Which statement about dna replication is true
What is true about DNA replication?
DNA replication is the process by which a double-stranded DNA molecule is copied to produce two identical DNA molecules. Replication is an essential process because, whenever a cell divides, the two new daughter cells must contain the same genetic information, or DNA, as the parent cell.
What statement about DNA replication is true quizlet?
What statement about DNA replication is true? The leading strand is syntesized continuously while the lagging strand is synthesized in a series of small fragments that are later connected. DNA polymerase synthesizes short fragments of DNA on the lagging strand during DNA replication.
Which statement is false about DNA replication?
The statement pertaining to DNA replication that is false is D: Okazaki fragments are synthesized as part of the leading strand. DNA replication…
Which of the following statements is true concerning DNA replication and transcription?
Which of the following statements is true concerning DNA replication and transcription? Possible Answers: Both strands act as templates in replication and transcription. Both use DNA as the template.
Why is DNA replication accurate quizlet?
DNA replication accuracy is improved thanks to complementary base pairing rules. Bacterial cells use DNA replication to: copy their genetic material prior to binary fission. Of the following enzymes, which are correctly matched with their function?
Which of the following is a true about DNA polymerase?
4. Which of the following is true about DNA polymerase? Explanation: DNA pol can synthesize only a new DNA strand not m-RNA. It can do this in the 5′ to 3′ direction.
Which of the following statements is not true about the structure of DNA?
The correct option: The structure which is not true for a DNA molecule is B. Single-stranded. The structure of a DNA molecule is formed with the…
Which of the following statement is true about transcription?
The statement regarding transcription and translation that is true is A: During transcription, an mRNA molecule is created from the DNA molecule.
Which of the following is are not true about DNA?
The two strands in DNA molecules are complementary to each other. … DNA strand contains pentose – 2 – deoxyribose sugar. Thus, option (C ) is incorrect.
Which statement is true about DNA replication in prokaryotes but not about replication in eukaryotes?
The only true statement is that prokaryotic DNA replication is faster than eukaryotic DNA replication.
Which of the following statements is true with respect to the DNA double helix?
4. Which of the following statements is true with respect to the DNA double helix? Explanation: The two strands having complementary base pairing have the same helical geometry but have opposite polarity. This is because the strands are held together are antiparallel in nature.
Which of the following is true with regard to a DNA molecule quizlet?
Which of the following is TRUE with regard to a DNA molecule? The amount of adenine is equal to the amount of thymine, and the amount of guanine is equal to the amount of cytosine. If one strand of a DNA double helix has the sequence AGTACTG, what will be the sequence of the other strand? How does RNA differ from DNA?
Which statement is true for DNA replication in prokaryotes when compared to eukaryotes?
In eukaryotic cells, the replication can be initiated at multiple origin sites and the process occurs within the nuclear structure. In contrast, the prokaryotic cells can initiate replication mechanism at one origin site only and the process occurs within the cytoplasm. Therefore, the correct option is C.
What is not true for DNA in prokaryotic?
Genetic material of prokaryotic cells is carried on a single circular of DNA which is attached to the cell membrane and in direct contact with the cytoplasm. There is no envelope membrane, so there is no true nucleus, and prokaryotes lack histone protein but simply a prokaryotic DNA known as a nucleoid.
Which statement does not describe DNA in a eukaryotic cell?
What statement does not describe DNA in a eukaryotic cell? DNA is not found in a nucleus.
What is true about DNA replication in eukaryotes?
In eukaryotes, the vast majority of DNA synthesis occurs during S phase of the cell cycle, and the entire genome must be unwound and duplicated to form two daughter copies. … This mechanism is conserved from prokaryotes to eukaryotes and is known as semiconservative DNA replication.
What is true about the lagging strand during DNA replication?
On the lagging strand, the DNA plymerase moves the opposite direction as helicase, thus it can only copy a small length of DNA at one time. Because of the different directions the two enzymes moves on the lagging strand, the DNA chain is only synthetised in small fragments. Hence it is called the lagging strand.
What is true about DNA and RNA?
DNA and RNA share many characteristics. They are both composed of nucleotide monomers and are read in the 5′-to-3′ direction. They also share the same complementary base pairs, except RNA uses uracil in place of thymine; both contain adenine.
What statement applies to both eukaryotic and prokaryotic replication?
Both eukaryotic and prokaryotic DNA polymerases build off RNA primers made by primase. Eukaryotic DNA replication requires multiple replication forks, while prokaryotic replication uses a single origin to rapidly replicate the entire genome. DNA replication always occurs in the nucleus.
Is DNA replication described as conservative or semi Conservative What does that mean?
DNA replication is semi-conservative because each helix that is created contains one strand from the helix from which it was copied. … It is semi- conservative because half of each parent helix is conserved in each daughter helix.
