what is the relationship between chromosome and dna?
6542
In the nucleus of each cell, the DNA molecule 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.

Genes are located on chromosomes, which are large pieces of DNA contained in a eukaryotic cell's nucleus.

DNA contains the instructions, genes, to make proteins that tell what genetic traits the person will have. The DNA along with the proteins make up the chromosomes. The chromosomes are then passed on to the offspring, and with the DNA inside the chromosomes and translation of the genes, its traits are decided.

Now, a chromosome is made up of two strands which are identical to each other and these are called Chromatids. The major difference between Chromosome and Chromatid are summarized below. A chromosome is made up two Identical Sister Chromatids. And each sister chromatids are joined at the centromere.

chromosomes are the strands of DNA that carry genes and gametes are the cells that are formed after meiosis and specifically carry the haploid number of chromosomes.

Genes are made of DNA. ... Chromosomes are packages of compact DNA. How many chromosomes does a human cell hold?
197168
DNA is organized into structures called chromosomes. As shown in the animation, most humans have a total of 46 chromosomes in each cell: 22 pairs of matching chromosomes (autosomes) and one pair of sex chromosomes (allosomes).

A chromosome is made of both one DNA molecule wound around small protein molecules whereas DNA is just one large molecule called deoxyribose nucleic acid.

Genes are subsections of DNA molecules linked together that create a particular characteristic. Each chromosome is made up of a single DNA molecule coiled around histone proteins. Research dating back to the 1800s shows that every living creature has a specific set of chromosomes in the nucleus of each of its cells.

A chromosome is made up of a single, double-stranded DNA molecule while a chromatid comprises of two DNA strands joining collectively by their centromere. The chromatids contain a substance called chromatin. ... In the case of chromatids, each sister chromatid is an exact replication of the other.

Genes are contained in chromosomes, which are in the cell nucleus. A chromosome contains hundreds to thousands of genes. Every normal human cell contains 23 pairs of chromosomes, for a total of 46 chromosomes.

What is the relationship between cancer and DNA? Scientists think that cancer begins when something damages a portion of the DNA in a chromosome. The damage causes a change in the DNA called a mutation. DNA contains all the instructions necessary for life.

Genes are segments of deoxyribonucleic acid (DNA) that contain the code for a specific protein that functions in one or more types of cells in the body. Chromosomes are structures within cells that contain a person's genes. Genes are contained in chromosomes, which are in the cell nucleus.

Functions of chromosomes: DNA present on the chromosome not only carries most of the genetic information but also controls the hereditary transfer. Chromosomes are essential for the process of cell division, replication, division, and creation of daughter cells.

The chromosomes and genes are made of DNA, which is short for deoxyribonucleic (say: dee-ox-see-ri-bo-nyoo-CLAY-ik) acid. Most cells have one nucleus (say: NOO-clee-us). The nucleus is a small egg-shaped structure inside the cell which acts like the brain of the cell.

what is the relationship between DNA and proteins? a DNA molecule that contains the information to code for one specific protein. The sequence of bases in the DNA molecule determines the sequence of amino acids in a protein.

chromatin. Chromatin is a complex of DNA and proteins that forms chromosomes within the nucleus of eukaryotic cells. ... During cell division, the structure of the chromatin and chromosomes are visible under a light microscope, and they change in shape as the DNA is duplicated and separated into two cells.
