What is the relationship between chromosomes and genes and between genes and DNA?
Chromosomes are structures made of DNA that carry genes. Genes are segments of DNA that contain the instructions for making proteins. DNA is the molecule that carries the genetic information needed for the development, functioning, and reproduction of living organisms.
Explain how DNA genes and chromosomes are related?
Chromosomes are composed of DNA or deoxyribonucleic acid. A section of DNA is called a gene. A single strand of DNA is made up of thousands of genes.
A long molecule that makes up genes and chromosomes?
DNA (Dioxyribonucleic Acid)
How many genes can be stored on a DNA molecule?
A DNA molecule can store thousands of genes. The human genome contains approximately 20,000-25,000 genes, which are stored on 23 pairs of chromosomes. Each gene provides instructions for making a specific protein in the body's cells.
Are genes on DNA and DNA on chromosomes?
Not quite. Don't think of these things being on each other. Genes and chromosomes are made of DNA. DNA is a large, polymeric biomolecule composed of four different types of subunits called nucleotides. The sequence of nucleotides within the DNA molecule can encode information. All the information necessary to encode a protein is called a gene. DNA molecules can be extremely long - extending for millions of nucleotides. A chromosome is a single DNA molecule (encoding thousands of genes) plus associated proteins that provide structure and play key roles in the regulations of genes.
How are genes chromosomes and DNA related?
if a cat has 38 chromosomes in each of its body celss, how many chromosomes will be in each daughter cell after mitosis?
What are the roles of chromosomes DNA and genes in storing genetic material?
Chromosomes are structures composed of DNA that carry genetic information in the form of genes. DNA is the molecule that encodes genetic instructions, while genes are specific segments of DNA that code for specific proteins or RNA molecules. Together, chromosomes, DNA, and genes work to store and transmit genetic material from one generation to the next.
What is located in the nuclei on chromosomes?
it is made up of PROTEINS and DNA MOLECULE, it is located in the nucleus.

Where are the genes held in a cell?
Genes in eukaryotic cells are in three places: the nucleus, mitochondria, and chloroplasts.A gene is a segment of DNA that codes for a polypeptide or for a molecule of RNA, such as a transfer RNA (tRNA) or ribosomal RNA (rRNA). The genes in the nucleus are in chromosomes. A chromosome consists of a molecule of DNA (two after replication of the DNA) and associated proteins.Genes are segments of DNA molecules. A single DNA molecule has numerous genes. For example, humans have 23 chromosomes and about 20,000 to 25,000 genes in a haploid set, so there are, very roughly, a thousand genes on an average chromosome, which is to say along an average molecule of DNA. Genes in mitochondria and chloroplasts are on loops of DNA, like prokaryotic chromosomes. Mitochondria have 37 genes, some of which encode polypeptides, while the others code for rRNA and tRNAs. Chloroplasts have more than this (over 120 in one liverwort).
What is the difference between a chromosome and a DNA molecule?
The difference between a chromosome and a DNA molecule is that a chromosome is a single DNA molecule associated with proteins and a DNA molecule is a long thin molecule that stores genetic information.
What is the difference between chromosomes and genes?
Chromosomes are structures within cells that contain DNA, while genes are specific segments of DNA that provide instructions for a particular trait. Chromosomes house many genes, along with other DNA sequences, and are inherited in pairs, one from each parent. Genes determine specific traits, such as eye color or blood type.
