What DNA nucleotides bind together? What are the bonds that hold together the DNA backbone called? What protein unwinds and separates DNA strands in DNA replication? The two strands in DNA are antiparallel. What does this mean? What type of bonding between the A-T and G-C base pairs helps...
Nucleotides D. Phospholipids Once lipids are inside the absorptive cell of the small intestine: fatty acids and monoglycerides combine to form triglycerides, these triglyceride along with phospholipids and cholesterol are coated with proteins forming a structure known as? a. SGLT pr Which of the f...
What breaks the hydrogen bonds between mRNA and DNA? What is the basic unit of DNA packaging in chromatin? Is B-DNA double-stranded with antiparallel strands? What type of bond connects two complementary nucleotides? What is made during DNA replication?
Adenine and guanine are the purines and each one features a five membered and a six membered ring that are joined together. In DNA, cytosine binds with guanine, and thymine binds with adenine. The connection between cytosine and guanine is made of three hydrogen bonds, while the connection ...
The DNA itself consists of compounds known as nucleotides. In the smallest chromosome, in human beings, a molecule of DNA is said to contain about 50 million pairs of nucleotides. For each strand of DNA, the nucleotides are made up of a nitrogenous base/nucleobase (adenine (A), guanine (...
Nuclease(核酸酶) can pop the DNA in this way. It cuts the link between the nucleotides Well, the helicase(解旋酶) can cut thehydrogen bonds between the two strandand then it can separate the two strands of DNA from each other Most of the Cas enzymes arenucleasesor helicases ...
Polymerase is an enzyme found in cells that is used to create DNA and RNA molecules. There are several different types of DNA...
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 double helix is heated, then these hydrogen bonds break apart. The double-stranded DNA “melts” apart into single-stranded ...
2. The first genetic code The ribosomal RNAs are among the most conserved molecules in evolution and have the ability to form peptide bonds (Nitta et al., 1998), which means that they appeared very early on the primitive Earth and could stick amino acids together into peptides and polypeptid...
Covalent bonds (known as the phospho-diester linkage) between the sugar of one nucleotide and the phosphate of the next nucleotide link the nucleotides together in a chain, resulting in an alternating sugar-phosphate backbone. The nitrogenous bases of the two polynucleotide strands are linked ...
