DNA
What shape is DNA?
Double helix
Interphase before cell division,
What are the three types of RNA and what do they do?
mRNA- message
tRNA- transport
rRNA- ribosomal
What is a mutation?
A change in DNA
What are DNA's Base Pairs?
A-T, G-C
Why does dna replication occur?
to make sure the new cells have complete set of DNA
What is produced during transcription?
mRNA
What is a frameshift mutation?
When a nucleotide is inserted or deleted
If Adenine is 10 %, what percentage would guanine be?
40%
What does semiconservative DNA mean?
after dna replication, the two new dna molecules have one old strand and one new strand
What is produced after translation?
Amino acids/ proteins
What is a point mutation?
When a single nucleotide is changed
How are all organism's DNA similar?
They have the same 4 nitrogenous bases
How many nucleotides is in one codon?
3
Describe the relationship between a cell, protein, and dna?
What would a change in the sequence of subunits (nitrogenous bases) in DNA do?
Could lead to a change in protein, no effect, positive or negative.
how is the individuality of an organism determined
What is an anticodon
sets of 3 rna base pairs to help transport mRNA to ribsomes
What would the mRNA base pairs to A-C-G-T-A-C be?
U-G-C-A-U-G
If an mRNA molecule is AGG and which mutated to ACG. Did a change occur? if so describe the change?
amino acid changed from Arginine to threonine
