What else can I help you with?
Are genes are made up of smaller molecules known as chromosomes?
Genes are segments of DNA, not smaller molecules like chromosomes. Chromosomes are long chains of DNA that contain multiple genes. Genes are specific sequences of DNA that encode information for making proteins, while chromosomes are structures that help organize and package the DNA in the cell.
Do chromosomes include DNA molecules histones and nuclosomes?
Yes, chromosomes are composed of DNA molecules wrapped around proteins called histones to form nucleosomes. Nucleosomes, the basic structural units of chromatin, help in compacting and organizing the DNA within the chromosome.
How many DNA molecules are in a chromosome just before mitiosis?
Just before mitosis, a chromosome consists of two sister chromatids joined by a centromere. Each sister chromatid contains one DNA molecule. Therefore, there are two DNA molecules in a chromosome just before mitosis.
What structures are in the nucleus that contains DNA?
The structures in the nucleus that contain DNA are chromosomes. DNA molecules are tightly wound around proteins called histones to form chromatin, which further condenses into chromosomes during cell division. These chromosomes carry the genetic information necessary for cell function and reproduction.
Is a chromosomes a DNA molecule?
Yes, chromosomes are made of DNA and protein molecules called histones. Edit from another user: False, they're made of material called chromatin. Edit from user #3: Chromosomes and chromatin are actually the same thing, except in different form. Both chromosomes and chromatin are made up of a strand of DNA wrapped around histone protein, except chromatin is in a long and stringy form while chromosomes are a compacted and twisted version of chromatin.
What molecules are found in chromosomes?
DNA molecules.
What DNA molecules are formed into structures?
Chromosomes
What is the relationship between chromosomes and DNA molecules?
Chromosomes are long strands of DNA molecules wrapped around proteins. DNA molecules are the genetic material that make up chromosomes and contain the instructions for the development, functioning, and reproduction of all living organisms. Chromosomes are organized structures that help to package and protect DNA within the cell.
What molecules make up chromosomes?
The DNA molecule.
Are genes are made up of smaller molecules known as chromosomes?

Does the size of a person affect their number of DNA?
No, the number of DNA molecules in a person is the same regardless of their size. Humans typically have 46 chromosomes, made up of long strands of DNA, in each cell. All the genetic information required for an individual is contained within these chromosomes.
Which molecules carry genetic information from one generation to the next?
They are DNA molecules. They are stored in chromosomes
In what ways is DNA unique among molecules?
The molecules of each DNA are exactly the same, they are aranged diferently within chromosomes though.
What molecule are the chromosomes made of?
Chromosomes are made up of DNA molecules. These DNA molecules are long strands composed of nucleotides, which are the building blocks of genetic information. The DNA in chromosomes is tightly packed and organized with proteins, forming a structure that is essential for cell division and storage of genetic information.
What best describes the relationship between chromosomes and DNA molecules?
Gene
