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.
Chromosomes are long strands of DNA which are held together by proteins.
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.
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.
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.
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.
DNA is housed 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
Homologous chromosomes are individual chromosomes inherited from each parent. Sister chromatids are the result of DNA replication, and the are identical.
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.
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)
Chromosomes are long strands of DNA which are held together by proteins.
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.
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.
