What is the function of primers?
RNA primers are used to initiate the DNA replication at the template strand. DNA molecules require a free 3' OH, to which it could add the nucleotides. This free 3' OH is provided by the RNA primer. So prior to the synthesis of DNA a short fragment of RNA is synthesized that is later excised and filled with DNA molecules.
What is 5 minus 3 and 3 5?
5 - 3 and 3/5 = 1 and 2/5
What is 1 third of 5 add 5?
1/3 of 5 add 5 = 1/3*5 + 5 = 5/3 + 5 = 12/3 + 5 = 62/3 or 20/3
How does 3 3 5 5 equal 24?
5 * 5 - (3 / 3) = 24
Subtract the square of 5 from the square of -3?
√-3 - √5 = i√3 - √5 = -√5 + i√3
What is the DNA strand that is synthesized continuously during DNA replication?
The leading strand is the DNA strand that is synthesized continuously during DNA replication. This is because the polymerase enzyme can add nucleotides in the 5' to 3' direction without interruption as the replication fork opens.
In which direction does RNA polymerase read a DNA strand?
The correct answer is: RNA is synthesized by RNA polymerase that reads one strand of DNA. RNA polymerase reads DNA 3' to 5'. When RNA is made, it is made 5' to 3'. Most polymerases have the 3' to 5' "reading" activity. The created RNA strand is identical to the coding strand of DNA, which is also in the orientation of 5' to 3'.

When DNA replicates what are the new DNA made of?
During DNA replication, the new DNA strands are made of nucleotides. These nucleotides consist of a phosphate group, a sugar molecule (deoxyribose), and one of four nitrogenous bases (adenine, thymine, cytosine, or guanine). The nucleotides form complementary base pairs with the existing DNA strands to create two identical copies.
What is replicating the lagging strand of DNA that is adding bases in the 3-5 direction utilizes what?
The lagging strand of DNA is replicated using a process called Okazaki fragments. These are short DNA fragments synthesized in the 5' to 3' direction by DNA polymerase, and are subsequently joined together by DNA ligase to form a continuous strand.
An okazaki fragment has which of the following arrangements?
An Okazaki fragment is a short, newly synthesized DNA fragment that is formed on the lagging strand during DNA replication. It is composed of a short RNA primer at the 5' end and DNA nucleotides that extend toward the replication fork.
Which of the following statements best explains why the leading and lagging strands are synthesized using two different mechanisms?
The leading and lagging strands are synthesized using different mechanisms because DNA replication occurs in a 5' to 3' direction, but the two strands of DNA are antiparallel. This means that one strand is oriented in the 3' to 5' direction (leading) and the other in the 5' to 3' direction (lagging), requiring discontinuous replication on the lagging strand.
IF DNA is labeled radioactive and allowed to replicate how much radioactivity in newly synthesized DNA?
The amount of radioactivity in the newly synthesized DNA will be equal to that of the original labeled DNA. Since the labeled DNA is used as a template for replication, the radioactivity is retained in the newly synthesized strands.
What okazaki fragments are?
In DNA replication, the two DNA strands acting as templates need to be synthesized simultaneously. DNA polymerase is an enzyme which can synthesize the DNA only in 5' to 3' direction.the two template strands are anti-parallel to each other and their complementary strands are synthesized in different direction. In one of the strand DNA is synthesized continuously by adding nucleotides at 3'-OH end. this is referred as 'leading strand' synthesis. the other strand to be synthesized is replicated in short fragments referred 'Okazaki fragments' named after their discoverer Reiji Okazaki.
What are leading strands?
Leading strands are one of the two newly synthesized DNA strands during DNA replication. They are synthesized in a continuous manner in the 5' to 3' direction, following the replication fork. The leading strand is synthesized in the same direction as the replication fork is moving, allowing for continuous synthesis.
Which statement best describes strand characteristics as it relates to DNA replication?
Strand characteristics in DNA replication refer to the direction in which new DNA strands are synthesized. DNA replication is semi-conservative, meaning each new DNA molecule consists of one original (parental) strand and one newly synthesized (daughter) strand. The strands are antiparallel, with one strand running 5' to 3' and the other running 3' to 5'.
The process by which RNA is synthesized from the DNA?
