The complete set of hereditary instructions contained in the dna genome 2. important biological molecules with a complex folded structure proteins 3. structure found in the cell that contains tightly wound strands of dna gene 4. a sequence of nucleotides in a strand of dna that code for a specific product, which is usually protein chromosome

1. Genome

2. Protein

3. Chromosome

4. Gene

Explanation:

Number 3 and 4 are wrongly placed with their answers.

DNA is the storage molecule of genetic material in living cells, however, in order for these long chains of DNA to fit into the cell, they are wrapped around certain proteins called HISTONES to form Chromatin. Chromatin, then undergoes further coiling and folding to form thread-like structures called chromosome. The genetic material is seen and transferred as chromosomes.

The DNA also contains segments that comprises of nucleotide sequences called GENES. These nucleotide-containing segments encode the formation of functional gene products (RNA or proteins). Genes hold the information to build and maintain an organisms cell. It is referred to as the molecular unit of heredity because they also encode information for passing genetic traits to offsprings.

all matter is made up of atoms

in any element all atoms are the same

elements in a compound are always in a constant ratio: apex
