DNA Replication & Protein Synthesis Retest

Front

What is the process of Transcription?

Back

Transcription is the process by which the genetic information in DNA is copied into messenger RNA (mRNA). This occurs in the nucleus of the cell.

Front

What type of information does DNA carry?

Back

DNA carries genetic information that determines the traits and characteristics of an organism.

Front

When DNA replicates, are the new strands identical or different?

Back

The new strands of DNA are identical to the original strand, ensuring genetic consistency.

Front

Where is protein synthesized in the cell?

Back

Proteins are synthesized in the ribosome, which can be found in the cytoplasm or attached to the endoplasmic reticulum.

Front

What are the four nitrogen bases found in DNA?

Back

The four nitrogen bases in DNA are adenine (A), thymine (T), guanine (G), and cytosine (C).

Front

What is the role of ribosomes in protein synthesis?

Back

Ribosomes are the cellular structures that facilitate the translation of mRNA into proteins by linking amino acids together.

Front

What is the difference between DNA and RNA?

Back

DNA is double-stranded and contains the sugar deoxyribose, while RNA is single-stranded and contains the sugar ribose.

Front

What is the function of mRNA?

Back

mRNA (messenger RNA) carries the genetic code from DNA to the ribosome, where it serves as a template for protein synthesis.

Front

What is the process of Translation?

Back

Translation is the process where ribosomes read the sequence of mRNA and assemble amino acids into a polypeptide chain, forming a protein.

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.
