Best answer: What is the best definition of homologous chromosomes?

Homologous chromosomes are two pieces of DNA within a diploid organism which carry the same genes, one from each parental source. In simpler terms, both of your parents provide a complete genome. Each parent provides the same 23 chromosomes, which encode the same genes.

What is homologous chromosomes?

Homologous chromosomes: A pair of chromosomes that contain the same gene sequences, each derived from one parent.

What is the best definition of a chromosome?

(KROH-muh-some) A structure found inside the nucleus of a cell. A chromosome is made up of proteins and DNA organized into genes. Each cell normally contains 23 pairs of chromosomes.

What is meant by homologous chromosomes quizlet?

Homologous chromosomes are chromosome pairs, one from each parent, that are similar in length, gene position and centromere location. … Each carries the same genes in the same order, but the alleles for each trait may not be the same.

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 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.

Which are the two main parts that make up a chromosome?

DNA is coiled around proteins called histones, which provide the structural support. Chromosomes help ensure that DNA is replicated and distributed appropriately during cell division. Each chromosome has a centromere, which divides the chromosome into two sections – the p (short) arm and the q (long) arm.

What is the main function of a chromosome?

The most important function of chromosomes is to carry the basic genetic material – DNA. DNA provides genetic information for various cellular functions. These functions are essential for growth, survival, and reproduction of the organisms. Histones and other proteins cover the Chromosomes.
