The smallest unit is the gene, which can be any length of base pairs, A, C, T, and G. All genes fit on DNA. DNA is a double helix shape, meaning it looks like a ladder twisted around in a spiral shape. The "rungs" are the bases, and the long part is made out of a sugar, deoxyribose, and a phosphate group. All that DNA is then condensed into chromosomes.

What are the links between DNA genes chromosomes and proteins?
Chromosomes are long strands of DNA which are held together by proteins.
What is the relationship between chromosomes and genes and between genes and DNA?
Chromosomes are structures made of DNA that carry genes. Genes are segments of DNA that contain the instructions for making proteins. DNA is the molecule that carries the genetic information needed for the development, functioning, and reproduction of living organisms.
What is the relationship between a chromosome and DNA?
Chromosomes are long strands of DNA that contain our genetic information. DNA is the molecule that makes up chromosomes, and it is organized into genes on the chromosomes. Each cell in our body contains a set of chromosomes that help determine our traits and characteristics.
What is the difference between a chromosome and a DNA molecule?
The difference between a chromosome and a DNA molecule is that a chromosome is a single DNA molecule associated with proteins and a DNA molecule is a long thin molecule that stores genetic information.
What is the difference between bacterial cell and bacterial chromosomes?
besides the fact that most DNA is encased in a protective membrane, probably the most significant difference is that prokaryote DNA does not have introns and exons nor is it in a diploid state. besides the fact that most DNA is encased in a protective membrane, probably the most significant difference is that prokaryote DNA does not have introns and exons nor is it in a diploid state.
What is the link between DNA and chromosomes?
DNA is housed in chromosomes.
How is DNA different from the DNA found in chromosomes?
Do you mean what is the difference between DNA w/in chromosomes and DNA that is not? the DNA in chromosomes is tightly bound up (to histones) and therefore can not be accessed to be transcribed or replicated. Also this DNA may be methylated, or otherwise made inaccessible to enzymes that might act on it
Difference between sister chromatids and homologous chromosomes?
Homologous chromosomes are individual chromosomes inherited from each parent. Sister chromatids are the result of DNA replication, and the are identical.
What is the difference between replicated chromosomes and unreplicated chromosomes in DNA?
Replicated chromosomes have undergone DNA replication, producing two identical sister chromatids joined by a centromere. Unreplicated chromosomes have not undergone DNA replication and consist of a single chromatid. Replicated chromosomes are found during the S phase of the cell cycle, while unreplicated chromosomes are present in the G1 phase.
What is the difference in DNA between parent cells and daughter cells in meiosis?
Parent cells are diploids, and daughter cells are haploids. Therefore, the daughter cells have half of the the number of chromosomes as the parent cells. (chromosomes are DNA)
What are the links between DNA genes chromosomes and proteins?
Chromosomes are long strands of DNA which are held together by proteins.
What is the difference between DNA genes chromosomes?
Genes are basic units of Inheritance and are the templates for the creation of proteins, whereas Chromosomes are the molecular structures within the nucleus that contain genes.
What is the difference between chromosomes and genes?
Chromosomes are structures within cells that contain DNA, while genes are specific segments of DNA that provide instructions for a particular trait. Chromosomes house many genes, along with other DNA sequences, and are inherited in pairs, one from each parent. Genes determine specific traits, such as eye color or blood type.
What is the relationship between chromosomes and genes and between genes and DNA?
Chromosomes are structures made of DNA that carry genes. Genes are segments of DNA that contain the instructions for making proteins. DNA is the molecule that carries the genetic information needed for the development, functioning, and reproduction of living organisms.

What is the relationship between DNA and cromosomes?
Chromosomes are in DNA (Deoxyribo Nucleic Acid)
