2022年5月20日 · What is the relationship and function of DNA, genes and chromosomes? DNA, genes and chromosomes work together to make you who you are. Chromosomes carry DNA in cells. DNA is responsible for building and maintaining your human structure. Genes are segments of your DNA, which give you physical characteristics that make you unique.

什么是dna ？ 严格意义上，dna才是人类以及几乎所有生命体的遗传物质。本质上，dna是由 腺嘌呤 （a）、 鸟嘌呤 （g）、 胞嘧啶 （c）及 胸腺嘧啶 （t）四种 脱氧核糖核酸 按照a与t配对，g与c配对的原则组合成的麻花一样的双链。我们人类的dna总共有约30亿对 ...

2024年8月22日 · Our genes are made up of DNA, a molecule with this coded information. Hundreds to thousands of genes are found on each chromosome inside our cells. Together, the DNA, genes, and chromosomes make up the complete set of genetic instructions for every individual—referred to as a genome.

DNA is the genetic material, which is involved in carrying the hereditary information, replication process, mutations, and also in the equal distribution of DNA during the cell division. The difference between DNA and gene are summarized below. Genes are the DNA stretches which encode for specific proteins. Regulates the traits of an organism.

2024年5月21日 · A gene is the basic physical and functional unit of heredity. Genes are made up of DNA. Some genes act as instructions to make molecules called proteins, which are needed for the body to function.

We define a gene as a DNA sequence that is transcribed. This definition includes genes that do not encode proteins (not all transcripts are messenger RNA). The definition normally excludes regions of the genome that control transcription but are not themselves transcribed.

The stringy stuff in the test tube is DNA. But you can't tell which one of these organisms it came from just by looking at it. That's because DNA looks exactly the same in every organism on Earth. All living things have DNA. And whether it comes from you, …

2020年8月24日 · Deoxyribonucleic acid (DNA) is a molecule that contains the biological instructions that make each species unique. DNA, along with the instructions it contains, is passed from adult organisms to their offspring during reproduction. Where is DNA found? In organisms called eukaryotes, DNA is found inside a special area of the cell called the nucleus.

2024年2月15日 · Purpose: DNA is a chemical that stores the genetic information of organisms and is designed for gene regulation. On the other hand, genes are DNA stretches encoded for specific proteins, copying unique traits, and supporting seamless inheritance.

2023年12月20日 · A gene is a specific segment of DNA that contains the instructions for making a specific protein, while DNA refers to the entire genetic material of an organism. How do genes and DNA relate to each other?
