Anticodons – Microbiology Mid Exam
The key terms of Microbiology Mid Exam include, Anticodons.
What kind of molecule carries anticodons?
rRNA
tRNA – correct
mRNA
DNA
What is the function of RNA polymerase?
synthesize a strand of DNA following an RNA template
synthesize a molecule of RNA using DNA template – correct
make a protein
replicate RNA molecules
What is an operon?
a cluster of gene with related function that are co-regulated – correct
site of protein synthesis
non-coding regions in genes
site where RNA polymerase can bind to the DNA
Gene that are normally ‘on’ but can be turned ‘off’ are
constitutive
none of these
inducible
repressible – correct
DNA replication is semi-conservative. That means that daughter molecules
both daughter molecules contain a mixture of old and new DNA in both strands
are iddferent in that one caontains the old strands and one contains the newly synthesized strands
contains one oreiginal and one newly synthesized strand – correct
none of these
DNA polymerase will synthesize a new strand of DNA in one direction only; 5′ to 3′.
True – correct
False
At each replication fork, one new strand gets synthesized faster than the other.
True – correct
False
What is the function of DNA?
deliver amino acids to the ribosome
carry information from the nucleus to the ribosom
to carry information, usually recipes for the primary structure of proteins – correct
none of these
How do DNA and RNA molecules differ?
number of strands; 1 or 2
base pairing
pentose
all of these – correct
What is the function of the promoter region of a gene or operon?
the start of translation
the start of transcription
site where RNA polymerase can bind to the DNA – correct
regulates rate of transcription
What is an intron?
transposons
the coding regions within a gene
a none coding region within a gene – correct
mutations
What is the function of tRNA?
to deliver amino acids to the ribosome – correct
transfer information from the nucleus to the ribosome
part of the ribosome structure
store the recipes for proteins
