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 else can I help you with?
A species that contains two copies of each chromosome is called?
A species that contains two copies of each chromosome is called diploid. Each pair of chromosomes, one from each parent, make up a diploid set in the organism.
What is chromatid?
A chromatid is one half of a duplicated chromosome, joined together by a centromere. Each chromatid contains identical genetic material and is essential for proper chromosome segregation during cell division.
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.
Which two chemical compounds make up a chromosome?
The two chemical components of chromosomes are DNA and proteins. Original researchers thought that protein was the genetic material because proteins had specific functions with great heterogeneity.
How many chromatids are involved in crossing over of a homologous pair of chromosomes?
Crossing over involves the exchange of genetic material between homologous chromosomes during meiosis. Each homologous pair consists of four chromatids (two from each chromosome), and crossing over occurs between a pair of chromatids from each homologous chromosome. This results in the exchange of genetic material between the chromatids.
Two of these make a chromosome?
Two chromatids connected at the centromere make up one chromosome.
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 are two rod like parts that make up a chromosome are called?
Chromatids
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
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.
Which are the two main parts that make up a chromosome?
A centromere and a pair of sister chromatids
Name a list of statements of fermentation?
There are two things that make up fermentation. The two things that make up fermentation are lactic acid and propionic acid.
What are the compounds which make up a chromosome?
DNA molecules
How many DNAmolecules make up each original chromosome?
A chromosome is formed from a single DNA molecule.
