Protein Synthesis

Front

What is the role of DNA in protein synthesis?

Back

DNA holds the genetic code that determines the sequence of amino acids in proteins.

Front

Which nitrogenous base is NOT found in RNA?

Back

Thymine is not found in RNA; it is replaced by Uracil.

Front

Where does transcription of DNA to mRNA occur?

Back

Transcription occurs in the nucleus of the cell.

Front

What is the triplet of bases on the end of a tRNA molecule called?

Back

The triplet of bases on tRNA is called an Anticodon.

Front

What is the function of rRNA?

Back

rRNA combines with proteins to form ribosomes, which are essential for protein synthesis.

Front

What are the three types of RNA involved in protein synthesis?

Back

The three types of RNA are mRNA (messenger RNA), tRNA (transfer RNA), and rRNA (ribosomal RNA).

Front

What is the process of translating mRNA into a protein called?

Back

The process is called Translation.

Front

What is the significance of the codon in mRNA?

Back

A codon is a sequence of three nucleotides in mRNA that specifies a particular amino acid.

Front

How many amino acids are there in the genetic code?

Back

There are 20 different amino acids in the genetic code.

Front

What is the start codon for protein synthesis?

Back

The start codon is AUG, which codes for the amino acid Methionine.
