What is the role of RNA polymerase in transcription?

Back

RNA polymerase is the enzyme responsible for synthesizing RNA from a DNA template during the process of transcription.

Front

How are DNA and RNA similar?

Back

Both DNA and RNA contain the nitrogenous bases cytosine (C) and guanine (G).

Front

How many amino acids are coded by the DNA sequence ATCAGCGCTGGC?

Back

The DNA sequence ATCAGCGCTGGC codes for 4 amino acids.

Front

Where does translation occur in the cell?

Back

Translation occurs at the ribosome in the cytoplasm.

Front

What is transcription?

Back

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

Front

What are the main components of RNA?

Back

RNA is composed of ribose sugar, phosphate groups, and nitrogenous bases (adenine, uracil, cytosine, and guanine).

Front

What is the function of ribosomes in protein synthesis?

Back

Ribosomes are the cellular structures where translation occurs, synthesizing proteins by linking amino acids together.

Front

What is the difference between DNA and RNA?

Back

DNA is double-stranded and contains thymine (T), while RNA is single-stranded and contains uracil (U) instead of thymine.

Front

What is a codon?

Back

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

Front

What is the significance of the start codon?

Back

The start codon (AUG) signals the beginning of translation and codes for the amino acid methionine.
