rails
The rungs on a ladder are held between the rails.
The rungs are made of 4 different types of bases. The bases letters are A,T,G, and C. Only A and T can go together, and only G and C can go together.
The ladder had 25 rungs in total. This can be calculated by adding the 7 rungs walked down to the 15 rungs climbed up, then adding the final 3 rungs. So, 7 + 15 + 3 = 25 rungs on the ladder.
Each rung of the DNA double helix is made up of a pair of nitrogenous bases (adenine-thymine or guanine-cytosine). The sides of the ladder are made up of alternating sugar (deoxyribose) and phosphate molecules. Hydrogen bonds hold the nitrogenous bases of the rungs together, creating the structure of the DNA double helix.
Wood glue holds boards together.
The cell membrane holds a cell together.
The steps of a ladder are called rungs.
well all say the gravity holds everything together but i don't know what holds everything together
chemical bond holds together the atoms in a substance
The cell membrane, which is like a plastic baggy, holds the nucleus together.
The nitrogenous bases Adenine, Thymine, Guanine, and Cytosine Adenine and Thymine are always together and Cytosine and Guanine are always together.
The rails of DNA are made up of pairs of sugars and phosphates. The middle of the strand of DNA or the rungs are made of nucleotides and bases of codons, such as ATCG base pairs. The bond that holds the DNA together is a hydrogen bond.
