DNA
What are the four DNA bases?
Adenine, Guanine, Cytosine, Thymine
number of strands RNA is composed of
1
PROCESS OF DNA --> RNA THAT OCCURS IN THE NUCLEUS
WHAT IS TRANSCRIPTION?
TYPE OF MUTATION RESULTS FROM A SINGLE BASE CHANGE
POINT MUTATION/ substitution
name of two big letters. Ex. AA
homozygous dominant
Structure of DNA
double helix
BASE THAT iS UNIQUE TO RNA
What is uracil?
PROCESS OF RNA --> PROTEIN THAT OCCURS IN THE CYTOPLASM OR ON THE ROUGH ENDOPLASMIC RETICULUM
WHAT IS TRANSLATION?
Mutations that shift the codon frame and cause detrimental changes to the amino acid sequence
WHAT IS INSERTION OR DELETION?
name of two little letters. Ex. aa
homozygous recessive
where DNA is found in a cell
What is the nucleus?
What is the name of the sugar in RNA?
Ribose
site of transcription
nucleus
define mutation
a change in DNA
two different alleles within a genotype. ex. Aa
heterozygous
TYPE OF BONDS BETWEEN BASES IN THE DNA HELIX
Hydrogen bond
TYPE OF RNA that takes the message from the nucleus to the ribosome.
mRNA
site of translation
cytoplasm/ ribosome
MUTATION THAT DOES NOT RESULT IN A CHANGE IN THE PROTEIN SEQUENCE
WHAT IS A SILENT MUTATION?
Show a cross between a homozygous dominant and a heterozygous parent. What is the genotypic probability of having homozygous recessive offspring?
0%
Parts of a nucleotide
Sugar, phosphate, nitrogenous base
Organelle that reads mRNA to configure amino acids into a protein
ribosome
Draw a diagram depicting the central dogma of genetics.
DNA->RNA->Protein
Name of a mutation that creates a premature stop codon.
nonsense
Show a cross between a homozygous dominant and a heterozygous parent. What is the phenotypic probability of having offspring with the dominant trait?
100%
