Therefore, the DNA nucleotide (Fig. 2.1 ) is composed of a 5-carbon sugar (called deoxyribose), a phosphate group, and a nitrogenous base (nitrogen-containing structure). Note the 5′-carbon (at the top) and the 3′-carbon (at the bottom) of the sugar. Fig.2.1 ......
DNA is a nucleotide that stands for deoxyribonucleic acid. DNA is the genetic code for all living things. Like other nucleotides, DNA is composed of a sugar, a nitrogenous base, and phosphate. Answer and Explanation: Learn more about this topic: ...
What is RNA made up of? And how they replicate themselves? What are the monomers of DNA and RNA called? They are composed of a sugar, a phosphate, and a nitrogenous base. How is double-stranded RNA formed? What is an RNA primer? Describe its role in DNA replication. ...
Step-by-Step Solution:1. Understanding DNA Structure: DNA (deoxyribonucleic acid) is composed of three main components: a sugar (deoxyribose), phosphate groups, and nitrogenous bases. 2. Identify
DNA is the molecule containing genetic information and on the basis of which proteins are synthesised. DNA is made from nucleotide monomers, each themselves made from a phosphate residue, a deoxyribose sugar and a nitrogenous base (either thymine, adenine, cytosine or guanine). ...
Nucleic acids are the organic materials present in all organisms in the form of DNA or RNA. These nucleic acids are formed by the combination of nitrogenous bases, sugar molecules and phosphate groups that are linked by different bonds in a series of sequences. The DNA structure defines the ...
With RNA, the sugar molecule is ribose, and the nucleosides are generally named without the 'deoxy' prefix. A complete nucleotide consists of a nitrogenous base, which is the pyrimidine or purine, a sugar molecule and a phosphate group. The phosphate group binds to the sugar molecule of a...
1. What are the four basic shapes of DNA? The four basic shapes of DNA are A-DNA, B-DNA, Z-DNA, and C-DNA. These shapes are determined by the arrangement of the sugar-phosphate backbone and the nitrogenous bases. 2. Is there a "correct" or most common shape for DNA?
Double-stranded DNA consists of two polynucleotide chains whose nitrogenous bases are connected by hydrogen bonds. Within this arrangement, each strand mirrors the other as a result of the anti-parallel orientation of the sugar-phosphate backbones, as well as the complementary nature of the A-T ...
The phosphate of one nucleotide is covalently bound (a bond in which one or more pairs of electrons are shared by two atoms) to the sugar of the next nucleotide. The hydrogen bonds between phosphates cause the DNA strand to twist. The nitrogenous bases point inward on the ladder and form ...
