Which does not occur during translation?
trna pairs with complementary mrna.
a peptide bond is created between amino acids.
dna is transcribed into a complementary strand of mrna.
a chain of amino acids, linked by peptide bonds, is formed.

DNA is transcribed into a complementary strand of mRNA.

Explanation:

DNA stores genetic information. During protein synthesis, the genetic information transcribed of DNA is transcribed into a complementary strand of mRNA in the nucleus of a cell. This process is called transcription. The mRNA then moves in the cytoplasm where codons on mRNA sequence translate into a polypeptide by linking a chain of amino acids by peptide bonds.  

chromosomes carry the genetic information for organisms. also, chromatin is the thread like dna which is located in the nucleus of an organism.

c. earths continental crust is thicker than its lithosphere.

because, the lithosphere is the outermost layer of the earth/ 100 km thick and is defined by its machanical properties.the lithosphere contains oceanic and continental crust that varies in age and thickness across locations and geologic time. the lithosphere is the coolest layer of the earth in terms of temperature. the term lithosphere should not be confused with the use of "geosphere" which is used to indicate all of earth systems, including the atmosphere, hydrosphere   and biosphere. the surface of the earth can be divided into the continental crust and the oceanic crust.   the continental crust is made mostly of granite while the oceanic crust is made of basalt. the average thickness of the continental crust is 25 miles and the average thickness of the oceanic crust is 5 miles.   three types of rock, igneous, sedimentary, and metamorphic, make up the surface of the earth. that's why 3 option is preferable.
