Which of the following is true for DNA replication?
Explanation: In eukaryotes one strand of DNA is synthesized continuously but the other one is made of Okazaki fragments. 4. Which of the following is true about DNA polymerase? Explanation: DNA pol can synthesize only a new DNA strand not m-RNA.
Which description of DNA replication is correct?
Which description of DNA replication is correct? – Ligase separates the two strands of the DNA double helix. Then, DNA polymerase synthesizes the leading strand and primase synthesizes the lagging strand. – The two strands separate, and each one receives a complementary strand of RNA.
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.
What are the 3 rules of DNA replication?
The rules are: 1. Replication is a Semi-conservative Process 2. Replication has Direction 3. Replication Starts off a Unique Point on Bacterial and Viral Chromosomes 4.
Which statement about DNA replication is false?
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 about the primers in DNA synthesis?
Which of the following statements about DNA synthesis is true? Primers are short sequences that allow the initiation of DNA synthesis. When a primer is added to a single strand of DNA, DNA polymerase can start adding nucleotides to synthesize a complementary strand. … They are formed on the lagging strand of DNA.
What statement about the major and minor grooves is true?
What statement about the major and minor grooves is TRUE? The major and minor grooves are important for DNA binding proteins to attach to the DNA.
How does the structure of DNA result in accurate replication?
DNA replication occurs through the help of several enzymes. These enzymes “unzip” DNA molecules by breaking the hydrogen bonds that hold the two strands together. Each strand then serves as a template for a new complementary strand to be created. Complementary bases attach to one another (A-T and C-G).
Where does DNA replication happen?
DNA replication occurs in the cytoplasm of prokaryotes and in the nucleus of eukaryotes. Regardless of where DNA replication occurs, the basic process is the same. The structure of DNA lends itself easily to DNA replication. Each side of the double helix runs in opposite (anti-parallel) directions.
Which statement is true of DNA structure?
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 statements best describes DNA polymerase?
Which of the following statements best describes DNA polymerase? It is an enzyme that catalyzes the addition of nucleotides to the 3′ end of a growing DNA strand. Which of the following is the highest (or most complex) level of structure for genetic material?
How do DNA Polymerase I and DNA Polymerase III differ?
How do DNA polymerase I and DNA Polymerase III differ? DNA Polymerase III synthesizes the majority of the DNA, while DNA Polymerase I synthesizes DNA in the regions where the RNA primers were laid down on the lagging strand.
Which statement 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 of the following statements best describes the overall process of DNA replication?
Which of the following statements best describes the overall process of DNA replication? A double stranded DNA molecule is replicated to form two double-stranded DNA molecules, each containing one parent strand and one new strand. Which enzyme is responsible for “unzipping” the initial parent DNA molecule?
Which is true of hydrogen bonds in the DNA molecule quizlet?
Which is true of hydrogen bonds in the DNA molecule? They are weak so that the strand can be easily broken for replication. … The two strands of DNA need to be separated so new bases can pair with each template strand.
Which of these is always true with regard to a DNA double helix?
What is always true with regard to a DNA double helix? adenine=thymine guanine=cytosine. One strands runs in the 5″ to 3″ direction and the other strand runs in the 3″ to 5″ direction.
What statement is A valid scientific hypothesis?
The two primary features of a scientific hypothesis are falsifiability and testability, which are reflected in an “If…then” statement summarizing the idea and in the ability to be supported or refuted through observation and experimentation.
Why must DNA replication occur exactly?
DNA replication needs to occur because existing cells divide to produce new cells. Each cell needs a full instruction manual to operate properly. So the DNA needs to be copied before cell division so that each new cell receives a full set of instructions!
Which of the following statements about the orientation of DNA strands 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 is not true or DNA double helix structure?
The correct option: The structure which is not true for a DNA molecule is B. Single-stranded.
What do you understand by the double helical structure of DNA who proposed this structure?
In 1953, Francis Crick and James Watson first described the molecular structure of DNA, which they called a “double helix,” in the journal Nature. For this breakthrough discovery, Watson, Crick, and their colleague Maurice Wilkins won a Nobel Prize in Physiology, or Medicine, in 1962.
