CHAPTERS 16 & 17: From DNA to Proteins (Polypeptides)

Front

What did Griffith observe in his transformation experiments?

Back

Mixing a heat-killed pathogenic strain of bacteria with a living nonpathogenic strain can convert some of the living cells into the pathogenic form.

Front

What are the first six nucleotides of the complementary RNA strand to the DNA strand: ATA CGT?

Back

UAU GCA

Front

What holds the nitrogenous bases together in DNA?

Back

Hydrogen bonds.

Front

What best describes mRNA?

Back

It is a temporary copy of a DNA gene.

Front

What is the process of copying DNA during the cell cycle called?

Back

Replication.

Front

What are the building blocks of DNA?

Back

Nucleotides.

Front

What are the four nitrogenous bases in DNA?

Back

Adenine (A), Thymine (T), Cytosine (C), Guanine (G).

Front

What is the role of RNA polymerase in transcription?

Back

RNA polymerase synthesizes RNA from a DNA template.

Front

What is the difference between DNA and RNA?

Back

DNA contains deoxyribose sugar and is double-stranded; RNA contains ribose sugar and is single-stranded.

Front

What is the function of ribosomes in protein synthesis?

Back

Ribosomes are the sites where translation occurs, synthesizing proteins from mRNA.
