Chromosomes are comprised of nucleotides and nitrogen base pairs. The nucleotides make up the columns of the DNA structure, and are repeating sequences of a 5-carbon sugar and a phosphate.
The "rungs" of the DNA structure, similar to the rungs (steps) of a ladder, and made up of four variations of nitrogen base pairs.

What is chromatid?
* the two exact copies of DNA that make up each chromosome.
Describe the chromatids that make up a chromosome when a cell is ready to divide?
Describe the chromatic that make up a chromosome when a cell is ready to split
What is the structure at the center of the chromosomes where sister chromatids are attached?
When sister chromatids are joined together they are held together by proteins, which make up the centromere. The two chromatids together make up a chromosome.
How many chromatids are involved in crossing over of a homologous pair of chromosomes?
four two in each chromosome
What is the region of a chromosome holding the two double strands of replicated DNA together called?
The region of a chromosome holding the two double strands of replicated DNA together is called a centromere. The complex of DNA and protein that makes up eukaryotic chromosome is properly called chromatin.
Two of these make a chromosome?
Two chromatids connected at the centromere make up one chromosome.
What are two rod like parts that make up a chromosome are called?
Chromatids
The two exact copies of DNA that make up a chromosome are called?
Chromatids.
What two structures make up a single replicated chromosome?
DNA and Protein
What 2 main things make up a chromosome?
Doubled stranded DNA and protein molecules
Describe the chromatids that make up a chromosome when a cell is ready to divide.?
Describe the chromatic that make up a chromosome when a cell is ready to split
What two identical bodies make up a duplicated chromosome?
Somatic cell chromosome is made of two identical chromatids
What is chromatid?
* the two exact copies of DNA that make up each chromosome.
Describe the chromatids that make up a chromosome when a cell is ready to divide?
Describe the chromatic that make up a chromosome when a cell is ready to split
Which are the two main parts that make up a chromosome?
A centromere and a pair of sister chromatids
How many chromatids have one chromosome?
Two (2). Before DNA replication, each chromosome is composed of a single chromatid. After replication, but before separation of the chromatids during anaphase, this is true.
What are the compounds which make up a chromosome?
DNA molecules
