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
