Biology protein synthesis
How many NUCLEOTIDES in mRNA are needed to code for 4 amino acids.
12
During Replication, a DNA strand with following bases CTA-GGT will produce a DNA Strand with bases:
GAT-CCA
Which of the following is a characteristic of RNA but not DNA?
single stranded
Which of the following processes occurs when DNA unwinds, unzips, and one strand of the DNA serves as a template to make one strand of mRNA?
transcription
Before translating a strand of mRNA, you should always check the title of the amino acid chart to determine if it is a chart of codons or anticodons.
true
Which of the following represents the codons in mRNA that correspond to this segment of DNA: TAT-CAG-GAT?
AUA-GUC-CUA
Another name for a protein is what?
poly peptide
Put the following processes of protein synthesis in the correct order.
-The two DNA strands unwind, unzip, and separate. -A strand of mRNA is created by RNA Polymerase. -The mRNA strand leaves the nucleus. -The mRNA strand is read by a ribosome which calls for the correct tRNA molecule. -The tRNA anticodon binds to the corresponding mRNA codon and delivers the correct amino acid. -The amino acids bind to each other; the amino acid chain lengthens; a protein is formed.
Match the # in the diagram with the correct word or words.
1-amino acid 2-polypeptide 3-tRNA 4-codon
