Back

DNA is composed of nucleotides, which include a phosphate group, a sugar (deoxyribose), and nitrogenous bases (adenine, thymine, cytosine, guanine).

FLASHCARD QUESTION

Front

What is the role of RNA in protein synthesis?

Back

RNA serves as a messenger between DNA and ribosomes, where proteins are synthesized. It carries the genetic information from the DNA to the ribosomes.

3.

FLASHCARD QUESTION

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.

4.

FLASHCARD QUESTION

Front

What is a codon?

Back

A codon is a sequence of three nucleotides in mRNA that corresponds to a specific amino acid or stop signal during protein synthesis.

5.

FLASHCARD QUESTION

Front

What is transcription in the context of protein synthesis?

Back

Transcription is the process of copying a segment of DNA into mRNA, which then carries the genetic information to the ribosome.

6.

FLASHCARD QUESTION

Front

What is translation in protein synthesis?

Back

Translation is the process where ribosomes read the mRNA sequence and synthesize a corresponding polypeptide chain (protein) by linking amino acids together.

FLASHCARD QUESTION

Front

What is genetic engineering?

Back

Genetic engineering is the manipulation or addition of genes to alter the genetic makeup of an organism.
