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?
DNA is the molecule that genes are made of. Chromosomes are the (arbitrary) clumping that genes form in cells.
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.
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?
Are genes on DNA and DNA on chromosomes?
Yes, genes are segments of DNA located on chromosomes. Chromosomes are structures composed of DNA and proteins that carry the genetic information of an organism, including genes that provide instructions for protein synthesis and other cellular processes.
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.
What genes are DNA and chromosomes?
DNA is composed of genes, which are segments of DNA that code for specific traits or functions in an organism. Chromosomes are structures made up of tightly-coiled DNA and associated proteins, containing many genes organized along their length. Genes are the units of heredity carried on chromosomes that determine an organism's traits.
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.
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.
