What base does cytosine base-pair with?
Cytosine, a pyrimidine (sugar) base, pairs with Guanine, a purine (nitrogen) base.
How are base pairs held together in DNA molecules?
Base pairs in DNA molecules are held together by hydrogen bonds between the nitrogenous bases.
What is broken between base pairs during transcription?
During transcription, the hydrogen bonds between the complementary base pairs of DNA (adenine-thymine and guanine-cytosine) are broken to allow the RNA polymerase enzyme to create a single-stranded messenger RNA (mRNA) copy of the gene.
Are AT base pairs or GC base pairs more stable?
GC base pairs are more stable than AT base pairs because they have three hydrogen bonds holding them together, while AT base pairs have only two hydrogen bonds. This extra bond in GC pairs makes them stronger and more difficult to break apart.
What are base pairs in biotechnology?
In biotechnology, base pairs refer to the complementary pairing of nitrogenous bases in DNA molecules. Adenine pairs with thymine, and guanine pairs with cytosine. Understanding base pairs is crucial for techniques like PCR and DNA sequencing.
What do DNA polymerase do in DNA replication?
It breaks the hydrogen bonds between the base pairs
In DNA complementary base pairing occurs between what?
In DNA, complementary base pairing occurs between adenine (A) and thymine (T), as well as cytosine (C) and guanine (G). These base pairs form the double helix structure of DNA through hydrogen bonding.
How many base pairs are in human sperm DNA?
four base pairs
What base in RNA pairs with adenine-?
Uracil is the base in RNA that pairs with adenine.
How is DNA pared to DNA?
with hydrogen bonds between base pairs 2 between A and T and 3 between C and G
How long are the base pairs of Okazaki fragments?
Okazaki fragments are typically around 100-200 base pairs long in prokaryotes and around 1000-2000 base pairs long in eukaryotes.
What principle states that hydrogen bonds can form only between certain bases in DNA?
Chargaff's rule states that hydrogen bonds can form only between certain complementary base pairs in DNA. adenine pairs with thymine (or uracil in RNA) with two hydrogen bonds, while guanine pairs with cytosine with three hydrogen bonds.
