Total questions: 13
Worksheet time: 7mins
Which of the following is found in the cells of all living things?
chloroplasts
nucleus
mitochondrion
genetic material
Which of the following molecules holds the information needed to direct cellular processes?
phenylalanine
adenosine triphosphate
chlorophyll
deoxyribonucleic acid
The information in DNA is written according to the genetic code and carried by the -
sequence of nitrogen bases/nucleotides
direction of the phosphate groups
hydrogen bonds between nitrogen bases
enzymes which unwind the double helix
The genetic code describes the way that information is coded in DNA. This code is -
unique to organisms like a fingerprint
similar between closely related organisms
determined by organism’s environment
the same among all living organisms
What do we call the shape a DNA molecule takes?
double-stranded
double helix
sugar-phosphate backbone
pentagon
What are the names of the large structures of DNA which are used to package the genetic information within cells?
enzymes
ribosomes
chromosomes
vitamins
The genetic code seems to suggest that all organisms are related. This conclusion is based on the fact that –
all living things have unique coding systems
each species has some form of a code
every living thing uses the same code
living things pass DNA to offspring
The genetic code is used for translating the information from DNA into a protein. This means that sequences of nucleotides are used to determine the sequences of -
disaccharides
amino acids
carbohydrates
glycerols
Which of the following is the correct pairing of nitrogen bases?
A-T, G-C
A-G, T-C
A-C, G-T
A-A, T-T
What is the appropriate base pairing sequence to match this strand?
5' ATGTTCACT 3'
3' ATGTTCACT 5'
3' TACAAGTGA 5'
3' TCACTTGTA 5'
3' ATGTTGAGT 5'
What are the three components of a nucleotide?
phosphate group, sugar, nitrogen base
phospate group, water, nitrogen base
glycerol, sugar, nitrogen base
adenine, thymine, cytosine
What is the outside of the DNA called?
sugar-phosphate backbone
sugar-phosphate skeleton
sugar-phosphate scapula
sugar-phosphate humerus
True or False: The genetic code is different for every organism.
True
False
