DNA, a fundamental building block of all life, from plants to animals and even viruses. DNA forms how we look, how cells function, and how genetic information is passed on by our parents. Answer and Explanation: The two strands in DNA are held together by hydrogen bonds that twist to for...
How does complementary base sharing ensure two identical daughter strands of DNA? Give the complementary base sequence for the following DNA strand. 5'-CGCGTTAGACTA-3' What are mutations and their impact on a DNA sequence? What is methylation and how does it cause an effect on gene expression...
What joins the two strands of the twisted ladder of DNA together? A. ester linkages B. peptide bonds C. covalent bonds D. hydrogen bonds E. none of the above DNA: DNA (Deoxyribonucleic acid) is an organic macrom...

DNA in a polymerase-driven reaction, strands of each possible length are produced when the ddNTPs are randomly incorporated and terminate the chain. The extension products are then separated by electrophoresis, resolved to single-nucleotide differences in size...
Double-stranded DNA is a molecule composed of two strands of DNA that twist around one another to form a double helix. The two strands are held together by hydrogen bonds that form between complementary base pairs of nucleotides (A pairs with T, and C with G) on each strand. If the ...
forms of life, alongside proteins, lipids, and complex carbohydrates (polysaccharides). As they are made up of smaller monomeric units called nucleotides, the two DNA strands are called polynucleotides. Each nucleotide is made up of a sugar called deoxyribose, a phosphate group, and one of four...
The chromosomes are very long thin strands of DNA, coiled up tightly. At one point along their length, each chromosome has a constriction, called the centromere. The centromere divides the chromosomes into two‘arms’: a long arm and a short arm. Chromosomes are numbered from 1 to 22 and ...

PCR works by repeatedly heating and cooling DNA. When DNA is heated, it separates into two single strands. Next, an enzyme called “Taq polymerase” is introduced to the sample. This enzyme synthesizes and uses the original DNA strands to “build” two new strands of DNA. Technicians can ...
