From DNA to protein
Fill in the blanks using the words below to help you if needed
DNA is copied by a process called ______________ which occurs in the _____________ of
the cell. Only _____________ strand of DNA is copied, which contains the relevant gene.
The copied strand is called ___________________ . Trancription requires two enzymes_________ and _________. In mRNA, the base T is replaced by ______.
The pre-mRNA is then ________ to remove non-coding sequences called ________. This
requires a complex of enzymes called the ______________. The resulting mature mRNA
exits the nucleus via the _______ ______.
The copied strand leaves the nucleus and is decoded at a ____________ which are found in
the cytoplasm. This process is known as ____________. Each sequence of three bases,
known as a __________, codes for a particular _________________ which is brought to the
ribosome by _________________________ molecules. The _________on tRNA binds to the
complementary codon on mRNA to ensure the correct amino acid is bought over. The amino
acids are joined together using energy from ATP and an __________. When a
_________codon is reached, translation is terminated and the resulting amino acid chain
folds in to a _________.
