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.

the glands which are associated with each description is given below:

pancreas - is an endocrine and exocrine gland that secretes juices with enzymes for digestion. salivary glands- with protection and digestion in the mouth. liver- secretes bile for digestion.   lachrymal glands - secrete tears to moisten eyes and protect them from particles and infection.   sweat gland -regulates water, salt, and temperature. oil glands - to form a protective barrier on the skin.   goblet cells - secrete mucus for protection.
