DNA & Protein Synthesis (CCSP)

Front

What is a codon?

Back

A codon is a three-base sequence of mRNA that codes for a single amino acid.

Front

What is the result of DNA replication?

Back

DNA replication results in two DNA molecules, each with one new strand and one original strand.

Front

What are the monomers of DNA?

Back

The monomers of DNA are nucleotides.

Front

What codon is always found at the beginning of an mRNA code?

Back

The codon AUG is always found at the beginning of an mRNA code.

Front

What holds the two strands of DNA together?

Back

The two strands of DNA are held together by hydrogen bonds.

Front

What is the structure of DNA?

Back

DNA is a double helix composed of two strands of nucleotides.

Front

What are the components of a nucleotide?

Back

A nucleotide consists of a phosphate group, a sugar (deoxyribose), and a nitrogenous base.

Front

What are the four nitrogenous bases in DNA?

Back

The four nitrogenous bases in DNA are adenine (A), thymine (T), cytosine (C), and guanine (G).

Front

How do DNA and RNA differ?

Back

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

Front

What is transcription?

Back

Transcription is the process of copying a segment of DNA into mRNA.
