What is the structure of an RNA molecule?

What is the structure of an RNA molecule?

RNA consists of ribose nucleotides (nitrogenous bases appended to a ribose sugar) attached by phosphodiester bonds, forming strands of varying lengths. The nitrogenous bases in RNA are adenine, guanine, cytosine, and uracil, which replaces thymine in DNA.

Which of the following statements best describes the function of RNA?

Functions of RNA: It serves as a structural component for ribosomes (ribosomal RNA), and it has a role in protein synthesis (messenger RNA transfer RNA).

What is the structure of RNA quizlet?

What is the structure of RNA? Single-stranded. Like DNA, RNA is composed of its phosphate group, five-carbon sugar (the less stable ribose), and four nitrogen-containing nucleobases: adenine, uracil (not thymine), guanine, and cytosine. You just studied 28 terms!

What is the structure of RNA and DNA?

Three main types of RNA are involved in protein synthesis. They are messenger RNA (mRNA), transfer RNA (tRNA), and ribosomal RNA (rRNA). rRNA forms ribosomes, which are essential in protein synthesis. A ribosome contains a large and small ribosomal subunit.

Which of the following statements best describes the structure of RNA?

Which of the following statements best describes the structure of RNA molecules in general? RNA molecules form a double helix modeled after the DNA from which they are encoded. RNA molecules are single stranded but they commonly form localized secondary structures by base pairing between regions of the molecule.

What is the function of RNA * Your answer?

There are two main functions of RNA. It assists DNA by serving as a messenger to relay the proper genetic information to countless numbers of ribosomes in your body, with ribosomes being the small protein-creating factories located inside of a cell.

What is the structure of the RNA?

RNA consists of ribose nucleotides (nitrogenous bases appended to a ribose sugar) attached by phosphodiester bonds, forming strands of varying lengths. The nitrogenous bases in RNA are adenine, guanine, cytosine, and uracil, which replaces thymine in DNA.

What is the main function of RNA?

The central dogma of molecular biology suggests that the primary role of RNA is to convert the information stored in DNA into proteins.

What is the main function and types of RNA?

FUNCTIONS OF RNA Messenger RNA (mRNA) copies DNA in the nucleus and carries the info to the ribosomes (in cytoplasm). Ribosomal RNA (rRNA) makes up a large part of the ribosome; reads and decodes mRNA. Transfer RNA (tRNA) carries amino acids to the ribosome where they are joined to form proteins.

What are structural or functional characteristics of RNA?

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.

What is the structure of RNA?

RNA consists of ribose nucleotides (nitrogenous bases appended to a ribose sugar) attached by phosphodiester bonds, forming strands of varying lengths. The nitrogenous bases in RNA are adenine, guanine, cytosine, and uracil, which replaces thymine in DNA.

What are the structures of RNA?

RNA consists of four nitrogenous bases: adenine, cytosine, uracil, and guanine. Uracil is a pyrimidine that is structurally similar to the thymine, another pyrimidine that is found in DNA.

What are the 3 parts of an RNA molecule?

Just like in DNA, RNA is made of monomers called nucleotides. Each nucleotide is made up of three components: a nitrogenous base, a pentose (five-carbon) sugar called ribose, and a phosphate group

What are the 3 types of RNA and their functions?

There are three types of RNA: mRNA, tRNA, and rRNA. mRNA is the intermediary between the nucleus, where the DNA lives, and the cytoplasm, where proteins are made. rRNA and tRNA are involved in protein synthesis. Additional RNAs are involved in gene regulation and mRNA degradation.

What are the 3 sites on the RNA?

The 3 binding sites for tRNA are called aminoacyl site (abbreviated A), the peptidyl site (abbreviated P) and the exit site (abbreviated E), which are oriented 5′ to 3′ E-P-A with respect to the mRNA. The A site binds to the incoming aminoacyl tRNA, which carries the new amino acid to be added to the polypeptide chain.

How is the structure of DNA and RNA the same?

RNA consists of ribose nucleotides (nitrogenous bases appended to a ribose sugar) attached by phosphodiester bonds, forming strands of varying lengths. The nitrogenous bases in RNA are adenine, guanine, cytosine, and uracil, which replaces thymine in DNA.

What is the structure of DNA and RNA quizlet?

Despite their different jobs, DNA and RNA have almost the same basic structure. DNA uses deoxyribose, but RNA uses ribose, which has an extra hydroxyl group (OHu2212) tacked on. DNA and RNA also have nearly identical nitrogenous bases. Both have the bases adenine, cytosine, and guanine.

What is the main structure of DNA?

DNA is double-stranded, RNA is single-stranded. – DNA contains a pentose sugar Deoxyribose, RNA contains the pentose sugar Ribose. A pentose is a 5-carbon sugar molecule. – DNA is limited to the nucleus, RNA is made in the nucleus, but can travel outs

What are the three functions of RNA?

mRNA, rRNA, and tRNA are the three main types of RNA involved in protein synthesis. RNA also serves as the primary genetic material for viruses. Other functions include RNA editing, gene regulation, and RNA interference

What is the structure RNA?

Functions of RNA: It serves as a structural component for ribosomes (ribosomal RNA), and it has a role in protein synthesis (messenger RNA transfer RNA).

Which of the given statements is true about RNA?

Ribonucleic acid (RNA) is a molecule similar to DNA. Unlike DNA, RNA is single-stranded. An RNA strand has a backbone made of alternating sugar (ribose) and phosphate groups. Attached to each sugar is one of four bases–adenine (A), uracil (U), cytosine (C), or guanine (G).
