DNA is an example of a macromolecule, i.e. a large molecule with a special shape, which is built up from many smaller parts called sub-units .If you could magnify part of a nucleus, you would see the DNA molecule looking like a twisted rope ladder - a double helix. The two strands forming the sides of the ladder give it a strong yet flexible structure, which does not vary along its length. Stretched between these are the "rungs" of the ladder, the parts of the DNA molecule which vary, and so the differences carry genetic information. These parts are made up of sections called bases, which fit together in pairs. Single section of DNA The 4 bases (so called because on their own they react with acids) are also usually known by their initials, as shown alongside: A (adenine), paired with T (thymine) and C (cytosine) paired with G (guanine).

What is the name for the segments of a DNA molecule that are each made up of many rungs?

The segments of a DNA molecule that are each made up of many rungs are called nucleotide sequences. These sequences consist of specific arrangements of four different nucleotides: adenine (A), thymine (T), cytosine (C), and guanine (G) that form the genetic code in DNA.


How many rungs are in a DNA molecule?

A DNA molecule consists of two strands that are connected by hydrogen bonds between complementary bases. Each strand has a backbone made up of alternating sugar and phosphate groups, with bases extending inward. The number of rungs in a DNA molecule depends on the length of the molecule, with each base pair forming one "rung."


What does a molecule contain?

Hemoglobin is a protein with repeating segments called heme, each of which contains an iron atom, which is the active site where oxygen can be carried.


DNA is in the form of a ladder with rungs of equal length although the rungs may vary in composition What accounts for the equality of length?

DNA's rungs are made from a purine that is longer and always Guanine (G) or Adenine (A) and a pyrmidine which is small and always Cytosine (C) or Thymine (T). So each DNA rung is always equal with a base pair of ( A ) and ( T ) or ( G ) and ( C ).


Are ladder rungs horizontal or parallel?

Ladder rungs are typically horizontal, meaning they are perpendicular to the vertical side rails of the ladder. Each rung is parallel to the ground when the ladder is in use.


What are perpendicular line segments?

Perpendicular line segments are line segments that cross with each other and form angles of 90 degrees.


The DNA in the nucleus of a cell contains thousands of segments know as the what?

The DNA in the nucleus of a cell contains thousands of segments known as genes. Each gene carries the instructions to produce a specific protein or RNA molecule, playing a vital role in determining an organism's traits and functions.


Millipedes and centipedes each have a head region followed by numerous segments of?

15 body segments.


What are the rungs steps of a DNA molecule made of?

The 'steps' or 'rungs' of the DNA 'ladder' are complimentary pairs of bases bonded by hydrogen bonds. The bases are Adenine, Thymine, Cytosine and Guanine. Adenine always bonds to Thymine and Cytosine always bonds to Guanine.


What part represents the rungs of the DNA ladder?

Two nitrogen bases are linked together to form the "rungs of the ladder". The four possible nitrogen bases are Adenine, Thymine, Guanine and Cytosine, assigned A, T, G and C. A will always be paired with T, and G with C. The bases (A, T, G and C) are attached to the five-carbon sugar deoxyribose and a phosphate group, which make up the framework of the DNA molecule.


What are parellel line segments?
