1. The DNA unzips like it did during DNA replication. One strand of DNA is "transcribed" or "copied" to make a messenger RNA (mRNA) molecule. The nitrogenous bases pair up. Uracil is now paired up with adenine for RNA. 2. Once the mRNA has transcribed the message, it breaks away from the DNA strand. The DNA then "rezips" back to its double ...
Hydrogen bonds are weak, however, when you have hundreds or thousands of them in a row, it makes a more stable structure. Nevertheless, you don't want the bonds too be too strong, otherwise it would cost way too much energy to unwind DNA for replication and transcription.

The key difference between DNA and RNA structure is that the DNA structure is a double helix composed of two complementary strands while the RNA structure is single-stranded. Also, deoxyribonucleotide is the basic unit of DNA while ribonucleotide is the basic unit of RNA. DNA contains thymine while RNA contains uracil

DNA, or deoxyribonucleic acid, is like a blueprint of biological guidelines that a living organism must follow to exist and remain functional. RNA, or ribonucleic acid, helps carry out this blueprint's guidelines. Of the two, RNA is more versatile than DNA, capable of performing numerous, diverse ...

RNA molecules perform a variety of roles in the cell but are mainly involved in the process of protein synthesis (translation) and its regulation. RNA Structure. RNA is typically single stranded and is made of ribonucleotides that are linked by phosphodiester bonds. A ribonucleotide in the RNA chain contains ribose (the pentose sugar), one of ...
