PBS 2.2.2 Protein Synthesis

Front

What is the role of mRNA in protein synthesis?

Back

mRNA (messenger RNA) carries the genetic information from the DNA in the nucleus to the ribosome, where proteins are synthesized.

Front

Where does mRNA synthesis occur in the cell?

Back

mRNA synthesis occurs in the nucleus.

Front

What are the nitrogen bases found in DNA?

Back

The nitrogen bases in DNA are Adenine (A), Thymine (T), Cytosine (C), and Guanine (G).

Front

What is the sugar-phosphate backbone?

Back

The sugar-phosphate backbone is the structural framework of nucleic acids, consisting of a sugar molecule and phosphate groups.

Front

What is the complementary base pairing rule in DNA?

Back

In DNA, Adenine pairs with Thymine (A-T) and Cytosine pairs with Guanine (C-G).

Front

What is the function of ribosomes in protein synthesis?

Back

Ribosomes are the sites of protein synthesis, where mRNA is translated into amino acid sequences.

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.

Front

What amino acid does the codon AUG represent?

Back

The codon AUG represents the amino acid Methionine, which also serves as the start codon.

Front

What is the process of translation?

Back

Translation is the process by which ribosomes read the mRNA sequence and synthesize proteins by linking amino acids together.

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.
