What make up a nucleotide?
A nucleotide is a molecule which consists of a nitrgenous base and a phosphate group attatched to the C1 and C4 position of pentose sugar(beta-2-Deoxyribose) respectively.It is a monomer of nucliec acid.
What is the meaning of the letters DNA in biochemistry?
DNA stands for deoxyribonucleic acid. The NA refers to the basic variety of molecule DNA is - a nucleic acid. Nucleic acids are polymers of nucleotides, a nucleotide consisting of a nitrogenous base, a pentose sugar, and a phosphate group. The D comes from deoxyribose - the specific name of the sugar in DNA. It's similar to the ribose in RNA but a hydroxyl group has been removed from the 2' position - hence "deoxy"-ribose.
The structure of RNA is different from DNA because it contains the sugar deoxyride?
RNA contains the sugar ribose in its sugar phosphate backbone while DNA contains deoxyribose in its sugar phosphate backbone. Deoxyribose differs from ribose in that deoxyribose lacks a hydroxyl group (OH) in its 2' position while ribose does not. Also, RNA contains the nucleotide Uracil and DNA contains the nucleotide Thymine. Uracil is just a methylated thymine, the importance of this difference is that the nucleotide Cytosine can easily convert to Uracil while it can't convert to Thymine. This helps to maintain the integrity of the information encoded by DNA and also makes for easier repair in DNA if an error is encountered during replication. Lastly, DNA is a double helix of two strands oriented in a right hand twisted fashion while RNA is a single stranded molecule that is transcribed from DNA.
What is the probability of any nucleotide being present at any position in a molecule of DNA?

What molecules make up a nucleotide and hence are the building blocks for the DNA molecule?
There are four nucleotides made up of: 1. Deoxiribose sugar - there are 5 carbons, numbered 1-5 (prime) beginning to the right of the O (at the 1:00 position). 2. 1 PO4(phosphate group) - always attached to the 5 prime carbon. 3. 1 of 4 Nitrogenous Bases - Adenine (A), Guanine (G), Thymine (T), Cytosine (C). Bases are always attached to the 1 prime carbon.

What are the three parts of RNA?
Ribose sugar, base and phosphate groupEach nucleotide in RNA contains a ribose sugar, with carbons numbered 1' through 5'.A base is attached to the 1' position, in general, adenine (A), cytosine (C), guanine (G), or uracil (U). Adenine and guanine are purines, cytosine, and uracil are pyrimidines.A phosphate group is attached to the 3' position of one ribose and the 5' position of the next. The phosphate groups have a negative charge each at physiological pH, making RNA a charged molecule (polyanion).

Why is it important for the nucleotide bases to stay in the same position?
It is important for nucleotide bases to stay in the same position because they provide the genetic information necessary for the functioning of an organism. The arrangement of the bases in the DNA molecule determines the sequence of amino acids in proteins, which play crucial roles in cellular processes. Any change in the position of the nucleotide bases can lead to disruptions in these processes, potentially causing genetic disorders or functional abnormalities.
What is a codon made of?
A codon is made up of a sequence of three nucleotides. In DNA, a nucleotide contains the sugar deoxyribose, a phosphate group, and one of four nitrogen bases; adenine, thymine, guanine, and cytosine. In RNA, a nucleotide contains the sugar ribose, a phosphate group, and one of four nitrogen bases; adenine, uracil, guanine, and cytosine. Each codon represents an amino acid, or a start or stop signal.
Is there any distinction between biphosphate and diphosphate?
biphosphate refers to two phosphate monoesters attached to one central molecule, whereas diphosphate refers to two phosphate monoesters attached to the SAME POSITION of one central moelecule.
Why do some mutations not affect the amino acid sequnce of a protein?
When the nucleotide in 3rd position of codon is change it does not change the aminoacid and is called point or silent mutation.
The process of glycogen to glucose?
Glycogen is a highly branched polymeric structure containing glucose as the basic monomer. First individual glucose molecules are hydrolyzed from the chain, followed by the addition of a phosphate group at C-1. In the next step the phosphate is moved to the C-6 position to give glucose 6-phosphate, a cross road compound. Glucose-6-phosphate is the first step of the glycolysis pathway if glycogen is the carbohydrate source and further energy is needed. If energy is not immediately needed, the glucose-6-phosphate is converted to glucose for distribution in the blood to various cells such as brain cells.
The Human Genome Project was created to count what?
Not to count, it is to analyse the sequence of Human DNA. Approximately 3x1000000000 basepairs are making human genome. This project studies the sequence or position of nucleotide bases of DNA molecule.
