1) how is dna condensed to form a chromosome?
2) what is the difference of mechanism genes and the dna
segments between them?
3) what is the difference between a gene expression and the
genetic code?
(will give brainliest if answered correctly)

1) When chromatin condenses, it can be seen that eukaryotic DNA is not only a long chain, but is also divided into linear pieces called chromosomes.

2) Genes are segments of deoxyribonucleic acid (DNA) that contain the code for a specific protein whose function is performed in one or more types of body cells. Chromosomes are structures that are found within cells and that contain the genes of a person.

3)Gene expression is the process that allows proteins to be obtained from genes. The code defines the relationship between each sequence of three nucleotides, called codon, and each amino acid.
