Front

What are the three components of a nucleotide?

Back

sugar, phosphate, nitrogen base

Front

Which two molecules form the sides (backbone) of the DNA ladder?

Back

deoxyribose sugar and phosphate

Front

Who are the two scientists credited with deducing the double helix model of DNA?

Back

Watson and Crick

Front

What determines the code of a DNA molecule?

Back

the order (sequence) of the nitrogen bases

Front

What is the function of RNA in protein synthesis?

Back

RNA acts as a messenger carrying instructions from DNA for controlling the synthesis of proteins.

Front

What are the main types of RNA?

Back

mRNA (messenger RNA), tRNA (transfer RNA), rRNA (ribosomal RNA)

Front

What is the role of mRNA in the cell?

Back

mRNA carries the genetic information from DNA to the ribosome, where proteins are synthesized.

Front

What is transcription in the context of DNA and RNA?

Back

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

Front

What is translation in the context of protein synthesis?

Back

Translation is the process where ribosomes create proteins based on the sequence of mRNA.
