Genetics Final Exam Questions and Answers
100% Pass.
The transfer of info from nucleotides in DNA to amino acids in a protein occurs in 2 steps -
answer✔transcription and translation
what is the fate of the introns in pre-MRNA? - answer✔they are discarded
what is true about tRNA - answer✔it brings specific amino acids to ribosomes during translation
2 tRNA molecules occupy sites on a ribosome. The amino acids they carry are joined by a
peptide bond. What happens next? - answer✔the tRNA in the 1st site detaches and leaves the
ribosome
what is true about tRNA and their amino acids? - answer✔any tRNA can carry only 1 type of
amino acid and amino acids attach to the tRNA's at the end opposite the anticodon
What is one difference between amniocentesis and chorionic villus sampling? -
answer✔chorionic villus sampling can be preformed earlier than amniocentesis
how does polyploidy differ from aneuploidy? - answer✔polyploidy involves changes in entire
chromosome sets; aneuploidy involves less than a diploid set of chromosomes
a karyotype does not provide information about what? - answer✔location and type of single
nucleotide substitution mutation
a frameshift mutation is caused by? - answer✔a one-base insertion
PKU is caused by? - answer✔the accumulation of phenylalanine
ribosomes are organelles that function in? - answer✔protein synthesis
in the cell cycle, the G1 phase represents? - answer✔a period of growth
centromeres - answer✔connect sister chromatids and attach chromosomes to spindle fibers
the process of mitosis results in? - answer✔the production of 2 genetically identical cells
