Uracil. Uracil is not present in DNA, but it is present in RNA. DNA's "equivalent" base is thymine, meaning when DNA is transcribed into RNA, the places where thymine would go instead has uracil.

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.


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.


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


During replication what enzyme is used to split the DNA molecule in half?

helicase


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.


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.


Were both Nitrogen Mustards and Sulfur Mustards used during World War 1?

No the nitrogen mustards were stockpiled during world war one but, they were never used.
