Intro to Gene Technology

The difference between DNA and RNA

• DNA is double-stranded with deoxyribose; RNA is single-stranded with ribose.
• DNA is found in the cytoplasm; RNA is found in the nucleus.
• DNA is single-stranded with ribose; RNA is double-stranded with deoxyribose.
• DNA contains uracil; RNA contains thymine.

DNA replication during

• G1 of Interphase

• S-phase of Interphase

• G2 of Interphase

• Mitosis

Enzyme that very important during DNA replication

• RNA polymerase
• Helicase
• Ligase
• DNA polymerase

What is gene

• A gene is a unit of heredity in living organisms, made up of DNA.
• A gene is a molecule that carries oxygen in the blood.
• A gene is a type of cell organelle.
• A gene is a type of protein found in cells.

The difference between DNA and RNA

• DNA is found in the cytoplasm; RNA is found in the nucleus.

The process of protein synthesis includes transcription and translation. The correct statement about transcription is ...

• Transcription only occurs in prokaryotic cells and does not involve DNA.
• Transcription is the process of translating mRNA into amino acids.
• Transcription occurs in the cytoplasm and involves the synthesis of proteins from mRNA.
• Transcription occurs in the nucleus and involves the synthesis of mRNA from a DNA template.

Enzyme that is very important during transcription?

• DNA polymerase
• Ligase

• Helicase
• RNA polymerase

What happen during RNA splicing

• RNA splicing adds introns to pre-mRNA.
• RNA splicing converts DNA into RNA.
• RNA splicing synthesizes proteins from amino acids.
• RNA splicing removes introns and joins exons in pre-mRNA.

The correct statement about translation during protein synthesis

• Translation occurs in the ribosome, where mRNA is decoded into a protein.
• Translation is the process of converting amino acids into carbohydrates.
• Translation happens in the cytoplasm, where proteins are synthesized from lipids.
• Translation occurs in the nucleus, where DNA is decoded into RNA.

The correct statement about gene, protein, and phenotype

• Genes influence phenotypes, which determine proteins.
• Phenotypes determine genes, which influence proteins.
• Genes determine proteins, which influence phenotypes.
• Proteins determine genes, which influence phenotypes.
