Total questions: 24
Worksheet time: 14mins
The difference between DNA and RNA is
DNA is double stranded while RNA is single
DNA uses A,G,T,C but RNA uses ACGU
DNA is made by the ribosomes and RNA is made by the golgi bodies
_________________is the process of transcribing DNA into MRNA.
TRANSCRIPTION
TRANSLATION
REPLICATION
___________takes information from the nucleus out into the cell.
tRNA
rRNA
mRNA
Which one of these nitrogen bases is not found in RNA?
adenine
thymine
guanine
amino acids can be found on the tRNA floating in the ________of a cell
cytoplasm
nucleus
vacuole
golgi
RNA contains _______instead of deoxyribose like DNA
Phosphate
nitrogenous base
ribose
What are the 3 kinds of RNA?
mRNA, rRNA, tRNA
messenger RNA, ribosomal RNA, transfer RNA
metamorphosis RNA, rock star RNA, templated RNA
Transcription starts in the __________________ of a cell
endoplasmic reticulum
cytoplasm
nucleus
mitochondria
__________is a form of RNA that carries genetic information from the nucleus (DNA) into the cytoplasm
tRNA
rRNA
mRNA
_____________holds the mRNA still so the tRNA can transfer its amino acid
tRNA
rRNA
mRNA
the monomer for a nucleic acid is
fatty acid
glucose
nucleotides
mRNA has _______________, which is a set of 3 nitrogen bases
anti-codon
codon
anti-codon and codon
What is wrong with this strand of mRNA?
ACA TTG GCC ATC GA
it contains Thymine and should contain uracil
there are not enough codons
it is perfectly fine
To determine the amino acid you must
transcribe DNA into mRNA
translate mRNA into amino acids using rRNA and tRNA
transcribe mRNA into DNA
If RNA or DNA is mutated by either deletion or insertion, then DNA/RNA strand will be off from the mutation onward and is called
frameshift
substitution
nonsense
missense
DNA molecule segment is : TTACGCAAG
The mutated DNA segment is TTCGCAAG. This is an example of ___ mutation.
Substitution
Deletion
Insertion
Inversion
Why are insertion and deletion (frameshift) mutations so harmful?
They change all of the codons from the mutation on down the strand, which changes the entire amino acid sequence
They insert things that an organism doesn't need.
They often delete things that organisms need.
Insertion and deletions are not any more harmful than substitution mutations.
