In the nucleus of each cell, the DNA molecule (which determines traits) is packaged into thread-like structures called chromosomes. Each chromosome is made up of DNA tightly coiled many times around proteins called histones that support its structure. Chromosomes are not visible in the cell's nucleus-not even under a microscope-when the cell is not dividing. Chromosomes are not always visible because they usually are uncoiled inside the nucleus as loose strands called chromatin. When it is time for the cell toperform meiosis or mitosis, they condense and wrap up tightly. The tightly wound DNA is the chromosome (3). Most of what researchers know about chromosomes was learned by observing chromosomes during cell division (1).
your welcome :) have a nice day!
What else can I help you with?
What are the importance of chromosomes?
chromosomes are filamentous structures which are present in the nucleus as chromatin reticulum and are visible only during cell division..this is what i know about choromos..lol
What is the evidence for chromosomes are important in inheritance?
Chromosomes are essential in inheritance because they contain the genetic material, DNA, that carries the instructions for making proteins and determining an organism's traits. Through the process of meiosis, chromosomes are passed from parents to offspring, ensuring that genetic information is transmitted accurately. Genetic disorders resulting from chromosomal abnormalities further highlight the importance of chromosomes in inheritance.
What discovery in the 1900 supported Mendel's ideas?
Chromosomes
How do you remember chromosome?
To remember the term "chromosome," think of its Greek roots: "chromo" meaning color and "some" meaning body, which reflects how chromosomes can be stained to reveal distinct colors. Additionally, you can associate chromosomes with their role in genetics, as they house DNA and are crucial for heredity. Visualizing chromosomes as tightly coiled structures helps reinforce their importance in cell division and genetic information.
How many chromosomes do lobsters have?
A lobster has 100 chromosomes. Humans have 46 chromosomes, the same as a lizard. A dog has 78 chromosomes, and a fly has 12 chromosomes.
What is the importance about chromosomes in pregnancy?
Chromosomes decide the gender of the child.

What is the importance of chromosomes in nucleus?
The overall importance of chromosomes is that they contain genetic information, DNA, which is used as a plan to create every component of the human body. Generally speaking, DNA codes for all genes and regulatory elements. Essentiallly, chromosomes carry the instructions for new cell creation, cell division, and how every minute detail should be.
Walter sutton investigated the number of what in a grass hoper?
Walter Sutton investigated the number of chromosomes in a grasshopper. He discovered that grasshoppers have a specific number of chromosomes, which contributed to the understanding of genetics and the role of chromosomes in heredity. His work laid the foundation for the chromosome theory of inheritance, highlighting the importance of chromosomes in the transmission of genetic information.

What is the importance of meiosis in heredity and natural selection?
this is where the genes are mixed up, and it allows genes to be exchanged across chromosomes and randomizes the assortment of chromosomes to the offspring.

What has the author R G Beilharz written?
R. G. Beilharz has written: 'The importance of the sex-chromosome in quantitative inheritance' -- subject(s): Heredity, Sex chromosomes
All chromosomes except the X and Y sex chromosomes are called?
homologous chromosomes and autosomal chromosomes
What is the importance of cell division in medicine and agriculture?
Interphase - As the cell prepares for mitosis, the chromosomes replicate during the S phase of interphase.Prophase - The replicated chromatids begin to coil into recognizable chromosomes; the nuclear membrane fragments; centrioles move to form the cell's poles; spindle fibers form; nucleolus disintegrates.Metaphase - Chromosomes attach to spindle fibers at their centromeres and then move to the equator.Anaphase - Chromatids, now called daughter chromosomes, separate toward the poles.Telophase - The nuclear membranes and nucleoli re-form; spindle fibers fragment; the chromosomes unwind and change from chromosomes to chromatin.Daughter Cells: Cytokinesis occurs and twoRead more: What_is_happening_on_each_stages_of_mitosis
