"Chromosome" Natural Recordings by Native Speakers
A chromosome is a thread-like structure made up of DNA and proteins that carries genetic information in the nucleus of living cells. It is made up of a long double helix of DNA wrapped around proteins called histones, and plays a central role in the development and function of all living organisms. In humans, there are 23 pairs of chromosomes, for a total of 46 chromosomes, in every cell of the body. Each chromosome has a specific set of genes that determine the characteristics of an individual.
A chromoplast is a type of plastid found in plants, particularly in flowers, fruits, and leaves. It is responsible for producing and storing pigments, such as carotenoids, anthocyanins, and betalains, which give plants their vibrant colors. Chromoplasts are different from chloroplasts, which photosynthesize and produce energy for the plant.
