How many bases are in a base PAIR?
2
Choose the correct statement:
The function of the protein determines the shape
The shape of the protein determines the function
The shape of the protein determines its function
Why do you have two alleles?
One from the sperm (biological father) and one from the egg (biological mother).
gene
sequence
order
Where in the cell are proteins synthesized?
Ribosome
There are only 20 amino acids, so why are there so many proteins?
The sequences of amino acids leads to many different shapes/structures which leads to many different functions.
Say the correct letters used in DNA to RNA transcription
A --> U
G --> C
C --> G
T --> A
Why would a disease which changes the DNA sequence cause a person to not be able to maintain homeostasis.
Because the gene would code for a different RNA which codes for a malfunctioning protein which causes the disease.
What do mutations and alleles have in common?
an allele is a different option for a gene caused by different mutations over generations
DNA location
nucleus
Which represents a DOMINANT genotype
Two capital letters
One capital and one lower case
Both
Neither
Tell me 3 causes of mutations
UV, X ray and Nuclear radiation
mistakes when copying DNA to make new cells for growth and repair
when making eggs and sperm, certain chemicals
T
No - Some have positive effects
ex) lactose tolerance, squirrels changing color to be seen.
What is the correct match for C in the DNA molecule?
C
What are the 2 types of mutations?
Gene and Chromosomal
