What two bases are in purines?
Adenine and guanine are the two purines bases present in DNA.Two purines in DNA are adenine and guanine.
What type of mutation results when bases are added to the gene?
This is called an insertion mutation.Some repeats, such as the repeats in the Huntington's gene, can be repeated too many times and then you have the deleterious mutation in this gene.
What is the attraction between nitrogenous bases?
The attraction between nitrogenous bases is due to hydrogen bonding. This bonding occurs between specific pairs of bases in DNA (adenine-thymine, guanine-cytosine) and RNA (adenine-uracil, guanine-cytosine), contributing to the stability of the double helix structure.
How many guanine bases a length of DNA will have if it has 26 cytosine bases?
In a double-stranded DNA molecule, the bases pair specifically: adenine pairs with thymine, and guanine pairs with cytosine. This means that for every cytosine base, there is a corresponding guanine base. Therefore, if there are 26 cytosine bases in the DNA, there will also be 26 guanine bases.
What bases are found in DNA?
Adenine, Thymine, Guanine, and Cytosine
What two extra guanine bases are added to the DNA during DNA replication what mutation is this?
This is a frameshift mutation and will render the rest of the DNA sequence useless.
What if during DNA replication two extra guanine bases are added to the DNA. What type of mutation is this?
If two extra guanine bases are added during DNA replication, it results in a mutation known as a frameshift mutation. This occurs because the addition alters the reading frame of the genetic code, potentially leading to significant changes in the resulting protein sequence. Frameshift mutations can disrupt protein function and may lead to various genetic disorders or diseases.
What type of mutation result when bases are added to gene?
Frame shift mutation occurs when a new codon in inserted. Point mutations occurs when one base, sometimes two, are inserted.
Which type of mutation results when bases are added to a gene?
An insertion mutation occurs when extra bases are added into a gene. This can disrupt the reading frame, leading to a shift in the way the genetic code is interpreted during protein synthesis.
Which type of mutation results when bases added to a gene?
Frameshift ~
What types of mutation results when bases are added to a gene?

Does a mutation in a gene affect the order of DNA bases?
A mutation in a gene can happen by addition, deletion or substitution of base pairs. This means that the order of the bases will change- a new base may be added, a base may be lost, or one base may be substituted for another. The result of these mutations is that it causes the DNA to code for a different protein. If a mutation occurs in a sex cell, the mutation can be passed on to an offspring and affect the offspring's phenotype.
