Exam 13: Bacterial Genome Replication and Expression

Which of the following is the initiator codon?

DNA functions as a storage molecule,holding genetic information for the lifetime of a cellular organism and allowing that information to be duplicated and passed on to its progeny.

In order to add a single amino acid to a growing polypeptide chain,a grand total of __________ molecules or ATP or GTP are utilized.

mRNA molecules have a nontranslated sequence called the __________,which is located downstream of the termination codon.

The region at which the RNA polymerase binds is the __________ region.

Which of the following is not a termination codon?

Messenger RNA molecules that direct the synthesis of more than one polypeptide are said to be __________.

The principle of transformation was first demonstrated by which of the following individuals or groups of individuals?

The Pribnow box of

The process by which the base sequence of all or a portion of a DNA molecule is used to direct the synthesis of an RNA molecule is called

Ribosomes consist of __________ separate subunits that come together as part of the initiation process and dissociate immediately after termination.

The transcribed,but not translated,sequence that is immediately upstream of the region that encodes the functional product is called the __________ region.

The __________ is the collection of characteristics of an organism that an investigator observes.

Prokaryotic DNA replication occurs at a rate of

Which of the following individuals or groups of individuals demonstrated that the transforming principle was DNA?

The energy needed for protein synthesis is provided by the hydrolysis of

Some microbial proteins are spliced after translation in a reaction that results in removal of one or more internal intervening sequences called inteins.

The genetic information in DNA is divided into units called

When a DNA molecule is replicated,the daughter molecules contain one strand of parental DNA and one strand of newly synthesized DNA; this is called __________ replication.

In __________ ribosomes can attach to the mRNA and begin translation even though transcription has not been completed.
