What is common to all RNA molecules?
Although there are multiple types of RNA molecules, the basic structure of all RNA is similar. Like DNA, each RNA strand has the same basic structure, composed of nitrogenous bases covalently bound to a sugar-phosphate backbone (Figure 1). However, unlike DNA, RNA is usually a single-stranded molecule.
What are the 3 parts of an RNA molecule?
RNA nucleotides, like those from DNA, have three parts: a 5-carbon sugar, a phosphate group and a base.
What 4 monomers make up A RNA molecule?
Explanation: Nucleotides are monomers of both DNA and RNA . However, nucleotides themselves are made up of many other molecules. A nucleotide is made up of a 5 -carbon sugar, a nitrogenous base (adenine, guanine, cytosine, thymine, or uracil), and a phosphate group (PO3−4) .
How many types of RNA molecules are there?
Three main types of RNA are involved in protein synthesis. They are messenger RNA (mRNA), transfer RNA (tRNA), and ribosomal RNA (rRNA).
What is synthetic RNA made of?
A nucleic acid present in all living cells and many viruses, consisting of a long, usually single-stranded chain of alternating phosphate and ribose units, with one of the bases adenine, guanine, cytosine, or uracil bonded to each ribose molecule.
What is an RNA molecule?
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).
What two molecules make up nucleic acids?
The two main classes of nucleic acids are deoxyribonucleic acid (DNA) and ribonucleic acid (RNA). DNA is the master blueprint for life and constitutes the genetic material in all free-living organisms and most viruses.
How many strands make up DNA?
The DNA molecule consists of two strands that wind around one another to form a shape known as a double helix. Each strand has a backbone made of alternating sugar (deoxyribose) and phosphate groups.
Is cytosine A pyrimidine?
cytosine, a nitrogenous base derived from pyrimidine that occurs in nucleic acids, the heredity-controlling components of all living cells, and in some coenzymes, substances that act in conjunction with enzymes in chemical reactions in the body.
What are all polymers made up of?
A polymer is made up of a number of joined-together monomers. One way of thinking about polymers is like a chain of connected-up paperclips. A polymer is a large molecule made up of smaller, joined-together molecules called monomers.
What are RNA molecules?
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). Unlike DNA, RNA is usually single-stranded.
