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
Its full form isRibonucleic acid. This is a polymer of subunits joined by phosphodiester bonds. It is a single-stranded nucleic acid similar to DNA but having ribose sugar rather than deoxyribose sugar and uracil instead of thymine as one of the nucleotide bases. Figure: Types of RNA. Image ...
RNA nucleotides carry the nitrogenous bases, Purines, and Pyrimidines. But in RNA in place of Pyrimidine Thymine, Uracil is present which too forms hydrogen bonding with Adenine just as Thymine does in DNA molecule. Structure of RNA Structure of RNA. Created with BioRender.com RNA is a typica...
How can just four nitrogenous bases, i.e., adenine, cytosine, guanine, and uracil possibly code for all 20 amino acids? What are the five structural differences between DNA and RNA? Nucleotides are made up of what three subunits? What is RNA and DNA (in biology)?
RNA’s bases have adenine, guanine, uracil, cytosine; DNA is a form of a double helix, but RNA has no helix. 相关知识点: 试题来源: 解析 答:1, DNA,RNA 2, 核苷酸。3, DNA 是主要的遗传物质,RNA携带DNA的遗传信息并起蛋白质合成的模板作用4,DNA是脱氧核糖核酸,而RNA是核糖核酸;DNA通常是...
Life cycle, in biology, the series of changes that the members of a species undergo as they pass from the beginning of a given developmental stage to the inception of that same developmental stage in a subsequent generation. Learn more about life cycles.
RNA nitrogenous bases includeadenine (A),guanine (G),cytosine (C)anduracil (U). The five-carbon (pentose) sugar in RNA is ribose. RNA molecules arepolymersof nucleotides joined to one another by covalent bonds between the phosphate of one nucleotide and the sugar of another. These linkages ...
Genes can vary in their length and can be as long as a couple million bases. What are the different types of genes called? Different versions of the same gene are alleles. If the person has the same version of the gene they are termed as homozygous alleles, if they have different ...
RNA polymerases are enzymes catalyzing the synthesis of a strand of RNA. These polymerases can be RNA-dependent RNA polymerases that use RNA as their template and are found only in RNA viruses, or DNA-dependent RNA viruses that use DNA as their template and can be found in organisms ...
Sanger sequencing utilizes a chain-termination method to provide the identity and order of nucleotide bases in a given strand of DNA. This method makes use of chemical analogues of the four nucleotide bases. These analogues, called ddNTPs, are missing the hydroxyl group ...
