Is a DNA molecule a polymer?
DNA consists of two long polymers (called strands) that run in opposite directions and form the regular geometry of the double helix. The monomers of DNA are called nucleotides. Nucleotides have three components: a base, a sugar (deoxyribose) and a phosphate residue.
What is the polymer structure of DNA?
DNA. DNA is a polymer made from four different monomers , called nucleotides . These join together in different combinations to make long strands. In a DNA molecule , two strands wrap around each other to form a double helix structure.
Why is the polymer DNA considered antiparallel?
The sugar and phosphate make up the backbone, while the nitrogen bases are found in the center and hold the two strands together. Due to the base pairing, the DNA strands are complementary to each other, run in opposite directions, and are called antiparallel strands.
What does it mean when DNA molecules are antiparallel?
Antiparallel: A term applied to two molecules that are side by side but run in opposite directions. The two strands of DNA are antiparallel. The head of one strand is always laid against the tail of the other strand of DNA.
Why DNA is A polymer?
DNA is a polymer due to the fact it contains multiple repeating units (monomers). These monomers are known as nucleotides. Multiple nucleotides join together by phosphodiester bonds to form the polymer that is DNA.
Which molecule is the polymer?
Polymers are large molecules made up of long chains or networks of smaller molecules called monomers. Natural polymers include silk, hair, proteins and DNA, while synthetic (man-made) polymers include polyethylene, polypropylene and polyester.
What are the polymers of DNA called?
What means antiparallel?
Definition of antiparallel : parallel but oppositely directed or oriented antiparallel electron spins two antiparallel chains of nucleotides comprise DNA.
Why is DNA antiparallel quizlet?
-linked by hydrogen bonding between complementary base pairs. -The two strands are parallel but run in opposite directions so they are said to be antiparallel. -The strands are held together by hydrogen bonds between the nitrogenous bases.
What is the symbol of antiparallel?
I belive that when we talk about vectors you can use a ↑ ↑ b a parrowparrow b a↑↑b for parallel vectors and a ↑ ↓ b a parrow\downarrow b a↑↓b for antiparallel.
What does antiparallel mean quizlet?
A term applied to two molecules that are side by side but run in opposite directions. The two strands of DNA are antiparallel. The head of one strand is always laid against the tail of the other strand of DNA.
