Protein Synthesis 2
One DNA strand has a base sequence GTCCATA. The base sequence of the mRNA strand is...
What is CAGGUAU?
The instructions for making proteins are contained here.
The matching mRNA sequence to this piece of a DNA: ACTGAG.
What is UGACUC?
This process turns mRNA into a protein.
What is translation?
What is a mutation?
What is any change to an organism's DNA/genome.
The 3 parts of RNA.
What is a phosphate group, sugar (ribose), base (A, C, U, or G)?
The end product of translation.
What is a protein?
This is made during transcription.
What is mRNA?
This cell organelle makes protein.
What is a ribosome?
What is a frameshift mutation?
What is a mutation that occurs when a base is inserted or deleted?
A sequence of DNA nucleotides that codes for a specific protein.
What is a gene?
The building blocks of proteins.
What are amino acids?
Why can’t DNA leave the nucleus?
DNA is too long/bulky to exit through the nuclear pores.
A 3 nucleotide sequence on mRNA that matches to a specific amino acid.
What is a codon?
A chemical or physical agent in the environment that can change DNA.
What is a mutagen?
The two processes of protein synthesis.
What are transcription and translation?
How many nitrogen bases are needed to code for 5 amino acids?
What is 15 nitrogen bases? (5x3=15)
This type of RNA brings amino acids to the ribosome and holds the anticodons for each.
What is tRNA?
Going from CATCATCAT to CATCTTCAT is called this.
What is a substitution or point mutation?
A change in the genetic material of a cell.
What is a mutation?
The amino acid that is coded by CAU.
What is His?
This type of RNA is found in a ribosome.
What is rRNA?
Transcription occurs in this part of the cell.
What is the nucleus?
What is the significance of mutations to living things?
What is: mutations are a source of genetic variations. Some variations help organisms adapt to different or changing environments. Mutations are necessary for organisms to evolve.
