| Question | Answer |
|---|---|
| What is a a sequence of 3 dna bases that code for mRNA codon | Triplet |
| What is a sequence of 3 RNA bases that code for a specific amino acid? | Codon |
| What is a sequence of bases in tRNA that is complementary to a specific codon | Anticodon |
| What is the complementary RNA sequence of the following : TCCGATTCA, CCGGAATCGA, GACTGACT.? Note that they are 3 different sequence all of them are 10 marks.. | AGGCUAAGU, GGCCUUAGCU, CUGACUGA, |
| What is a gene? | A small section of DNA that contains the code for protein. |
| What is enzyme that binds DNA and help coil it up called? | Histone |
| What are the bond that join anticodons in rRNA called? | Peptide bonds |
| How many amino acids are they . | 20 different types |
| Where can you find DNA. | Nucleus |
| How do you form a protein. | Protein is formed when peptide bonds fold |
| What does RNA mean? | Ribonucleic acid |
| What does DNA mean? | Deoxyribose nucleic acid |
| What does mRNA mean and a what is it function? | messanger Ribonucleic acid and its function is to pass messages or information |
| What does tRNA mean and its function? | transfer Ribonucleic acid and its function is to transfer or transport |
| Which binds hold the structure of a DNA | Hydrogen bonds |
| Name two difference between DNA and RNA ? NB compare between two differences to attain marks(6) | DNA— double stranded. RNA— single stranded DNA — contains thymine. RNA — contain uracil DNA — dioxyribonucleic acid. rNA — ribonucleic acid Etc |
