The back-bone of DNA is called 'the sugar-phosphate backbone' because: the ribose [or the 2' [two-prime] deoxy-ribose] sugars that 'make up' the backbone binding portion of the (one of four) nucleotide bases is interlaced with the phosphate moieties.
Compare to adding N to the C chain to gain strength.

The phosphate portion of a phospholipid is?
polar and can form hdrogen bonds with water molecules
Is MgPO4 a ionic or covalent bond?
Magnesium Phosphate is an ionic molecule, it has a positively charged metal (Magnesium) and a negatively charged nonmetal portion (phosphate group) with a net zero charge since the charges cancel each other out.
How do you make Trisodium phosphate?
reaction equal portion of phosphoric acid and soda ash then add sodium hydrohide to ph 12 befor crysalization.
How many nucleotides make an amino acid?
3 are needed. As there are 20 amino acids used in proteins, each amino acid would have to be encoded by a minimum of three nucleotides. For example, a code of two consecutive nucleotides could specify a maximum of 16 (42) different amino acids, excluding stop and start signals. A code of three consecutive nucleotides has 64(43) different members and thus can easily accommodate the 20 amino acids plus a signal to stop protein synthesis.
What is the coding region in DNA transcription?
The coding region of a gene is that portion of a gene's DNA or RNA, composed of exons, that codes for protein. The coding region of an organism is the sum total of the organism's genome.
Where is the hydrophilic portion of membrane?
The head is hydrophilic and the tail is hydrophobic.
What is the bone matrix?
The matrix of the bone is portion of specialized connective tissue composed of intercellular, is contain an organic and inorganic materials 1- The organic material: collagen ( type I) 2- The inorganic material: calcium phosphate
What portion of the IP address does the prefix represent?
It represents the network portion
The phosphate portion of a phospholipid is?
polar and can form hdrogen bonds with water molecules
What does the blue portion of the globe represents?
the oceans
What does the dark portion of the globe represents?
Where it is night.
What kind of molecules are the nucleotides?
All nucleotides have: 1) a phosphate group (same for all nucleotides) 2) a 5-carbon sugar (same for a particular type of nucleic acid - deoxyribose for DNA, ribose for RNA) 3) nucleoside (purine or pyrimidine base - varies for each nucleotide - there are 5 total - 4 for DNA (adenine, cytosine, guanine, thymine) - 4 for RNA (adenine, cytosine, guanine, uracil)
Noncoding portion of DNA is composed of?
A noncoding portion of DNA is called an intron, and is composed of codons that will eventually be removed after transcription when the final mature strand of mRNA is produced.
The portion of the skin that is composed of nonliving cells is the?
stratum corneum
Which part of a dna nucleotide contains a negative charge?
The DNA nucleotide consists of three parts: a phosphate group, a 5-carbon sugar, and a nitrogenous base. The portion of the nucleotide that contains a negative charge is the phosphate group.
What are the Three enzymes used in DNA replica and their functions?
Helicase: Unwounds a portion of the DNA Double HelixRNA Primase: Attaches RNA primers to the replicating strands.DNA Polymerase delta (ä): Binds to the 5' - 3' strand in order to bring nucleotides and create the daughter leading strand.DNA Polymerase epsilon (å): Binds to the 3' - 5' strand in order to create discontinuous segments starting from different RNA primers.Exonuclease (DNA Polymerase I): Finds and removes the RNA PrimersDNA Ligase: Adds phosphate in the remaining gaps of the phosphate - sugar backboneNucleases: Remove wrong nucleotides from the daughter strand.
Is the following true or false the visible portion of the electromagnetic spectrum represents a large portion of the spectrum?
False
