Whats a gene
5 answers
A gene is a segment of DNA (deoxyribonucleic acid) that encodes the instructions for building and functioning of a living organism. It is a unit of heredity that is passed down from parents to their offspring and carries the genetic information necessary for the development and functioning of an organism. Genes determine various characteristics or traits of an organism, such as its physical appearance, behavior, and susceptibility to certain diseases.
What structure carries information?
chromosome
nucleus
protein
centromere

centromere
The structure that carries information is the chromosome. Chromosomes are tightly coiled structures made up of DNA and proteins. They contain the genes that carry the genetic information needed for the development and functioning of an organism. The DNA sequence within the genes provides the instructions for building and maintaining the structures and functions of cells.
Which option contains all of the other options listed?
centromere
chromatid

chromosome
centromere
chromatid

chromosome
The correct answer is chromosome. A chromosome contains all of the other options listed within it.
- A chromosome is made up of two chromatids, which are identical copies of DNA that are held together by a centromere.
- Genes are segments of DNA that are found on chromosomes, carrying the instructions for building and maintaining an organism.
Therefore, a chromosome contains chromatids, genes, and a centromere, making it the option that encompasses all the others.
