Which base is only found in RNA nucleotides?
Uracil is only found in RNA nucleotides. In DNA uracil is replaced by thymine.
Is strand of nucleotides in the RNA or DNA?
Both, but RNA sometimes only has 1 side of unpaired nucleotides.
What part of the nucleotides changes?
The sugar and phosphate group of nucleotides never change. There are four possible nitrogenous bases and thus it is the only part of nucleotides that can change.
Consisting of only about 80 nucleotides?
tRNA
What occurs when extra bases are put into a DNA molecule during replication?
However, in eukaryotes only, there are extra sequences in the DNA and mRNA that don't code for proteins called introns. This mRNA is then further processed:Introns get cut outThe coding sequences get spliced togetherA special nucleotide "cap" gets added to one endA long tail consisting of 100 to 200 adenine nucleotides is added to the other end
Only one or two nucleotides are changed in a certain mutation this is an example of?
Only one or two nucleotides are changed in a certain mutation. This is an example of a(n)
Mutations that change one or just a few of nucleotides in a gene on a chromosome are called what?
the correct answer is C. a substitution i know this cause i have this book to this question and point mutation is not one of the answer and i found the answer in the book -No its substituton you jack wagon your books wrong
Who does somatic mutation affect?
A somatic mutation is one that occurs in any body cell with the exception of the gametes (sperm and eggs). A somatic mutation cannot be passed on to offspring, so it affects only the person with the mutation.
A mutation that involves a single nucleotide is called a(an)?
Point Mutation- a type of gene mutation in which only a single nucleotide in a gene has been changed.
Why does a mutation in a sex cell affect an organism?
It only affects the offspring of the organism.
Is the source of brand new genes in a population called mutation?
Yes, brand new genes can only come from mutation.
What can predict whether a mutation in a human skin cell can be passed to its offspring?
A mutation in a human skin cannot be passed on to an offspring, since it is only a somatic mutation which is acquired. The mutation that can be passed on to an offspring is called a germline mutation, which happens in the egg and sperm.
How many amino acids are affected from point mutation?
A point mutation can affect the protein in a different ways. If the point change causes a silent mutation then it doesnt affect at all. When the point nucleotide change make a different amino acid, then it may alters the function of protein. If it make to forma a stop codon (TAA, TAG, TGA) then the protein synthesis stops at the point where it is changed.
What are found in the DNA?
DNA nucleotides. Note that adenine, thymine, cytosine and guanine are NOT nucleotides, but they are only the bases which make the nucleotides different.
Which base is only found in RNA nucleotides?
Uracil is only found in RNA nucleotides. In DNA uracil is replaced by thymine.
What produces a nonsense mutation?
A nonsense mutation is a genetic mutation in a DNA sequence that leads to the appearance of a stop codon where previously there was a codon specifying an amino acid. DNA is a chain of many smaller molecules called nucleotides. During protein formation, DNA (or RNA) nucleotide sequences are read three nucleotides at a time in units called codons, and each codon corresponds to a specific amino acid or stop codon, which is also called nonsense codon because it does not code for an amino acid and instead signals the end of protein synthesis. Therefore, nonsense mutations occur when a premature nonsense or stop codon is introduced in the DNA sequence. When the mutated sequence is translated into a protein, this premature stop codon results in the production of a shortened, and likely nonfunctional, protein.
Is strand of nucleotides in the RNA or DNA?
Both, but RNA sometimes only has 1 side of unpaired nucleotides.
