Exam Questions and CORRECT Answers
Transcription - CORRECT ANSWER - (genetics) the organic process whereby the DNA
sequence in a gene is copied into mRNA
Translation - CORRECT ANSWER - Process by which mRNA is decoded and a protein is
produced
codon - CORRECT ANSWER - A specific sequence of three adjacent bases on a strand of
DNA or RNA that provides genetic code information for a particular amino acid
promoter - CORRECT ANSWER - specific region of a gene where RNA polymerase can
bind and begin transcription
RNA transcript - CORRECT ANSWER - RNA molecule produced by transcription that is
complementary to one strand of DNA
RNA polymerase - CORRECT ANSWER - Enzyme similar to DNA polymerase that binds
to DNA and separates the DNA strands during transcription
What direction is RNA synthesized - CORRECT ANSWER - 5' to 3'
TATA box - CORRECT ANSWER - A promoter DNA sequence crucial in forming the
transcription initiation complex.
Transcription factors - CORRECT ANSWER - Collection of proteins that mediate the
binding of RNA polymerase and the initiation of transcription.
What is added in RNA processing? - CORRECT ANSWER - 5' cap and poly-A tail
, RNA splicing - CORRECT ANSWER - Process by which the introns are removed from
RNA transcripts and the remaining exons are joined together.
spliceosome - CORRECT ANSWER - cut out introns and have snRNP inside
pre-mRNA - CORRECT ANSWER - a form of messenger RNA that contains both introns
and exons
tRNA - CORRECT ANSWER - transfer RNA; type of RNA that carries amino acids to the
ribosome
What are tRNAs held together by? - CORRECT ANSWER - Hydrogen bonds
Anticodon - CORRECT ANSWER - group of three bases on a tRNA molecule that are
complementary to an mRNA codon
aminoacyl-tRNA synthetase - CORRECT ANSWER - During protein synthesis, an
enzyme that attaches the correct amino acid to a tRNA molecule to form a "charged" aminoacyl-
tRNA.
Ribosome Anatomy - CORRECT ANSWER - APE
where are the amino acids bonded together in the ribosome - CORRECT ANSWER -P
slot
GTP - CORRECT ANSWER - A nucleotide composed of guanine, ribose, and three linked
phosphate groups. It is incorporated into the growing RNA chain during synthesis of RNA and
used as a source of energy during synthesis of proteins
