DNA, RNA and protein synthesis

Front

What is the role of tRNA in translation?

Back

tRNA (transfer RNA) carries amino acids to the ribosome and matches them to the codons on mRNA during protein synthesis.

Front

What is the complementary DNA strand for the sequence CGTACTTGATCA?

Back

GCATGAACTAGT

Front

What is the complementary mRNA sequence for the DNA segment CGTACTTGATCA?

Back

GCAUGAACUAGU

Front

How are proteins formed?

Back

Proteins are formed when a string of amino acids fold into a specific, complex 3-dimensional structure.

Front

What is one key difference between RNA and DNA?

Back

RNA is single-stranded, while DNA is double-stranded.

Front

What base does RNA have that DNA does not?

Back

Uracil (U) replaces Thymine (T) in RNA.

Front

What is the function of ribosomes in protein synthesis?

Back

Ribosomes are the cellular machinery that facilitate the translation of mRNA into a polypeptide chain (protein).

Front

What is a codon?

Back

A codon is a sequence of three nucleotides on mRNA that corresponds to a specific amino acid.

Front

What is the process of transcription?

Back

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

Front

What is the significance of the genetic code?

Back

The genetic code is a set of rules that defines how the sequence of nucleotides in DNA and RNA is translated into the sequence of amino acids in proteins.
