Fill the blank spaces to complete the text.

The first stage of DNA replication is of DNA, which is aided by the enzyme . Next, the two strands are , thanks to an enzyme called DNA , which breaks the bonds holding the bases together. Then, new strands of DNA are synthesised by an enzyme called . In this stage, free nucleotides are joined to their complementary bases and each other by forming h bonds and p bonds. They're added in the ' to ' direction.

Which of the following statements is true about mutations?

Select one of the following:

Mutations arise when there's an error when matching complementary bases.
Mutations occur when there's an evolutionary need for a new adaptation.
Mutations are always harmful to the organism.
Mutations can always be seen in the phenotype of the organism.

The sequence of nucleotide bases in DNA dictates the primary structure of proteins.

Select one of the following:

True
False

Select from the dropdown lists to complete the text.

DNA is read three bases at a time, these are called ( triplets, amino acids, mRNA, trios ).
DNA is found in nearly all living organisms, so it is ( universal, degenerate, non-overlapping, unique ).
There are often several ways of coding for one amino acid, so DNA is ( degenerate, overlapping, universal, stored in nucleosomes ).
DNA bases are read one after the other, so it is ( non-overlapping, degenerate, called a codon, universal ).

is the process of RNA being created according to a region of DNA (catalysed by ), whereas is the process of joining amino acids together according to the sequence of bases on a strand of RNA.

Select from the dropdown lists to complete the text.

Three bases on an mRNA molecule require a specific ( amino acid, metabolism, transcription, translation ). The ( anticodon, triplet, amino acid binding site, loop ) on a tRNA molecule is matched to a ( triplet, amino acid binding site, tRNA molecule, base ) on an mRNA molecule. Also, tRNA molecules with a specific ( anticodon, transcription, translation, arrangement ) will have a specific ( amino acid attachment site, triplet, codon, hydrogen bonding arrangement ), and therefore binds a specific ( amino acid, mRNA molecule, ribosome, 80s ribosome sub-segment ).
