisms. DNA is the chemical building block of chromosomes.
Therefore, statement a) correctly explains the relationship between genes, chromosomes, and DNA. Genes are located on chromosomes, which are made up of strands of DNA.
