are dna and chromosomes the same thing?
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.

Answer: DNA ( deoxyribonucleic acid) is a chemical substance which is called as the genetic material of all living organisms. It is packaged into the threadlike structure, called as chromosomes. This means that chromosomes are composed of a chemical substance, which is called as DNA.

The main difference between chromatin and chromosome is that chromatin consists of the unravelled condensed structure of DNA for the purpose of packaging into the nucleus whereas chromosome consists of the highest condensed structure of the DNA doublehelix for the proper separation of the genetic material between ...

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.

While the chromosomes for other parts of the body are the same size and shape — forming an identical pairing — the X and Y chromosomes have different structures. The X chromosome is significantly longer than the Y chromosome and contains hundreds more genes.

Genomic DNA is DNA that is part of a organism's chromosomes. A Plasmid is small loop of DNA which is separate. Bacteria typically have one circular chromosome, but a variable number of plasmid which they swap with other bacterial of their type.

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. It is a single, very long strand of DNA.

Chromosomes are thread-like structures located inside the nucleus of animal and plant cells. Each chromosome is made of protein and a single molecule of deoxyribonucleic acid (DNA). Passed from parents to offspring, DNA contains the specific instructions that make each type of living creature unique.

Expert Answer Chromosomes also contain chemical substances that govern the function of genes. The human body consists of millions of cells; each cell (liver, intestinal etc) contains 23 pairs of chromosomes except for germ cells (egg and sperm) and red blood cells.

The basic construction of chromosomes (made of chromatin) and structure (long but scrunched up) is the same in all animals. The difference is that each species has its own set number of chromosomes. For instance, all human cells (except gametes) have 46 chromosomes.

Chromosomes also contain chemical substances that govern the function of genes. The human body consists of millions of cells; each cell (liver, intestinal etc) contains 23 pairs of chromosomes except for germ cells (egg and sperm) and red blood cells. Thus a total of 46 chromosomes are present in human cells.

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.

The structure of X and Y chromosomes While the chromosomes for other parts of the body are the same size and shape — forming an identical pairing — the X and Y chromosomes have different structures. The X chromosome is significantly longer than the Y chromosome and contains hundreds more genes.

Chromosomes contain tightly packed DNA molecules while in case of chromatids, the DNA molecules are unwound. 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. ... Homologous chromosomes are exact to each other.

A genome is an organism's complete set of DNA. If the DNA code is a set of instructions that's carefully organised into paragraphs (genes) and chapters (chromosomes), then the entire manual from start to finish would be the genome. Almost every human's genome, chromosomes and genes are organised in the same way.

Genes are made up of DNA. Each chromosome contains many genes.
