Complementary strands. (Science: molecular biology) two single strands of dna in which the nucleotide Sequence is such that they will bind as a result of base pairing throughout their full length.

While DNA has the ATCG nitrogenous bases, RNA replaces thymine with uracil, making its bases AUCG. So, that means that whenever DNA has adenine, instead of pairing this with thymine, RNA will use uracil instead.

Complementary sequence: Nucleic acid sequence of bases that can form a double- stranded structure by matching base pairs. For example, the complementary sequence to C-A-T-G (where each letter stands for one of the bases in DNA) is G-T-A-C.

5′ CAGTCAAGCAT 3′ is the answer.

The nitrogen bases are held together by hydrogen bonds: adenine and thymine form two hydrogen bonds; cytosine and guanine form three hydrogen bonds.

two types

The backbone of each DNA strand is made of sugar residues that are held together with phosphodiester bonds.

The inside of the molecule, the “steps” of the staircase, are made of the nucleotide bases Cytosine, Guanine, Adenine, and Thymine. C bonds to G by three hydrogen bonds. A bonds to T by two hydrogen bonds. A and G are double ringed structures called “purines”.

DNA, which stands for deoxyribonucleic acid, resembles a long, spiraling ladder. It consists of just a few kinds of atoms: carbon, hydrogen, oxygen, nitrogen, and phosphorus. Combinations of these atoms form the sugar-phosphate backbone of the DNA — the sides of the ladder, in other words.

Proteins, carbohydrates, lipids, ATP, and nucleic acids.

Types of biological macromolecules

There are six main elements that are the fundamental building blocks of life. They are, in order of least to most common: sulfur, phosphorous, oxygen, nitrogen, carbon, and hydrogen. The basis of life is carbon.

Life is built with three major components: RNA and DNA — the genetic code that, like construction managers, program how to run and reproduce cells — and proteins, the workers that carry out their instructions.

Scientists once thought the most fundamental building block of matter was a particle called the atom. Now we know that the atom is made of many smaller pieces, known as subatomic particles. Every atom contains a central core called the nucleus, made of particles called protons and neutrons.

A cell is the smallest unit of life, also called the ‘building blocks of life’ because cells multiply and differentiate to form a multicellular organism as well as give rise to new organism by forming gametes or reproductive spores.
