Unit 5: DNA, RNA, Protein Synthesis Review

Front

Where does transcription take place in a eukaryotic cell?

Back

Transcription takes place in the nucleus.

Front

What is the process of converting DNA to mRNA called?

Back

Transcription.

Front

How is the DNA sequence GCTATA transcribed to mRNA?

Back

The mRNA sequence is CGAUAU.

Front

What is homeostasis?

Back

Homeostasis is the process by which living organisms maintain a stable internal environment.

Front

In which organelle is DNA usually found?

Back

DNA is usually found in the nucleus.

Front

What is a codon?

Back

A codon is a sequence of three nucleotides that corresponds to a specific amino acid or stop signal during protein synthesis.

Front

How many codons are there in the genetic code?

Back

There are 64 codons in the genetic code.

Front

What is the role of mRNA in protein synthesis?

Back

mRNA carries the genetic information from DNA to the ribosome, where proteins are synthesized.

Front

What is the difference between DNA and RNA?

Back

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

Front

What are the three main types of RNA involved in protein synthesis?

Back

The three main types of RNA are messenger RNA (mRNA), transfer RNA (tRNA), and ribosomal RNA (rRNA).
