All genomes, except for viral genomes, are comprised of these nucleic acids. Under normal conditions, DNA exists as a double-stranded molecule in the form of a helix, essentially a ladder. So, it is also known as the Watson and Crick model.

Each DNA strand is made up of a sugar phosphate backbone. The linkers or steps of the ladder, consist of intricately bound pair of nucleotides. There are four nucleotides or nucleic acid molecules in DNA. Adenine A and Guanine G are the two purines, containing two carbon-nitrogen rings one being an imidazole ring.

Basic Chemistry for Biology, Part 1: Atoms

Cytosine C and Thymine T are the two pyrimidines, containing one carbon-nitrogen ring structure. Depending on the base composition, there can form 5 different types of nucleotide triphosphates, which covalently bind with each other by phosphodiester bond formation to give rise to the polynucleotides, namely- Deoxyribonucleic acid DNA and Ribonucleic acid RNA. It is a rule that adenine always pairs up thymine or uracil in case of RNAand guanine interacts with cytosine; Two hydrogen bonds are formed between adenine and thymine, while guanine and cytosine interact by three hydrogen bond formation.

According to Chargaff's rule, the number of purines in a given DNA is always equal to the number of pyrimidines. It is a gene that encodes a coherent set of amino acids specific for a particular polypeptide chain. The interaction of genes with each other and with environmental factors results in the physical development and observable characteristics phenotype of an organism.If you're seeing this message, it means we're having trouble loading external resources on our website.

Chemistry Did you know that everything is made out of chemicals? Chemistry is the study of matter: its composition, properties, and reactivity. This material roughly covers a first-year high school or college course, and a good understanding of algebra is helpful.Students who have studied in Chemistry In Biology would find it a little difficult to understand the topic of the workbook.

The chapters are split into five sections, each section has ten topics to cover. Therefore, it is not that easy to keep track of all the topics as you have more than ten topics to go through at a time. This has made the studying process a little bit tricky for most students. However, there are always ways on how you can make the process of Chemistry In Biology easier for you.

Students should be able to learn and master the topics in the study guides. The topics in the books will help students learn more about their subject matter.

However, sometimes, these topics will confuse the students too much. This is why the information on the books can only serve as the guideline in the learning process. If you have been having problems in the past with the above-mentioned topics, you can always use the various worksheets that are provided with the Chemistry In Biology.
