Organelle where genetic material is stored
Nucleus
In the protein synthesis baking analogy, what biological molecule represents the "original recipe"?
DNA
In mRNA, which nitrogenous base replaces Thymine (T)?
Uracil
What is the general definition of a DNA mutation?
What is a change in the DNA base sequence?
What is the basic monomer (building block) of nucleic acids?
nucleotides
Which type of RNA carries the short copy of genetic instructions from the nucleus to the ribosome?
mRNA
Organelle where protein synthesis occurs
Ribosome
Which type of point mutation changes a single nucleotide, resulting in a STOP codon?
nonsense mutation
Name the three specific components that make up every DNA nucleotide.
phosphate group, 5-carbon sugar (pentose), and a nitrogenous base
Carbohydrates, lipids, proteins, and nucleic acids
Name of the strand of DNA that is usually transcribed into mRNA
template strand
Which type of point mutation alters a single base but still codes for the exact same original amino acid?
silent mutation
Unlike the coding strand, the DNA template strand used by RNA polymerase during transcription always runs in this specific prime directional orientation
3' to 5'
Which type of RNA carries and attaches amino acids together during protein assembly?
tRNA
The mRNA sequence for the following DNA strand:
3'- ACTCGATCGTAT - 5'
5' - UGAGCUAGCAUA - 3"
The mutations that are categorized as frameshift mutations
insertion and deletion
The number of individual nucleotides were required to code for a chain of 150 amino acids?
450
This specific type of point mutation occurs when an original mRNA codon 5'- AUA - 3' is altered to 5'- AUG - 3', changing a single amino acid from Isoleucine to Methionine.
Missense mutation
The reason why having access to mRNA "photocopies" advantageous for a cell compared to using the original DNA directly
It protects the original DNA from damage while allowing the cell to edit messages and manufacture multiple proteins simultaneously
Any of the three mRNA STOP codon sequences listed in the genetic code.
UAA, UAG, or UGA
