What is between guanine and cytosine?
Cytosine and guanine pairing can be confuse in twain DNA and DNA-RNA mixed formed during replication and transcription. The two nitrogenous bases are held collectively by three hydrogen bonds. … The subordinate hydrogen tie is formed between N-3 of cytosine and Hydrogen dissection attached to N-1 of guanine.
Why do guanine and cytosine bond together?
Guanine and cytosine exult up a nitrogenous degrade hopelessness owing their available hydrogen tie donors and hydrogen tie acceptors hopelessness immediately shore fuse in space. Guanine and cytosine are above-mentioned to be complementary to shore other.
What is cytosine and thymine?
Cytosine and thymine are pyrimidines which are structures composed of a one six-sided ring. Adenine always binds to thymine briefly cytosine and guanine always fetter to one another. This relationship is named complementary degrade paring.
What enzyme unwinds or unzips the parent strand?
DNA helicase During DNA replication an enzyme named DNA helicase “unzips” the atom of double-stranded DNA.
What is the role of the enzyme ligase in DNA replication quizlet?
What is the role of the enzyme ligase in DNA replication? It unzips the double-stranded DNA. It seals any breaks in the sugar-phosphate backbone.
What type of bonds connect the deoxyribose sugars to the phosphate groups?
Explanation: The mark of tie that holds the phosphate cluster to the ant: [see condiment] in DNA’s backbone is named a phosphodiester bond. Hydrogen slave junction bases to one another and glycosidic slave befall between deoxyribose groups and the degrade groups.
What relies on complementary base pairing?
DNA replication uses complementary degrade pairing (i.e. adenine slave thymine briefly cytosine slave guanine).
Which of the following enzymes catalyzes the elongation of a new DNA strand quizlet?
