What is interphase
What is a period of normal growth and existence of a cell?
Translation of RNA to protein happens here
What is a Ribosome?
What is a genetic mutation?
what is a mutation is any random alteration in the DNA sequence?
DNA is made up of monomers called _________________

How many daughter cells are produced in meiosis, and are they identical?
Meiosis produces four daughter cells. They are genetically unique from each other and the parent cell
DNA is copied into a strand of RNA during this step of protein synthesis.
What is Transcription?
during what stage of the cell cycle is gene mutation most likely to occur
what is interphase - synthesis?
DNA looks like a twisted ladder. Its shape is called ______________________.
double helix
Which of the following is the FIRST step in DNA replication? A. Helicase unzips the double helix B. DNA polymerase proofreads the strand C. DNA polymerase unzips the double helix D. Helicase proofreads the strand
A. Helicase unzips the double helix
The process by which the chromosome number is halved.
What is meiosis?
Anticodons and amino acids are found on this molecule.
What is transfer RNA?
state what is meant by gene mutation
What is change to DNA base sequence?
Each nucleotide has three parts. Name them.
Base, sugar, phosphate
What is a mistake in DNA called?
A mutation
The number of cycles that meiosis goes through.
What is two?
Groups of three bases on a mRNA molecule
What is a codon?
what name is used for the non-coding sections of a gene?
what is a intron?
What is the name of the sugar in DNA?
deoxyribose
What is the name of enzyme responsible for proofreading the final daughter strands?
DNA polymerase
This is placed after the phase to indicate the cycle that it is in.
What is a roman numeral?
This is the anticodon for CAG
What is GUC?
