The answer to this depends on what components you are talking bout. Are you wondering about basal molecules, or elements?
For in stance, DNA is composed of four different types of nucleobases; adenine, guanine, cytosine, and thymine. Thesebases are joined to a sugar molecule (a deoxyribose sugar in the case of DNA, hence the name DeoxyriboNucleic Acid). These sugar-and-base pairs are called NUCLEOSIDES. Nucleosides are joined together by a phosphate link. Nuclueosides bound to phosphate groups are called NUCLEOTIDES. Nucleotides all consist of 1 phosphate bond, 1 sugar and 1 base. DNA is merely a chain of nucleotides. The major elements composing both bases and sugars in DNA is carbon. Thus...
DNA is primarily composed of the element carbon, and is equally composed of a base, sugar and phosphate link. As for the most common nucleobase? That depends on the organism you are looking at.
d. chromosomes - Chromosomes are structures in the cell nucleus that are composed primarily of DNA. They contain the genetic information required for cell function and growth.
Cytoplasm is composed primarily of water, salts, and organic molecules such as proteins, lipids, and carbohydrates. It also contains various organelles like mitochondria, endoplasmic reticulum, and ribosomes.
Yes, the mitotic spindle is primarily composed of microtubules.
No, adipose tissue is primarily composed of fat cells, not protein.
Breasts are primarily composed of fat tissue, not muscle tissue.
d. chromosomes - Chromosomes are structures in the cell nucleus that are composed primarily of DNA. They contain the genetic information required for cell function and growth.
Chromatin composed of tetramer of histones 2 copies each of Histone H2A, H2B, H3 and H4. DNA is bound on the nucleosome and uses 147 basepairs of DNA.
Cytoplasm is composed primarily of water, salts, and organic molecules such as proteins, lipids, and carbohydrates. It also contains various organelles like mitochondria, endoplasmic reticulum, and ribosomes.
Yes, the mitotic spindle is primarily composed of microtubules.
A DNA molecule is composed of long chains of DNA nucleotides.
The is no known planet composed primarily of Iron Oxide.
No, adipose tissue is primarily composed of fat cells, not protein.
Breasts are primarily composed of fat tissue, not muscle tissue.
Breasts are primarily composed of fat tissue, not muscle tissue.
Genes are composed of DNA. Chromosomes are composed of DNA and proteins. Genes are the sections of DNA which code for a functional product (such as a protein). Chromosomes are the compact, tightly-coiled form of DNA. These appear before the cell undergoes division/replication.
Yes, trees are primarily composed of carbon, which is a key element in their structure and growth.
No, DNA is not amphipathic. Amphipathic molecules have both hydrophilic (water-loving) and hydrophobic (water-fearing) regions, while DNA is primarily composed of nitrogenous bases, sugar molecules, and phosphate groups that do not exhibit such dual nature.
