Exam 15: Eukaryotic and Archaeal Genome Replication and Expression

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

RNA polymerase II of eukaryotes is responsible for transcribing

The genetic code is translated in groups of __________ bases.

The Pribnow box of

Key sequences exist within promoters,which vary somewhat among various promoters but are sufficiently constant that they can be represented by a sequence of bases most often found at each position.These representations are called __________ sequences.

Bacterial chromosomes,unlike eukaryotic chromosomes,often consist of a single replicon.

Archaeal promoters are most similar to those of

Split or interrupted genes have been found in eukaryotes but not in prokaryotes.

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

Unlike members of the Bacteria,most archaeons have linear chromosomes with multiple origins of replication.

The process by which the base sequence of an RNA molecule is used to direct the synthesis of a protein is called

A complex consisting of a single mRNA molecule with several ribosomes is called a

What is the minimum number of aminoacyl-tRNA synthetase enzymes needed to attach amino acids to all the various tRNA molecules?

Most archaeal mRNAs like those of eukaryotes are spliced.

Because of its larger size,the replication rate of eukaryotic genomes is significantly faster than the replication rate of prokaryotic genomes.

DNA replication is a complex process,and as a result the frequency of error is quite high.

Splicing of eukaryotic heteronuclear RNA is catalyzed by ______________.

The unexpressed regions of split genes are called

A consensus sequence in the untranslated leader sequence of a prokaryotic mRNA which serves as a ribosome binding site is called the __________ sequence.

Many archaeal genomes include plasmids
