{'chromosome': [2, 0, 0, 1], 'dna': [3, 1, 1, 2], 'rna': [3, 0, 0, 1], 'protein': [2, 0, 2, 1], 'amino acid': [0, 0, 0, 1], 'lipid': [3, 0, 2, 2], 'sugar': [0, 0, 0, 1]}

In a chromosome, the correct answer is option 3, which is DNA and protein. DNA, or deoxyribonucleic acid, is the main component of a chromosome. It contains the genetic information that codes for the production of specific proteins. These proteins play a crucial role in various cellular processes and functions. The DNA molecule is tightly coiled and organized in a chromosome structure. Along with DNA, proteins known as histones are also present in a chromosome. Histones help in packing and organizing the DNA strands. Together, the DNA and protein composition of a chromosome ensure the proper inheritance and functioning of genetic information. It is important to note that lipids, amino acids, and sugars are not typically present in chromosomes.
