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 ...
Understanding the structure and function of RNA is important to a fundamental knowledge of genetics; in addition, many developing medical therapies will undoubtedly utilize special RNAs to combat ...
Start studying Structure & Function of DNA and RNA. Learn vocabulary, terms, and more with flashcards, games, and other study tools.
RNA Structure and Function. Ribonucleic acid (RNA) also consists of nucleotides, but these nucleotides contain the sugar ribose. RNA has A,C,G and U. Although both RNA and DNA are nucleic acids, there are key differences in the structure and function of RNA and DNA. There are three types of RNA and each is involved in protein synthesis.
RNA: RNA, complex compound of high molecular weight that functions in cellular protein synthesis and replaces DNA as a carrier of genetic codes in some viruses. RNA consists of ribose nucleotides and the nitrogenous bases adenine, guanine, cytosine, and uracil. Learn about the structure, types, and functions of RNA.
The chemical structure of RNA is very similar to that of DNA, but differs in three primary ways: . Unlike double-stranded DNA, RNA is a single-stranded molecule in many of its biological roles and consists of much shorter chains of nucleotides. However, a single RNA molecule can, by complementary base pairing, form intrastrand double helixes, as in tRNA.
Ribosomal RNA - The Protein Factories: Most of the RNA in cells is part of the structure of small cellular organelles known as ribosomes, the protein factories of the cells. Messenger RNA - The Genetic Blueprint: Messenger RNA is a copy of the genetic information that was transcribed from the cell’s original blueprint, DNA.
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 the four nitrogenous bases (A, U, G, and C), and a phosphate group.
This presentation of 42 slides delivers information about structure,function synthesis , life span of both prokaryotic and eukaryotic messenger RNA also about role in protein sorting and targetting
Ribonucleic acid (RNA) is one of two key nucleic acids, the other being DNA. Messenger RNA (mRNA) is transcribed from DNA in the nucleus before heading into the cytoplasm and attaching itself to ribosomes to take part in translation, which is the synthesis of proteins from amino acids.
