1.5 DNA and Protein Synthesis

Front

What are the components of a nucleotide?

Back

A nucleotide is made up of three components: a sugar molecule, a phosphate group, and a nitrogen base.

Front

What shape did Watson and Crick propose DNA has?

Back

Watson and Crick proposed that DNA has the shape of a double helix.

Front

What is the function of tRNA in protein synthesis?

Back

tRNA (transfer RNA) carries amino acids to the ribosome during protein synthesis.

Front

What type of RNA is responsible for carrying genetic information from DNA to the ribosome?

Back

mRNA (messenger RNA) carries genetic information from DNA to the ribosome.

Front

What organelle is known as the site of protein translation?

Back

The ribosome is the organelle where protein translation occurs.

Front

What are the four nitrogen bases found in DNA?

Back

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

Front

What is the role of rRNA in the cell?

Back

rRNA (ribosomal RNA) is a component of ribosomes and plays a crucial role in protein synthesis.

Front

How does the structure of DNA relate to its function?

Back

The double helix structure of DNA allows for the efficient storage of genetic information and the precise replication of DNA during cell division.

Front

What is the process of transcription?

Back

Transcription is the process by which the information in a gene is copied into mRNA.

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.
