The two halves of a chromosome are called chromatids, or, more fully, sister-chromatids.
Each sister-chromatid contains one molecule of DNA. The two DNA molecules of one chromosome are, barring occasional copying errors, genetically identical, because they were formed from the same original DNA molecule at the most recent replication.

A cell condition in which each chromosome is doubled?
This is known as polyploidy, where cells have extra sets of chromosomes. Polyploidy can occur naturally or be induced experimentally, and it can lead to changes in an organism's characteristics and traits. This phenomenon is commonly observed in plants.
What chromatids identical halves of a duplicated parent chromosome formed during the prophase stage of mitosis the halves are held together by a centromere?
The chromatids are the identical halves of a duplicated chromosome that are held together by a centromere. During the prophase stage of mitosis, the chromatids condense and become visible as distinct structures. These chromatids will eventually separate during anaphase and move to opposite poles of the cell.
What is the name of the point at which the two halves of duplicated chromosomes are connected?
Ah, that's a happy little detail called the centromere, friend. It's like the glue that holds the duplicated chromosomes together, ensuring they are distributed accurately when cells divide. Just a tiny touch of detail that plays a big role in the beautiful process of cell division.
Are chromosomes and chromatid the same thing?
No, chromosomes and chromatids are not the same. Chromosomes are long strands of DNA that contain genetic information, while chromatids are one of the two identical halves of a replicated chromosome held together by a centromere during cell division.
What holds the two halves of a DNA double helix together?
The two halves of a DNA double helix are held together by hydrogen bonds between complementary nitrogenous bases. Adenine pairs with thymine and guanine pairs with cytosine. This base pairing allows for the specificity and stability of the DNA molecule.

How is chromosome and chromatids related?
Chromatin is intertwinted mass of fine thread-like structure made of DNA and protein. During cell division (mitosis and meiosis), chromatin condenses to form thicker rod-like structures called chromosomes. Each chromosome consists of two similar halves called chromatids. Formation of chromosomes having two similar halves or chromatids is meant for equitable distribution of chromatin which is hereditary material.

What is a short thick coil of DNA?
A short, thick coil of DNA is called a nucleosome. Nucleosomes are composed of DNA wrapped around histone proteins, forming a compact structure that helps regulate gene expression and protect the DNA molecule.
What is all the label parts of the chromosome?
A chromosome consists of several key components: the centromere, which is the constricted region that divides the chromosome into two arms; telomeres, which are repetitive sequences at the ends that protect the chromosome from deterioration; and chromatids, which are the two identical halves formed during DNA replication. Additionally, chromosomes contain genes, which are segments of DNA that code for proteins, and regulatory regions that control gene expression. The overall structure is organized into a double helix of DNA wrapped around histone proteins, forming a compact and stable structure essential for cellular division and function.
What does chromatin have to do with chromosomes?
Chromatin is intertwinted mass of fine thread-like structure made of DNA and protein. During cell division (mitosis and meiosis), chromatin condenses to form thicker rod-like structures called chromosomes. Each chromosome consists of two similar halves called chromatids.

Do diatoms have a cell wall made of two halves called valves?
Yes they do. According to my online schooling reading material they do have two halves called valves.
Halves of the earth?
the center of the earth is called the halves of the earth
What are the two halves of the brain called?
right hemisphere and left hemisphere
Is the chromosome of a bacterium wrapped around proteins?
In order to fit within a cell, DNA becomes more compact by wrapping tightly around associated proteins. Chromatids are duplicate halves of a chromosome.
What are the two halves of the world called?
they are called the hemispheres
