The largest structure is the nucleus, which contains all the genetic material of a cell. Within the nucleus, chromosomes are structures made of DNA that carry genes. Each chromosome consists of tightly coiled DNA, which is made up of sequences of bases (adenine, thymine, cytosine, and guanine). Therefore, the order from largest to smallest is: nucleus, chromosome, DNA, and bases.
Dna consists of 4 bases, adenine is one of the four bases. the 4 bases makes up nucleotide which is a small part of dna. the dna is a small part of a chromosome which is contained in the nucleus
An atom comprises an atomic nucleus with orbiting electrons. So the nucleus is smaller than an atom. To phrase it the opposite way, an atom is alwys larger than the nucleus (of the same atom of course!!)
Every chromosome is a different size so the number of base pairs is different for each chromosome. X chromosome has more that 153 million base pairs (greater that 306 million bases) Y chromosome has around 50 million base pairs (around 100 million bases)
Genes, which are segments of DNA, carry the information that controls traits on a chromosome. Each gene contains the instructions for making specific proteins that determine various characteristics or traits in an organism.
No because a single gene is made up of many bases in a row in a chromosome that may contain anywhere from several hundred to a million or more nitrogen bases.
true
A chromosome is made of DNA, which consists of long chains of nucleotides. These nucleotides are composed of a phosphate group, a sugar molecule, and one of four nitrogenous bases (adenine, thymine, cytosine, or guanine).
X chromosome inactivation is a process that occurs in female mammals where one of the X chromosomes in each cell is randomly inactivated. This ensures that both males and females have similar levels of X chromosome gene products. The inactivated X chromosome condenses into a structure called a Barr body.
DNA contains the genetic instructions for a living cell's function. Chromosomes are thread-like structures that contain DNA and histone proteins. A chromosome is a loosely defined term, and vary widely among different organisms. DNA is a set of instructions, and chromosomes help fit the DNA molecules into a cell's nucleus. Chromosomes are essential units for cellular division and replication to insure genetic diversity.
That A + B /c is A+B/c but you really need to know the answer
The cell having the smallest genome out of all known cells is Mycoplasma genitalium, with 482 genes comprised of 580,000 bases. (An ameba is not the simplest cell, and has more genetic information than a human.)
Each chromosome contains 23 pairs of bases, which are made up of adenine (A) pairing with thymine (T) and cytosine (C) pairing with guanine (G) in DNA molecules. These base pairs form the building blocks of DNA and are essential for genetic information storage and transfer in cells.
