Correctly Solved Questions Update 2023
GENE - Exact Answer: a segment of DNA that is used to make a RNA
molecule or a polypeptide
TRANSCRIPTION - Exact Answer: synthesizing RNA from a DNA template
PROTEIN ENCODING GENES - Exact Answer: carry the information from
the amino acid sequence of a polypeptide
mRNA - Exact Answer: the initial product of transcription; a temporary
copy of a gene that contains information to make a polypeptide
DNA REPLICATION - Exact Answer: making DNA copies that are
transmitted from cell to cell and from parent to offspring
POLYPEPTIDE - Exact Answer: a linear sequence of amino acids that is
the product of mRNA translation; one or more-fold to form a functional
protein
GENE EXPRESSION - Exact Answer: the overall process by which the info
w.in a gene is used to produce a functional product

Correctly Solved Questions Update 2023
REGULATORY SEQUENCES - Exact Answer: site for the binding of
regulatory proteins
REGULATORY PROTEINS - Exact Answer: influence the rate of
transcription
PROMOTER bacteria - Exact Answer: site for RNA polymerase binding;
initiates transcription; -35 and -10 sequences
PROMOTER eukaryotes - Exact Answer: site for RNA polymerase
binding; initiates transcription; core promoter consists of a TATA box
and transcriptional start site
TERMINATOR - Exact Answer: a sequence w.in a gene that signals the
end of transcription
RIBOSOME-BINDING SITE - Exact Answer: site on mRNA for ribosome
binding; translation begins near this site

Correctly Solved Questions Update 2023
CODON - Exact Answer: 3 nucleotide sequence w.in mRNA that
determines the sequence of amino acids w.in a polypeptide
RNA POLYMERASE bacteria - Exact Answer: an enzyme that synthesis a
strand of RNA using a DNA strand as a template
RNA POLYMERASE eukaryotes - Exact Answer: three types, RNA poly 1,
2 and 3 transcribes protein-encoding genes
RIBOSOME - Exact Answer: a large macro-molecule structure that acts
as the catalytic site for polypeptide synthesis; allows mRNA and tRNA to
be positioned correctly as the polypeptide is made
SMALL NUCLEAR RNA - Exact Answer: found in high amounts in the
nucleolus and promote the covalent modification of rRNAs
TRANSFER RNA - Exact Answer: molecules that act as temp carriers of
amino acids, bringing the appropriate amino acids to the ribosome
based on the mRNA
