Genes are traits
A gene and the expression of the gene as a characteristic or trait are the same thing
There are some types of organisms that do not have DNA
Only animals have DNA, plants and mushrooms do not have DNA
Each DNA molecule is made of more than one chromosome
The different cell types found in a given individual’s body contain different DNA
Genes are responsible for inherited characteristics with no realisation of their role in
protein synthesis
DNA physically produces proteins when required
The assumption that the non-coding strand of DNA should not transcribed to mRNA
Disregard for the role of enzyme in the transcription of mRNA
Addition of uracil is random
Enzymes cause a permanent change in DNA and new DNA needs to be reproduced
Amino acids enter through the nuclear pores similar to nucleotides
Amino acids are aligned with mRNA strand through trial and error similar to the
jigsaw activity
That DNA, in this helical structure, will stay straight and upright, that it won’t coil
up around itself and other DNA molecules in order to fit in the nucleus of the cell
That the bases can bond to any that they choose, that they do not follow rules
regarding bonding
Structure of the nucleotides
Hydrogen bonding being the only type of bonding that occurs in DNA molecules
Genetic code can be read using a microscope
Genetic code is only ever found in one sequence, without variation
DNA replication occurs in prophase during the process of cell division
DNA replication occurs between prophase and metaphase during the process of cell
division
The chromosome number is doubled in the prophase of mitosis and halved in the
anaphase of mitosis
A gene and the expression of the gene as a characteristic or trait are the same thing
There are some types of organisms that do not have DNA
Only humans contain DNA
DNA is made of protein
Genes contain alleles. Alleles contain genes.
Genes and alleles are the same
DNA replication occurs in prophase
Specialised sex cells contain the same number of chromosomes as normal body cells
Genes are proteins
Each cell only contains specific genetic information required to fulfil its function
DNA is found in sex cells but not in any other types of body cells
