So That's Why It's Called The Control Center

What three components make up a nucleotide?

Adenine, phosphate, and sugar

Amino acids, phosphate, and sugar

Nitrogenous bases, phosphate, and sugar

Adenine, guanine, and cytosine

What does DNA stand for?

Deoxyribose acid

Deoxyribonuleic acid

Amino acid

Deoxyribose sugar

Why does DNA replicate?

DNA is required for the cell to undergo mitosis.

To take over the cell.

To exit the nucleus into the cytoplasm.

To exit or leave the cell.

What are helicase, DNA polymerase, and DNA ligase examples of?

Sugars

Bases

Polypeptide

Enzymes

What is the end goal of transcription and translation, and where do they occur?

To make protein; transcription takes place in the cytoplasm and translation takes place in the nucleus

To make protein; transcription takes place in the nucleus and translation takes place in the cytoplasm

To make enzymes; transcription takes place in the nucleus and translation takes place in ribosomes

Who came up with the complementary base pair rule and what bases pair together in DNA?

Erwin Chargaff; adenine with thymine; cytosine and guanine

Francis Crick; thymine and adenine; guanine and cytosine

Francis Crick; thymine and cytosine; guanine and adenine

Erwin Chargaff; cytosine and thymine; adenine and guanine

What are the three major steps of DNA replication?

Polymerase unzips, ligase brings new bases, and helicase bonds the bases.

Helicase unzips, then polymerase brings new bases, and finally ligase bonds the bases together

Nucleotides bond, sugars separate, and phosphates are removed.

Ligase unzips, helicase brings in new bases, and polymerase bonds the bases.

How does the makeup of RNA differ from the makeup of DNA?

RNA is smaller than DNA and has less components.

RNA is larger than DNA and has more components.

RNA has Uracil insted of Thymine and RNA is a single helix.

RNA has Adenine instead of Thymine and is a single helix.

What are the different types of RNA and what do they stand for?

MRNA, tRNA, and rRNA and they stand for messenger RNA, transfer RNA, and ribosome RNA.

MRNA, rRNA, and sRNA and they stand for messenger RNA, transfer RNA, and synthesis RNA.

MRNA, tRNA, and rRNA and they stand for messenger RNA, translation RNA, and ribosome RNA.

NRNA, tRNA, and rRNA and they stand for negative RNA, transfer RNA, and ribosome RNA.

What's the end product of DNA replication?

Two unidentical strands of DNA.

Two completely new strands of DNA.

One old strand of DNA and one brand new strand of DNA.

Two identical strands of DNA.

What bonds exist between amino acids during translation?

Hydrogen bonds

Covalent bonds

Peptide bonds

Ionic bonds

How is DNA read?

In a three letter sequence called a codon.

In a four letter sequence called a codon.

In a two letter sequence called a codon.

In a five letter sequence called a codon.
