Why is DNA called deoxyribonucleic acid and not ribonucleic acid? What is the purpose of DNA helicase? Why doesn't RNA form a double helix? What is the purpose of DNA ligase? Why is RNA important to the cell? Why does DNA synthesis require an RNA primer?
Deoxyribonucleic acid (DNA) is a polymer of deoxyribonucleotides. Each deoxyribonucleotide consists of a deoxyribose sugar, a nitrogen base, and a phosphate group. The nucleotides are linked by phosphodiester bonds.Answer and Explanation: The negative charge of DNA is due to the phosphate groups ...
问题:“基因”的主要功能是什么?联系原文:DNA is also called a “gene(基因)”. This is a very interesting thing. Genes are passed down from your parents. That is why you might have the same smile like your dad’s or mom’s!句意:DNA也被称为“基因”。这是一个非常有趣的事情。基因是...
Answer:Deoxyribonucleic acid– a large molecule of nucleic acid found in the nuclei, usually in the chromosomes, of living cells. DNA controls such functions as the production of protein molecules in the cell, and carries the template for reproduction of all the inherited characteristics of its pa...
In addition to some virus outside (if the virus is also beings), all creatures on earth with deoxyribonucleic acid (DNA) as genetic material; with the same four nucleotides to write life password; with 20 kinds of amino acids to the same protein composition are used to build biological ...
Deoxyribonucleic Acid A DNA nucleotide is made up of three parts 5 C Sugar-Deoxyribose Phosphate group Nitrogenous base The Shape of the Molecule DNA is a very long polymer. The basic shape is like a twisted ladder or zipper. This is called a double helix. ...
Deoxyribonucleic acid or DNA packaging is an efficient cellular process that significantly modifies the DNA structure to easily fit into the cellular nucleus. The DNA is typically long, and this modification must be adjusted as per the nucleus area. ...
DNA HP (hyper polymerised deoxyribonucleic acid), the marine-based ingredient that reduces fine lines and wrinkles, hydrates, protects, and regenerates skin.
The nucleus of the cell containsdeoxyribonucleic acid(DNA) – the "blueprint" of a living organism. Genes are snippets of DNA in the chromosomes that influence inheritable traits such as natural athletic ability. Different forms of genes are called alleles. Many possible types of alleles exist ...
Structure of DNA The units (monomers) that make a DNA molecule are called nucleotides. A single nucleotide is comprised of a deoxyribose sugar, phosphate molecule, and a nitrogenous base. There are four nitrogenous bases in DNA: adenine, thymine, guanine, and cytosine. ...
