What does DNA ligase do? What is the structure of DNA? What are DNA repair genes? What do DNA repair genes do? What is branched DNA? What are the bases that make up DNA? Which base is found only in DNA? What is the chemical bond responsible for DNA structure?
What is the sugar found in an RNA nucleotide? Explain how both nucleic acids and proteins are polymers? Which amino acids are hydrophobic? What is a nucleotide analog? What molecules make up single-stranded DNA? Which nucleic acid moves the code for protein synthesis from the nucleus to the ...
The nucleus directs all activities that occur within the cell and also contains the cell’s genetic material, or DNA.The nucleus gives the signal to the cell to grow, divide or make proteins. A nuclear envelope surrounds the nucleus, allowing only certain substances to enter and exit. The n...
A nucleon is a collective term for protons and neutrons inside an atomic nucleus, while the nucleus is the core of an atom, containing nucleons and thus most of the atom's mass.
The Nucleus: In eukaryotic cells, the nucleus holds the DNA. DNA is arranged in long strands, each being called a chromosome. The normal human nucleus has 46 chromosomes. These chromosomes are identical in each cell, thanks to the process of cell division. ...
What’s in the Nucleus? Genetic material Helix Found in the nucleus Contains the directions for making proteins Passed from one generation to the next DNA (deoxyribonucleic acid) Helix A coil that has a constant diameter Double helix A coil made up of two strands, each of which is a helix...
What Is DNA? Deoxyribonucleic acid (DNA) is an organic molecule found in the nucleus of cells. It contains the genetic instructions for all living organisms. DNA is the molecule that encodes genetic information in cells and is made up of adenine, cytosine, thymine, and guanine. DNA molecules...
and each nucleotide has a compound of phosphate sugar which is the backbone, and a sugar deoxyribose. The Phosphates and sugars are the same in all nucleotides but the one thing that is different would be the bases.DNAbases are cytosine, thymine, adenine, and guanine. Each base has specific...
Packaging of DNA into the cell nucleus (Photo Credit : Designua/Shutterstock) What Does DNA Do? DNA is like a set of instructions that govern the arrangement of amino acids. It is composed of various 3 letter codes, calledcodons. These codons need to be interpreted in order to attain the...
In this lesson on RNA, see the ribonucleotide definition, learn what RNA does, why RNA is important, what RNA is made of, and see RNA types and...
