The mRNA bases are grouped into sets of three, called codons. Each codon has a complementary set of bases, called an anticodon. Anticodons are a part of transfer RNA (tRNA) molecules. Attached to each tRNA molecule is an amino acid -- in this case, the amino acid is methionine (met).You've matched the first codon in this mRNA molecule, AUG, with its complement, UAC.Description: Ribosome moves to the right.n this case, though, you need to find the complement of each codon. Drag the appropriate tRNA from the bottom of the screen to the leftmost codon of the mRNA. What Happened Window: A ribosome has attached itself to the mRNA.Ribosomes are the cell's structures for building proteins.
Mallards lay between 8-12 eggs and muscovies lay between 12-18 eggs. The egg laying process lasts for an equal number of days (it takes 12 days to lay 12 eggs).Once egg laying is complete, she will leave the male (who will wait at the water for her) and she will begin incubation on the nest fulltime.allards lay between 8-12 eggs and muscovies lay between 12-18 eggs.

This is called a 'brood patch'. Different birds sit on their eggs for different lengths of time. Bigger birds lay bigger eggs which take longer to hatch. Blue tits incubate their eggs for two weeks but swans sit on theirs for nearly six weeks!Most birds lay one egg a day until the eggs are all laid. Some birds lay up to 15 eggs but others lay only one.But the parent birds do not start to incubate the eggs until they are all laid.lue tits incubate their eggs for two weeks but swans sit on theirs for nearly six weeks!
