DNA
What are the four nitrogenous bases found in DNA?
A, T, G and C
What sugar is found in RNA?
Ribose
Is Bb heterozygous or Homozygous?
Heterozygous
What is a Punnett Square used for?
To show how genes are passed down
What is the shape of the DNA molecule called?
Double helix, ladder, turning staircase, twisted
Which nitrogen base is found in RNA but not in DNA?
U
What is the word used to describe the strong gene?
Dominant
In a cross between two heterozygous (Aa) individuals, what are the possible genotypes of the offspring?
AA - 1
Aa - 2
aa - 1
If one strand of DNA has the sequence A-T-G-C, what is the complementary strand?
T-A-C-G
What does RNA stand for?
Ribo Nucleic Acid
What is the word used to describe the quiet or weak gene?
recessive
If a mom BB and a dad bb have babies, what would be the genotype of the babies?
All would be Bb
What is the function of the DNA?
To store genetic information / codes for traits/ hold the information for the body
If a DNA strand reads A-T-G-C, what would the corresponding RNA sequence be during transcription?
What is the difference between Genotype and Phenotype ?
Phenotype is what you can see, and genotype is the genes in the body.
What does it mean if a trait is dominant?
It is expressed even if only one copy of the allele is present.
A mutation causes one of the base pairs in DNA to change. How might this affect the structure and function of the resulting protein?
Will cause it change/ different amino acid is produced/ change in trait/ the protein will not be able to function.
Why is DNA double stranded and RNA single stranded?
RNA’s single-stranded nature allows it to fold into various shapes and leave the nucleus to perform different roles (e.g., mRNA, tRNA).
What is the difference between Heterozygous and homozygous
Heterozygous means different types of genes Bb
Homozygous means same BB bb
If B is brown hair
and b is red hair.
What color hair would a person with Bb have?
Brown because B is there and it is the strong gene.
