Answer: These 2 are called the double helix made up of sugar and phosphate groups. Attached to each sugar is one of four bases--adenine, cytosine, guanine, and thymine.
Atomic number=protons=neutrons or, A-P-E. So, an element like this doesn't exist because protons and electrons have the same number.
The answer is D a nucleosome; a nucleosome has DNA wrapped around histones which prevents chromatin from tangling :)
The efficiency of genetic transformation of intact Saccharomyces cerevisiae cells rose to more than 1 105 transformants per microgram of vector DNA and to 1.5% transformants per viable cell utilising a method that produces competent cells using LiAc.
<h3>What is nucleic acids ?</h3>
Biopolymers and macromolecules called nucleic acids are necessary for all known forms of life. They are constructed of monomers called nucleotides, which are composed of a nitrogenous base, a phosphate group, and a 5-carbon sugar. Deoxyribonucleic acid and ribonucleic acid are the two primary types of nucleic acids.
- Gene expression, cellular activity regulation, genetic information storage and transfer are the three primary uses of nucleic acids.
