1
The production of gametes involves this type of cell division
Mitosis
Meiosis
Moronitis
Memorosis
2
If 2 heterozygous parents have a child, the chance of it having the recessive phenotype is:
100%
75%
50%
25%
3
If a protein has 12 amino acids, how many DNA bases are in the gene?
4
6
72
36
4
In flowering plants the gametes are called
Pollen and Ovules
Pollen and Ova
Sperm and ova
Sperm and Ovules
5
Reproductive organs in humans are known as:
Both answers
Testes
Neither answer
Ovaries
6
Where does protein synthesis occur in cells?
Ribosomes
Romanians
Ribulose
Robotics
7
One difference between Meiosis and Mitosis:
Meiosis forms 4 daughter cells, mitosis forms 2
Meiosis forms sex cells, mitosis forms naughty cells
Meiosis forms body cells, mitosis forms egg cells
Meiosis forms offspring, mitosis forms mutants
8
A mutation can be caused by:
A spontaneous change in the base sequence
Ionising radiation affecting DNA replication
All of the above
A chemical mutagen such as particulates or tar in cigarettes
9
Sexual reproduction introduces genetic variation to a species.
True
False
10
DNA stands for:
Deoxyribonucleic Apples
Deoxidised Nitric Acid
Deregulated Nuclear Activity
Deoxyribonucleic Acid
11
The genetic code...
...provides the instructions for making proteins
...provides the recipe to make really delicious desserts
...provides the OS for writing complex computer code
...provides the information needed to avoid ugly offspring
12
The definition of a genome is:
All of the genetic material of that organism
A section of chromosome that codes for a protein
All of the cell organelles of an organism
The offspring of a genetically modified gnome
13
When a mutation occurs, what could happen to the protein coded for by that gene?
It may be left in the muscle cells to make them contract
It might not be the right shape to carry out its function
It might be digested by enzymes in the stomach
It could be passed on to the offspring to reproduce
14
What is the cause of polydactyly?
A recessive allele for the size of the hands and feet
A dominant allele for the number of digits
A recessive allele for the number of digits
A dominant allele for the size of the hands and feet
15
Genetic testing methods involve:
All of these answers
Preimplantation Genetic Diagnosis (PGD)
Amniocentesis
Chorionic Villus Sampling (CVS)
16
The structure of DNA can be described as
A double helix
A section of a genome
A chromosomal anomaly
A twisted ladder of jelly babies
17
The sex of an individual is determined by
the inheritance of XX or XY chromosomes
the Punnett square diagram being correct
the ability to play ball sports and musical instruments
the level of attractiveness of their parents
18
Define the term homozygous
Genome contains two of the same alleles for that gene
Cell that looks the same as all other cells in that tissue
Cell that contains two different alleles for that gene
Genome that has more than one gene for each characteristic
19
The fusion of gametes in human cells (fertilisation)...
...causes the chromosome number to be halved
...causes the chromosome number to be doubled
...causes the chromosome number to be restored to normal
...causes chromosomes to become more visible
20
Asexual reproduction involves the joining of male and female gametes
True
False
