Protein Synthesis

What is the function of ribosomes in a cell?

Back

Ribosomes are small organelles where proteins are assembled from amino acids based on the instructions carried by mRNA.

Front

Where does translation occur in the cell?

Back

Translation occurs in the ribosome.

Front

In RNA, which base pairs with adenine?

Back

In RNA, uracil pairs with adenine.

Front

What is a codon?

Back

A codon is a three-base sequence of mRNA that codes for a single amino acid.

Front

How many amino acids are coded by the nucleotide sequence ATG GGA ACT CCA?

Back

The sequence ATG GGA ACT CCA codes for 4 amino acids.

Front

What is the role of mRNA in protein synthesis?

Back

mRNA carries the genetic information from DNA to the ribosome, where it serves as a template for protein synthesis.

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.

Front

What is the process of transcription?

Back

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

Front

What are amino acids?

Back

Amino acids are the building blocks of proteins, and there are 20 different amino acids that combine in various sequences to form proteins.

Front

What is the start codon and its significance?

Back

The start codon is AUG, which signals the beginning of protein synthesis and codes for the amino acid methionine.
