Front

What is the process of protein synthesis?

Back

The process of protein synthesis involves the following steps: DNA -> mRNA -> tRNA -> protein.

Front

Which amino acid is represented by the RNA codon UUA?

Back

Leucine.

Front

What is the base sequence of the original DNA segment if the mRNA sequence is UGU CAA ACU CGA?

Back

ACA GTT TGA GCT.

Front

What does a gene mutation cause in terms of cell division?

Back

A gene mutation can cause abnormal mitotic division.

Front

Which organism receives the least amount of energy from the producer?

Back

Owl.

Front

What is mRNA and its role in protein synthesis?

Back

mRNA (messenger RNA) is a type of RNA that carries the genetic information from DNA to the ribosome, where proteins are synthesized.

Front

Define transcription in the context of protein synthesis.

Back

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

Front

What is the role of tRNA in protein synthesis?

Back

tRNA (transfer RNA) brings amino acids to the ribosome during translation, matching them to the mRNA codons.

Front

Explain the difference between DNA and RNA.

Back

DNA (deoxyribonucleic acid) is double-stranded and contains the sugar deoxyribose, while RNA (ribonucleic acid) is single-stranded and contains the sugar ribose.

Front

What is a codon?

Back

A codon is a sequence of three nucleotides in mRNA that corresponds to a specific amino acid.
