Which of the following statements about dna is true

DNA has a double-helical structure with two nucleotide chains that run anti-parallel, the outer edges are formed by alternating deoxyribose sugar molecules and phosphate groups, which make up the sugar-phosphate backbone. Hence statement 3 is correct.

Which of the following about DNA structure is true?

Which of the following statements about DNA structure is true? The nucleic acid strands in a DNA molecule are oriented antiparallel to each other, meaning they run in opposite directions. This statement is true; the 5′, 3′ orientation of each chain runs in opposite directions.

Which of the following statement is true for DNA replication?

So, the correct answer is 'DNA replication begins at the promoter'.

Which of the following statement is not true about DNA?

Hence, the correct answer is 'It contains the sugar ribose'.

Which of the following is incorrect about DNA?

The fourth base is Thymine in DNA & Uracil in RNA.

Which of the following best define DNA?

The molecule inside cells that contains the genetic information responsible for the development and function of an organism. DNA molecules allow this information to be passed from one generation to the next.

What is the true structure of DNA quizlet?

DNA is made up of two strands of nucleotides. The nucleotides are made up of a sugar (deoxyribose in DNA), a phosphate, and a nitrogen base. The sugars and phosphates make up the "handrails" (or "backbone"), and are held together by covalent bonds.

Which statement is true of DNA cloning quizlet?

Which statement is true of DNA cloning? It is used to isolate specific sequences of DNA, and it requires the enzyme DNA ligase.

Which of the following is true of DNA during interphase quizlet?

Which of the following is true of DNA during interphase? It exists as chromatin and is unavailable for gene expression. Chromatin is the term for the loosely coiled DNA observed in cells during interphase. Even during interphase, however, parts of the chromosome may still be rather tightly coiled and packed.

Which of the following is not true about DNA replication *?

So, the correct option is 'DNA can only replicate at one point on a chromosome at one time'.

Which one of the following statements about DNA replication is incorrect?

Answer and Explanation: The statement pertaining to DNA replication that is false is D: Okazaki fragments are synthesized as part of the leading strand.

Which of the following statement is false about DNA replication?

The correct answer choice is b. DNA replication cannot be "hijacked" by viruses.

Which of the following statements is true of DNA damage?

All DNA damage is caused by physical , chemical or biological agent.

Which of the following statements does not describe the structure of DNA?

Its nucleotide bases contain adenine, uracil, cytosine, and guanine. Therefore, the answer is D. It is because DNA does not contain adenine and uracil pairs.

Which statement most accurately describes the proper relationship of DNA?

DNA strands are held together with ionic bonds. Which statement most accurately describes the proper relationship of DNA? Genes are segments of DNA and chromosomes are made up of DNA.

What are mistakes in DNA known as?

Mutations. When there is a mistake in the copying of the genetic message that is permanent, a mutation has occurred.

Which one of the following is not character by the DNA?

Uracil is unique in RNA. It is not found in DNA. Instead of uracil in DNA, thymine is present.

Which of the following step is incorrect in DNA fingerprinting?

Since DNA fingerprinting does not study RNA, Northern blotting is not used. Correct answer is D.

What are 5 characteristics of DNA?

The DNA molecule is a double helix structure. The two strands of a DNA molecule are anti-parallel( one is 3' to 5' direction and another one is 5' to 3' direction) and twisted. It is made up of four nucleotides - adenine(A), guanine(G), cytosine(C), and thymine(T).

What is DNA very short answer?

DNA, or deoxyribonucleic acid, is the hereditary material in humans and almost all other organisms. Nearly every cell in a person's body has the same DNA.
