Answer:
you could literally just look them up
1. Deoxyribonucleic Acid
2. In biology, a gene is a basic unit of heredity and a sequence of nucleotides in DNA or RNA that encodes the synthesis of a gene product, either RNA or protein. During gene expression, the DNA is first copied into RNA.
3. nucleus
Chromosomes are thread-like structures located inside the nucleus of animal and plant cells. Each chromosome is made of protein and a single molecule of deoxyribonucleic acid (DNA).
4. As described above, DNA can be found in three organelles: the nucleus, mitochondrion, and chloroplast. Only eukaryotes have a nucleus, which is a large structure that's surrounded by a membrane. Nuclear DNA comes in the form of long, linear pieces of DNA called chromosomes.
