What can occur as a result of a change in the sequence of nucleotides in a strand of DNA?
The addition or deletion of a nucleotide can lead to a Frameshift mutation. The Frameshift mutation causes a "shift" in the reading frame of the codons in the mRNA. This may lead to the change in the amino acid sequence at protein translation.
An okazaki fragment has which of the following arrangements?
5' DNA to 3' Bipin
What are the two major functions that DNA polymerase performs?
DNA Polymerases are responsible for the addition of nucleotides to the new strand of DNA, and for replacing the RNA primers.
What attaches free nucleotides to the growing DNA strand?
During DNA replication, DNA polymerase binds free DNA nucleotides to an unzipped DNA strand. During transcription, RNA polymerase binds free RNA nucleotides to the unzipped anti-sense DNA strand.
How many bases on a strand of mRNA code for one amino acid?
3 nucleotides

What are the three types of mutation?
The three types of Mutations are: Substitution Deletion Addition For example: Mutation stand to compare back to: ATG CAT AGG Mutation#1: ATT CAT AGG It is Substitution in this strand because the "G" was changed to a "T." Mutation#2: ATG ATA GG It is Deletion in this strand because the "A" was deleted. Mutation#3: ATG CAT TAGG It is Addition in this strand because another "G" was added to the end of the strand.
Is DNA a single strand of nucleotides?
No, DNA, from difference with the RNA, is a double strand of nucleotides. DNA, double strand (hence the double helix nickname). RNA, single strand.
An okazaki fragment has which of the following arrangements?
5' DNA to 3' Bipin
What type of bond is between nucleotides?
In producing a strand of DNA the nucleotides combine to form phosphodiester bonds.
Is strand of nucleotides in the RNA or DNA?
Both, but RNA sometimes only has 1 side of unpaired nucleotides.
If there are 1200 nucleotides in DNA strand how may codons will be in mRNA strand?
400 codons.Because 3 consecutive nucleotides in a gene together form a codon which codes for amino acids.
What is one role that triphosphate deoxyribonucleotides play in a cell?
Triphosphate deoxyribonucleotides form hydrogen bonds with their complements in a DNA parent strand during transcription of the leading strand of DNA. Example Adenine nucleotides bind to thymine nucleotides Guanine nucleotides bind to Cytosine nucleotides

How many nucleotides would it take to construct the mRNA coding strand of the β-subunit of the hemoglobin A molecule?
441 nucleotides
How many bases on a strand of mRNA code for one amino acid?
3 nucleotides
