Homologous chromosomes are chromosomes which contain the same genes in the same order along their chromosomal arms. There are two main properties of homologous chromosomes: the length of chromosomal arms and the placement of the centromere.
What is chromosomes that are the same size and have the same genes at the same locations?
The two chromosomes in a homologous pair are very similar to one another and have the same size and shape. Most importantly, they carry the same type of genetic information: that is, they have the same genes in the same locations.
How many genes are in a chromosome?
Chromosome 1 likely contains 2,000 to 2,100 genes that provide instructions for making proteins.
What is the main difference between Chromatin and chromosomes?
Chromatin is a complex formed by histones packaging the DNA double helix. Chromosomes are structures of proteins and nucleic acids found in the living cells and carry genetic material. Chromatin is composed of nucleosomes. Chromosomes are composed of condensed chromatin fibers.
What is a chromosome real life example?
Frequency: The definition of a chromosome is a thread-like structure of DNA (nucleic acids and proteins) that carries genes. The “X” or “Y” gene that determines whether you will be a boy or a girl is an example of a chromosome.
What is difference between gene and DNA?
In general, a gene is a short section of DNA and DNA- Deoxyribonucleic acid is a molecule which carries the genetic instructions or the hereditary materials.
DNA- Deoxyribonucleic acid.
