Stake Test 4

In reproductive cloning, the genome of the clone comes from?

A body cell

The flow of molecular info in gene expression

Central dogma

What types of bond keeps each individual DNA strand together?

Covalent bonds

In gel electrophoresis of DNA, diff. Brands in final gel form because?

DNA have different lengths

What enzyme can repair damage in eukaryotes?

DNA polymerase

What enzyme is responsible for putting primers down during DNA replication?

DNA polymerase

Why does a liver cell look different from a brain cell?

Different genes are turned on and off in each cell

What proteins are crucial for creating and maintaining DNA replication forks?

Helicase creates the replication fork; single-stranded binding proteins keep the single strands from reuniting

What type of bond keeps each complementary DNA strands together?

Hydrogen bonds

Which of the following is found in eukaryotic genes, but not prokaryotic?

Introns

Three types of RNA involved in gene expression?

MRNA, tRNA, rRNA

How do homologous chromosomes prevent disease?

One homologous can replace the other

DNA replication is semi-conservative bc a newly replicated, double stranded DNA molecule consists of

One old strand and one new strand

What is the purpose of careful primer design before PCR?

Primers dictate the specificity of the place you are amplifying and primers allow for complimentary nucleotides to be added to the new strand of DNA

Part of gene where RNA polymerase first binds during transcription?

Promoter

RNA primer

Provides a place for DNA

What enzyme is responsible for putting down primers during DNA replication?

RNA primase

What determines a protein's function?

The 3D shape of the folded protein

What parts of translocation will be disrupted by a mutation in the coding region of gene?

The codon of mRNA

Gene expression refers to what process?

The process of transcription going DNA into RNA and translating RNA into protein

What controls the timing of gene expression?

The regulatory sequence for a gene

Process of RNA using a gene as a template is

Transcription
