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.
DNA is a long, double helix. When you take that helix and wind it tightly around proteins called histones, then it is known as a chromosome.
Chromosomes are hole bunch of DNA, while the genes is a part of the DNA.
A gene is the specific section of DNA that codes for a functional product (i.e. a protein). Chromosomes are tightly packed forms of DNA and proteins - which contain genes.
They are all like mega different like. cromosoms are like weird , jeans are crazy an' cells are rabid
Chromosomes are compact structures of DNA and protein.
Genes are found in DNA (on chromosomes) and are the sections of DNA that code for a functional product (a protein).
Just like a gig
Chromosomes contain genes which are segments of DNA.
Chromosomes are the form of DNA during mitosis.
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.
the genomic DNA large and is the one that forms chromosomes. however, the plasmedic DNA is a small circular vector of DNA (3 kb - 5 kb)
Chromosomes are long strands of DNA which are held together by proteins.
DNA is in genes, and genes are in chromosomes.
Chromosomes of eukaryotes are composed of DNA and protein. Chromosomes of prokaryotes have DNA only.
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
Chromosomes contain genes which are segments of DNA.
Homologous chromosomes are individual chromosomes inherited from each parent. Sister chromatids are the result of DNA replication, and the are identical.
Chromosomes are the form of DNA during mitosis.
Chromosomes represent the very condensed form of the DNA, that develop during cell division. Chromatin is the loose form of DNA that goes under a series of condensation steps (nucleosome-chains, solenoids and finally chromosomes) in order to be able to split DNA in equal amounts between the 2 new cells.
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.
the genomic DNA large and is the one that forms chromosomes. however, the plasmedic DNA is a small circular vector of DNA (3 kb - 5 kb)
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)
