What is the structure of the staircase of a DNA molecule?

 · Question 4 2.5 out of 2.5 points If a DNA molecule was a spiral staircase, what would the steps of the staircase be? Answer Selected Answer: base …

How can one strand of DNA become two?

 · a) The spiral staircase's hand rail will be equivalent to the sugar phosphate base of DNA that holds the nitrogenous base. b) The steps of spiral case will be equivalent to the pair of nitrogenous base . Nitrogenous base pair include - Pair of adenine (A) and thymine (T) - Pair of guanine (G) and cytosine (C) Thus, option A is correct

What is the structure of DNA?

 · If a DNA molecule is compared to a spiral staircase what part make up the steps? guanine, cytosine, thymine, adenine.

What makes up the steps of the DNA spiral staircase?

The inside of the molecule, the "steps" of the staircase, are made of the nucleotide bases Cytosine, Guanine, Adenine, and Thymine.

Why is DNA molecule is compared to a spiral staircase?

If DNA Molecules is compared to a spiral staircase, then the pair of nitrogen bases and bonds between them would be considered as their steps. The pair of nitrogen bases, which includes Adenine, Guanine, Cytosine, and Thymine. Besides, there are two molecules that makeup DNA, which is deoxyribose and phosphate group.

Which parts of the DNA molecule are like the steps of the spiral staircase which parts are the hand rails most similar to?

9. The DNA double helix is similar to a spiral staircase: the sugar-phosphate backbone is like the twisting handrails of the staircase, and the nitrogen-containing bases are like the steps that connect the railings to each other.

What is the staircase of DNA called?

double helixThe structure of DNA is called a double helix, which looks like a twisted staircase. The sugar and phosphate make up the backbone, while the nitrogen bases are found in the center and hold the two strands together.

What molecule forms the steps of the DNA ladder?

They showed that alternating deoxyribose and phosphate molecules form the twisted uprights of the DNA ladder. The rungs of the ladder are formed by complementary pairs of nitrogen bases — A always paired with T and G always paired with C.

What are the steps of DNA replication?

Replication occurs in three major steps: the opening of the double helix and separation of the DNA strands, the priming of the template strand, and the assembly of the new DNA segment.

Which part of the DNA helix is the rungs or steps?

The phosphate and deoxyribose molecules form the sides of the DNA ladder while nitrogenous bases form the rungs.

What are the names of the 4 bases that form the sequence of DNA quizlet?

The bases include: A, (adenine), g (guanine), t (thymine), c (cytosine). The phosphate and sugar molecule bonds form the backbone or hand rail of the DNA (staircase), but the genetic key is in the steps (of the stairs): the bases. The bond in a specific way: A-T and C-G.

What are the names of the 4 bases that form the sequence of DNA?

The four bases in DNA are adenine (A), cytosine (C), guanine (G), and thymine (T). These bases form specific pairs (A with T, and G with C).

Why is DNA a spiral?

The twisting aspect of DNA is a result of interactions between the molecules that make up DNA and water. The nitrogenous bases that comprise the steps of the twisted staircase are held together by hydrogen bonds. Adenine is bonded with thymine (A-T) and guanine pairs with cytosine (G-C).

How is a DNA molecule like a ladder?

So, DNA is like a twisted ladder, where the sugar and phosphate are the rails, and the base pairs are the rungs. The rails run in opposite orientation to each other. The nucleotide rungs are complementary to each other. Wherever there is an A on one strand, there is a T in the same position on the other strand.

What is a twisted DNA ladder called?

DNA is also called a three-dimensional double helix. It looks much like a twisted ladder, and the backbone of the ladder is made of sugar phosphates.

What are the steps of the DNA staircase?

In this comparison, the "steps" of the DNA staircase would consists of the pairs of nitrogen bases, which are Adenine, Guanine, Cytosine, and Thymine.

What are the steps of spiral case equivalent to?

b) The steps of spiral case will be equivalent to the pair of nitrogenous base

What can be used to isolate DNA molecules from living organisms?

d. X-rays can be used to isolate DNA molecules from living organisms.

Which molecules scatter x-rays?

a. Only DNA molecules scatter x-rays; therefore, this helped to prove that DNA was the genetic material in cells.

How are X-rays scattered?

X-rays are scattered by atoms in a specific pattern, from which molecular size, shape, and spacing of repeating elements can be calcula ted. c. X-rays are reflected by some atoms and absorbed by others; thereby giving clues to molecule structure. d. X-rays can be used to isolate DNA molecules from living organisms. e.
