RNA and Protein Synthesis

Front

What is RNA polymerase?

Back

RNA polymerase is an enzyme in the nucleus that synthesizes mRNA from a DNA template during transcription.

Front

What are frameshift mutations?

Back

Frameshift mutations are genetic mutations caused by insertions or deletions of nucleotides that change the reading frame of the genetic code.

Front

What is the role of tRNA in protein synthesis?

Back

tRNA (transfer RNA) brings amino acids to the ribosome, where they are assembled into proteins according to the sequence of the mRNA.

Front

What is an anticodon?

Back

An anticodon is a sequence of three nucleotides in tRNA that pairs with a complementary codon in mRNA during protein synthesis.

Front

Which nitrogen base is not found in RNA?

Back

Thymine is not found in RNA; instead, RNA contains uracil.

Front

What is the function of mRNA?

Back

mRNA (messenger RNA) carries the genetic information from DNA in the nucleus to the ribosome in the cytoplasm for protein synthesis.

Front

What is the significance of codons?

Back

Codons are sequences of three nucleotides in mRNA that specify a particular amino acid during protein synthesis.

Front

How do mutations affect protein synthesis?

Back

Mutations can alter the amino acid sequence of a protein, potentially affecting its structure and function.

Front

What is transcription?

Back

Transcription is the process of copying a segment of DNA into RNA, specifically mRNA, in the nucleus.

Front

What is translation?

Back

Translation is the process by which ribosomes synthesize proteins using the information carried by mRNA.
