Bahan manakah dihasilkan oleh fotosintesis?

1. AAsid laktik dan ATP
2. BKarbon dioksida dan air
3. CProtein dan nitrogen
4. DGlukosa dan oksigen

Apakah tugas utama aparatus Golgi?

1. AMenyalin DNA sebelum sel membahagi
2. BMengubah suai dan membungkus protein
3. CMengawal gen yang dihidupkan
4. DMenghasilkan ATP melalui respirasi sel

What is the SI base unit of mass?

Why does PCR use a DNA polymerase taken from bacteria that live in hot springs?

1. AIt survives the high temperatures used to separate the strands
2. BIt works only in the dark, like the bacteria it comes from
3. CIt copies RNA as well as DNA
4. DIt makes the DNA strands stick together

Why are G–C base pairs held together more strongly than A–T pairs?

1. AA–T pairs are found only in RNA
2. BG–C pairs are joined by strong covalent bonds instead of hydrogen bonds
3. CG–C pairs form three hydrogen bonds, and A–T pairs form two
4. DG and C are both purines, so they fit more tightly

What happens in the Calvin cycle of photosynthesis?

1. ALight is absorbed by chlorophyll
2. BGlucose is broken down to release energy
3. CCO₂ is built into sugar using ATP and NADPH
4. DWater is split to release oxygen

How does the CRISPR-Cas9 gene-editing system find the right place to cut DNA?

1. AIt binds only to the start codon of every gene
2. BA guide RNA pairs with the matching DNA sequence
3. CIt reads the amino acid sequence of the protein
4. DThe Cas9 protein cuts DNA at random sites

A single-celled organism has a nucleus, no cell wall and swims using cilia. In which group is it best placed?

1. AProtists
2. BFungi
3. CPlants
4. DBacteria
