Molecular Genetics Review

Front

What is the role of tRNA in protein synthesis?

Back

tRNA (transfer RNA) carries amino acids to the ribosome, where proteins are synthesized.

Front

What are the components of the DNA ladder?

Back

The steps of the DNA ladder are made of nitrogen bases (adenine, thymine, cytosine, and guanine).

Front

What is the function of mRNA?

Back

mRNA (messenger RNA) carries the genetic code from DNA to the ribosome for protein synthesis.

Front

Who is known for taking the critical image that helped discover the structure of DNA?

Back

Rosalind Franklin took the critical X-ray diffraction image that contributed to the discovery of DNA's double helix structure.

Front

What type of RNA makes up the ribosome?

Back

rRNA (ribosomal RNA) is the type of RNA that makes up the ribosome.

Front

Define DNA.

Back

DNA (deoxyribonucleic acid) is the molecule that carries the genetic instructions for life.

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 process of transcription?

Back

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

Front

What is the role of rRNA in protein synthesis?

Back

rRNA (ribosomal RNA) forms the core of the ribosome's structure and catalyzes 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.
