- A nucleic acid that carries the genetic information in the cell and is capable of self-replication and synthesis of RNA.
- DNA consists of two long chains of nucleotides twisted into a double helix and joined by hydrogen bonds between the complementary bases adenine and thymine or cytosine and guanine.
- The sequence of nucleotides determines individual hereditary characteristics.

ProfessorDNA is an acronym for deoxyribonucleic acid. It is one of the two biologically significant nucleic acids, and of course serves as the information coding for each gene in an organism's genome. It is composed of three different molecules: a 5-membered sugar (deoxyribose), a phosphate group, and four different nitrogenous bases (adenine, guanine, thymine, or cytosine). The sequence of the nitrogenous bases along the DNA molecule is what produces the information in each gene.

What assembles short sequences of DNA?
Polymerase chain reaction (PCR) is a common method used to assemble short sequences of DNA. PCR requires a DNA template, primers (short DNA sequences that flank the target region), DNA polymerase enzyme, nucleotides, and a thermal cycler to amplify the DNA target region through repeated cycles of denaturation, annealing, and extension.
What is a short thick coil of DNA?
A short, thick coil of DNA is called a nucleosome. Nucleosomes are composed of DNA wrapped around histone proteins, forming a compact structure that helps regulate gene expression and protect the DNA molecule.
What is a short section of DNA called?
Genes
What is semidiscontinuous DNA means?
Semidiscontinuous DNA is a lagging strand synthesis. It is a short fragment in the structure of double helix.
A short stretch of DNA that can be distinuished from other molecules due to radioisotope labeling is a a gene library b DNA sequencer c probe d DNA fingerprint?
c) probe. A probe is a short stretch of DNA labeled with a radioisotope or fluorescent marker that is used to identify the presence of specific DNA sequences in a sample.
