How does the structure of DNA differ from that of RNA? Explain how you could use the nucleic acid sequence of RNA for a protein to trace evolutionary relationships between organisms. Describe all of the differences between DNA and RNA.
How did the discovery of the enzyme DNA polymerase play in the understanding for the process of DNA replication? What is RNA Polymerase? How does it help protein synthesis? Relating to biology, explain the term 'RNA polymerases'. Explain how DNA codes for traits. (Disc...
Distinguish DNA from RNA, what is the same, what is different? Importance in function? What does DNA stand for? What is the difference between DNA and RNA? What are the three types of RNA? How do they differ from each other? What is the difference between DNA and RNA from a biological...
DNA is a long molecule. For example, a typical bacterium, likeE. coli, has one DNA molecule with about 3,000 genes. If drawn out, this DNA molecule would be about 1 millimeter long. However, a typicalE. coliis only 3 microns long (3 one-thousandths of a millimeter). So to fit ins...
How does the DNA hold a code that affects your traits? DNA Basics DNA is found in the cells of all organisms, including plants, bacteria, mosquitoes and humans. Each organism has a unique set of DNA, but DNA functions the same way in all organisms ...

Mutations can introduce traits that are completely new and have never appeared in that species before. Sexual reproduction mixes the genes of each parent by splitting, breaking and blending chromosomes (the strands that contain DNA) during the creation of each sperm and egg. When the sperm and ...
How does water affect DNA structure? Structure of DNA: DNA is composed of two antiparallel strands of nucleic acids that are held together by hydrogen bonds between the nitrogenous bases of opposing strands. The backbone of each strand of DNA is composed of alternating phosphate and deoxyribose mo...
How does CRISPR edit DNA? Who discovered CRISPR? How has CRISPR been used? What are potential risks of CRISPR? CRISPR, short for CRISPR-Cas9, is a genome-editing tool that allows scientists to precisely cut and modify DNA sequences. It has revolutionized the study of genes, helped to...
things, including humans. The genome is the complete set of genes present in an organism. It contains all hereditary traits and determines what physical and behavioral features an organism will have. About 20,000 genes make up a genome, which is comprised of DNA sequences that code for ...
