核酸(nucleic acid)分成两种,脱氧核糖核苷酸(deoxyribonucleic acid,DNA)和核糖核苷酸(ribonucleic acid,RNA)。DNA主要存在于细胞核中的染色体上,RNA主要存在于细胞质中,有少部分在核内。 Nucleotides 2.6.U1 The nucleic acids DNA and RNA are polymers of nucleotides. 2.6.S1 Drawing simple diagrams of the struc...
RNA Structure Continued… D. May leave the nucleus, unlike DNA E. Three types of RNA: ribosomal RNA (rRNA) makes up the ribosome transfer RNA (tRNA) brings amino acids to the ribosome to make a protein 3. messenger RNA (mRNA) carries DNA message out of the nucleus and ...
Structure and Function of DNA and RNA Deoxyribonucleic acid (DNA) is a nucleic acid that contains the genetic instructions for the development and function of organisms. All known cellular life and some viruses contain DNA. The main role of DNA in cells is to store information for long periods...

DNA vs RNA Both are Nucleic Acids DNA has sugar Deoxyribose / RNA has sugar Ribose DNA has bases A, T, C, G / RNA has bases A, U, C, G DNA is always in the nucleus / RNA goes from nucleus to ribosomes DNA has 2 strands (double helix) / RNA has 1 strand ...
RNA have typically been considered as functionally distinct from proteins that bind DNA and studied independently. This practice is becoming outdated, in partly owing to the discovery of long non-coding RNAs (lncRNAs) that target DNA-binding proteins. Consequently, DRBPs were found to regulate many...
cells and many viruses. It consists of two strands of nucleotides linked together in a structure resembling a ladder twisted into a spiral. In eukaryotic cells, the DNA is contained mainly in the nucleus and mitochondria. DNA can replicate itself and synthesize RNA. CompareRNA. See Note atgene...

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 uraci
The mRNA carries the message from the DNA, which controls all of the cellular activities in a cell. If a cell requires a certain protein to be synthesized, the gene for this product is “turned on” and the mRNA is synthesized through the process oftranscription(seeRNA Transcription). The ...
