Question

What is DNA and how does it work?

Answer 1

DNA is a molecule containing genetic instructions for the development, growth, and reproduction of organisms. Its structure is a double helix of nucleotides (A, T, C, and G) that determine genetic information passed from one generation to the next. DNA replication duplicates genetic information before cell division. Protein synthesis expresses DNA information through mRNA transcription and translation into amino acid sequences. DNA can influence gene expression through modifications to itself or the proteins interacting with it. DNA is essential for passing on genetic information and providing instructions for all living organisms.

Answer 2

DNA is a molecule that contains the biological instructions that distinguishes each species. During reproduction, DNA and the instruction it contains are hundred from adult organisms to their offspring.

Answer 3

DNA (Deoxyribonucleic Acid) is a molecule carrying genetic instructions. It consists of two strands forming a double helix, encoding genetic information. DNA replicates and serves as a template for protein synthesis, determining an organism's traits and functions.

Answer 4

DNA contains the instructions that an organism needs to grow, survive, and reproduce. To perform these tasks, DNA sequences must be converted into messages that can be used to make proteins, which are the complex molecules that do most of the work in our bodies.

Answer 5

DNA stands for Deoxyribonucleic Acid, and it is a molecule that contains the genetic instructions for the development, function and reproduction of all living organisms. It is found in the cells of all living organisms. The DNA molecule is made up of long chain of nucleotides, which are chemical building blocks. 

Answer 6

DNA (deoxyribonucleic acid) is a molecule that contains genetic information. It is found in the nucleus of cells and is responsible for the growth and development of living organisms. DNA works by providing instructions for proteins to be built and for cells to divide and replicate. It is made up of four different molecules, called nucleotides, that are arranged in a specific order.
