DNA/Protein Synthesis SOL

Front

What is the significance of nitrogenous bases in DNA?

Back

The order of nitrogenous bases determines the order of amino acids in the proteins synthesized.

Front

What is the purpose of Strand A in DNA?

Back

To act as a template for the synthesis of messenger RNA.

Front

What percentage of offspring will be colorblind if colorblindness is a recessive, X-linked disorder?

Back

50%.

Front

Which DNA strand is complementary to the top one shown in a diagram?

Back

C.

Front

What evidence suggests that the environment can influence gene action?

Back

Prolonged exposure to sunlight results in increased pigment production in skin cells (tanning).

Front

What are the four nitrogenous bases found in DNA?

Back

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

Front

What is the role of messenger RNA (mRNA) in protein synthesis?

Back

mRNA carries the genetic code from DNA in the nucleus to the ribosome for protein synthesis.

Front

What is a codon?

Back

A codon is a sequence of three nitrogenous bases in mRNA that codes for a specific amino acid.

Front

What is the function of transfer RNA (tRNA)?

Back

tRNA picks up and transfers specific amino acids to the ribosome during protein synthesis.

Front

What is the difference between DNA and RNA?

Back

DNA is double-stranded and contains thymine, while RNA is single-stranded and contains uracil instead of thymine.
