Ribonucleic acid (RNA) molecules may be best known for their job ferrying the genetic information encoded in DNA to a cell's ...

However, in the half-century since the structure of DNA was first elaborated, scientists have learned that RNA does much more than simply play a role in protein synthesis. For example, many types ...

When RNA molecules are synthesized by cells—a critical process in the creation of proteins and other cellular functions—they ...

Ribonucleic acid (RNA) is a linear molecule composed of four types of smaller molecules called ribonucleotide bases: adenine (A), cytosine (C), guanine (G), and uracil (U). RNA is often compared ...

This process of protein synthesis occurs in two stages - transcription and translation. When a gene is to be expressed, the base sequence of DNA is copied or transcribed into mRNA (messenger RNA).

For discussion questions and lesson plans, go to the RNA Lab collection on PBS LearningMedia. The standards-based NOVA RNA Lab allows users to explore the science of RNA and learn how to design ...

The rRNA structures also provide binding sites for ribosomal proteins, which help stabilize the overall structure of ... amino acids during protein synthesis. This discovery led to the concept of the ...

RNA is similar to DNA but contains uracil instead of thymine ... the cellular machinery responsible for protein synthesis. rRNA molecules, along with ribosomal proteins, form the structure of the ...

The DNA blueprint ... of the messenger RNA transcript by assembling amino acids into the corresponding polypeptide sequence. Ribosomal functions beyond protein synthesis have been uncovered ...

This includes protein structure and function, metabolism, and the mechanics of DNA, RNA, and protein synthesis. Our program serves students pursuing a bachelor of science or arts degree, as well as ...
