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 DNA base?
"Bases" when speaking of DNA refers to the nitrogen bases. There are four: adenine, guanine, cytosine, and thymine. They comprise the "rungs" of the DNA ladder and are hydrogen-bonded.
What are the ladders of DNA made of?
The 'steps' on the 'DNA Ladder' are made up of the four nitrogenous bases, Cytosine, Guanine, Thymine, and Adenine, while the pairing bases (Adenine & Thymine, Cytosine & Guanine) are bonded together with a hydrogen bond. The pairing bases (the 'rungs' of the ladder) are connected to the side posts of the ladder, which contain phosphate.
What group makes up the rungs or steps of DNA?
The rungs or steps of DNA are made up of nucleotide bases. There are four types of nucleotide bases: adenine (A), thymine (T), cytosine (C), and guanine (G). These bases pair up in a specific way (A with T and C with G) to form the rungs of the DNA ladder.
What four molecules make up the rungs of the ladder?
The four molecules that make up the rungs of the DNA ladder are adenine, thymine, guanine, and cytosine. Adenine pairs with thymine, and guanine pairs with cytosine through hydrogen bonding to form the base pairs of the double helix structure.
What are the four bases that make up the rings of the DNA ladder?
DNA is made up of deoxyribose, phosphate, and nitrogen bases (adenine, thymine, cytosine, and guanine). The rungs of the ladder are made of two bases joined together with either two or three weak hydrogen bonds.
What makes up the side of the DNA ladder?
Phospate groups and dioxyribose sugars. the "rungs" are made up of the four nitrogen bases--adenine, thymine, guanine and cytosine.
The structure of a DNA molecule resembles the shape of a twisted ladder In this model which part of the ladder is made of sugars and phosphates?
Adeninine - Thiamine and Guanine - Cytosine pairs.
If a man is standing on the middle step of a ladder he climbs down four steps and then up 9 to the top of the ladder how many steps are on the ladder?
11 rungs.
What are the internal blocks or rungs of the DNA ladder?
The four nitrogen bases, Guanine, Cytosine, Thymine, and Adenine. Thymine and Cytosine are pyrimidines and Guanine and Adenine are purines. Thymine bonds with Adenine and Cytosine bonds with Guanine.
What four nitrogen bases that make up DNA?
The four nitrogen bases that make up DNA are adenine (A), thymine (T), cytosine (C), and guanine (G). These bases pair up in specific combinations (A with T, and C with G) to form the rungs of the DNA double helix ladder.
What 4 bases make up DNA?
The four bases that make up DNA are adenine (A), thymine (T), cytosine (C), and guanine (G). These bases pair up to form the rungs of the DNA ladder in a specific way: A pairs with T and C pairs with G.
