Mengenal Gen, DNA, RNA, dan Kromosom | Biologi Kelas 12
网页2018年7月3日 · Gen adalah substansi pembawa materi genetik yang diwariskan dari induk kepada keturunanya. Materi genetik tersebut meliputi Deoxyribonucleic Acid (DNA) dan Ribonucleic Acid (RNA). DNA dan RNA ini jumlahnya ada banyak banget, lho! Berbagai jenis DNA bergabung untuk membentuk gen, kemudian gen-gen tersebut bergabung untuk membentuk kromosom.
What Are Genes, DNA, and Chromosomes? - Verywell Health
网页2024年8月22日 · Genes are comprised of DNA and are tasked with making specific proteins that play a critical role in the structure and function of the body. Chromosomes containing thousands of genes are passed from parents to offspring …

Genetics, Chromosomes - StatPearls - NCBI Bookshelf
网页2023年4月3日 · A chromosome is a DNA molecule that contains the genetic information for an organism. The chromosomal structure is composed of the organism's DNA and special proteins to form the dense, coiled architecture. The chromosome's tertiary structure is a crucial component in transcription regulation and cellular replication, and division.
DNA, chromosomes and gene expression - Science Learning Hub
网页Chromosomes are long thread-like structures made of a DNA molecule and protein. During cell division, chromosomes coil up tightly into X shapes and are more easily visible under a microscope. Human cells have 23 pairs of chromosomes.
