Protein Synthesis, Meiosis, and Genetics Review

Why does DNA replicate?

• To create variations in genetic material.
• To repair damaged DNA strands.
• To provide identical copies of genetic material for cell division and new cells.

• To produce energy for cellular processes.

What makes a sex cell go back to a diploid number?

• Meiosis increases the diploid number.
• Fertilization of gametes restores the diploid number.
• Asexual reproduction maintains the diploid state.
• Cell division without fertilization doubles the chromosome count.

What carries genetic information from the nucleus to the ribosomes?

• mRNA
• DNA
• tRNA
• ribosomal RNA

What is transcription?

• Transcription is the process of replicating DNA into DNA.
• Transcription is the process of translating RNA into DNA.

• Transcription is the process of synthesizing proteins from amino acids.
• Transcription is the process of copying DNA into mRNA.
