Match the type of RNA to its correct description.
tRNA
A type of RNA that copies DNA.
rRNA
Made of two parts - this type of RNA helps code for amino acids.
mRNA
A type of RNA that helps nucleic acids make amino acids. These amino acids will make proteins.
This enzyme binds to DNA during transcription and separates the DNA strand. A single stand of mRNA can now copy one side of the DNA strand.
DNA Polymerase
RNA Polymerase
Transcriptase
RNA synthesis
A long chain of amino acids is also known as a _________________. These can contain up to 20 different amino acids.
Polypeptide
Polyploidy
codon
anticodon
True or False: A group of three nucleotide bases in mRNA that makes a particular amino acid is known as a codon.
True
False
True or False: Gene expression is the process by which DNA, RNA, and proteins are involved in putting genetic information into action in living cells.
True
False
Match the mutation name to its description.
Substitution
One nucleotide is substituted for another nucleotide.
Deletion
One nucleotide is deleted from the sequence. This shifts the frame and makes it shorter.
Insertion
A nucleotide is inserted, shifting the frame and making it longer.
A chemical or physical agent in the environment that causes a mutation is known as a _________________.
Differentiation
Translation
Transcription
Mutagen
Blocking gene expressions by means of a microRNA (miRNA) silencing complex.
Cell Specialization
Transcription Factors
RNA Interference
Differentiation
Match the following steps in mRNA synthesis.
Introns
A region of DNA that has a specific base sequence.
Exons
Portions that are cut out and discarded.
Promoters
Remaining pieces are spliced back together to form the final mRNA strand.
True or False: Each tRNA molecule has three unpaired bases known as the anticodon.
True
False
Match the chromosomal mutation with its description.
Duplication
All or part of the chromosome is lost.
Translocation
Produces an extra copy of all or part of a chromosome.
Deletion
Reverses the direction of part of a chromosome.
Inversion
Part of one chromosome breaks off and attaches to another.
