What is primary and secondary constriction in chromosomes?
The primary constriction refers to the narrow waist region in a chromosome known as the centromere, which plays a role in chromosome segregation during cell division. The secondary constriction is a region on a chromosome where the nucleolus organizer region (NOR) is located, responsible for producing ribosomal RNA.
What is the condensed form of DNA referred as?
The highly condensed forms of DNA (and proteins) are known as chromosomes.
What is a chromosome in its condensed form called?
Chromatin
What is a sat chromosome?
A sat chromosome, short for satellite chromosome, is a chromosome with a secondary constriction that contains highly repetitive DNA sequences called satellite DNA. These regions appear as small, secondary appendages on the chromosome and play a role in chromosome structure and organization.
Is chromosomes eukaryotes or prokaryotes?
Chromosome is a condensed form of the DNA, not an organism. Therefore, it doesn't fit into either of the categories because it is not an organism to begin with. However, a chromosome is only found in a eukaryote because the formation and the split of a chromosome is part of mitosis, a division of the nucleus.

Doubled rod of condensed chromatin?
The doubled rod of condensed chromatin is known as a chromosome. Chromosomes are tightly packed structures of DNA and protein that contain the genetic information of an organism. During cell division, chromosomes condense further to facilitate separation and distribution of genetic material to daughter cells.
During cell division each single long strand of DNA becomes fully condensed in the form of a?
During interphase, DNA replicates and becomes fully condensed in the form of sister chromatids. When the sister chromatids separate, they will each be called a chromosome.
What causes Increase filtration fraction in glomerulus?
efferent arteriolar constriction.
What is primary and secondary constriction?
Primary constriction refers to the central region of a chromosome where the two sister chromatids are joined, known as the centromere. It plays a crucial role in the proper segregation of chromosomes during cell division. Secondary constriction, on the other hand, is a region outside the primary constriction, often associated with the nucleolar organizer regions that contain genes for ribosomal RNA. This secondary constriction can be involved in the formation of nucleoli during interphase.
What are the causes of airway constriction?
Allergic reactions, medical conditions like asthma
What condition is carried on a chromosome other then the sex chromosome?
The gene that causes cystic fibrosis is located on chromosome 7, which is an autosome, not a sex chromosome.

However, a chromosome is only found in a eukaryote because the formation and the split of a chromosome is part of mitosis, a division of the nucleus.
What is the best stage of Mitosis to study chromosome morphology?
The best stage of mitosis to study chromosome morphology is metaphase, as this is when the chromosomes are fully condensed and aligned along the metaphase plate in preparation for separation.
