Enzyme used to position nucleotides during DNA replication?
DNA polymerase is the enzyme responsible for positioning nucleotides during DNA replication. DNA polymerase can add nucleotides to the growing DNA strand in the 5' to 3' direction and proofread for errors in base pairing.
What is The action of helicase creates?
Helicase unwinds the double-stranded DNA by breaking the hydrogen bonds between complementary base pairs. This creates two single strands of DNA that can be used as templates for DNA replication or transcription.
What part of translation depends on the same base paring rule that is used in transcription and DNA replication?
The pairing of complementary nucleotides in RNA to match with the template DNA during transcription depends on the same base-pairing rule used in DNA replication. In both processes, adenine pairs with thymine (or uracil in RNA) and guanine pairs with cytosine.
What rule is used to join the free nucleotides to the exposed bases of the DNA?
The rule used to join free nucleotides to the exposed bases of DNA is base pairing. Adenine pairs with thymine, and guanine pairs with cytosine through hydrogen bonding. This complementary base pairing ensures the accurate replication of DNA during cell division.
What type of isotope was used to follow the construction of new DNA molecules during successive generations?
The isotope used was thymidine labeled with a radioactive isotope such as tritium (3H) or carbon-14 (14C). Thymidine is a nucleoside that gets incorporated into DNA during the replication process, allowing researchers to track the synthesis of new DNA molecules.
What nitrogen base isn't used during DNA replication?
uracil.
Which nitrogen base isn't used during replication?
Uracil (U) is not used during DNA replication, as it is found in RNA instead of DNA. DNA replication involves pairing adenine (A) with thymine (T) and cytosine (C) with guanine (G).
Why is an nitrogen is important nutrient?
Nitrogen is used for DNA replication, so you need it for cell replication and growth.
Does protein synthesis occur during replication?
No, protein synthesis does not occur during replication. Replication is the process of copying DNA, while protein synthesis occurs during transcription and translation, where DNA is used as a template to create proteins.
During DNA replication each strand of DNA is used as a template to produce a complementary strand of DNA. What base will attatch to location 2?
During DNA replication, the base that attaches to a specific location on the template strand depends on the base present at that location. If the base at location 2 on the template strand is adenine (A), then thymine (T) will attach to the complementary strand. Conversely, if the base at location 2 is cytosine (C), then guanine (G) will be added. The pairing follows the rules of complementary base pairing: A-T and C-G.

DNA polymerase is the enzyme responsible for positioning nucleotides during DNA replication. DNA polymerase can add nucleotides to the growing DNA strand in the 5' to 3' direction and proofread for errors in base pairing.
During DNA replication each strand of DNA is used as a template to produce a complementary strand of DNA. This process is shown below. Which base will attach to location 1?
Guanine
Meselson and Stahl used what type of isotopes to determine mechanism by which DNA replicated?
Meselson and Stahl used heavy isotopes of nitrogen (N^15 and N^14) to track the replication of DNA in E. coli bacteria. By switching from N^15 to N^14, they were able to demonstrate the semi-conservative mechanism of DNA replication.
What is The action of helicase creates?
Helicase unwinds the double-stranded DNA by breaking the hydrogen bonds between complementary base pairs. This creates two single strands of DNA that can be used as templates for DNA replication or transcription.
During replication what enzyme is used to split the DNA molecule in half?
helicase
What part of translation depends on the same base paring rule that is used in transcription and DNA replication?
The pairing of complementary nucleotides in RNA to match with the template DNA during transcription depends on the same base-pairing rule used in DNA replication. In both processes, adenine pairs with thymine (or uracil in RNA) and guanine pairs with cytosine.
