CHAPTER V: TRANSCRIPTION AND TRANSLATION (MODULE) part 1

Question 1

The genetic code is written in ________________using as _________ the ribonucleotide bases that compose mRNA molecules.

Answer 1

Linear form
“letters”

Question 2

The ______________ is derived from the _____________ nucleotide bases in DNA.

Answer 2

ribonucleotide sequence
complementary

Question 3

Each “word” within the mRNA consists of three ribonucleotide letters, thus referred to as a ____________

Answer 3

triplet code

Question 4

The code is ______________—each triplet specifies only a single amino acid.

Answer 4

unambiguous

Question 5

The code is ____________ meaning that a given amino acid can be specified by more than one triplet codon. This is the case for 18 of the 20 amino acids.

Answer 5

degenerate,

Question 6

No internal ___________ (analogous, for example, to a comma) is used in the code. Thus, the code is said to be _________. Once translation of mRNA begins, the codons are read one after the other with ___________between them (until a stop signal is reached).

Answer 6

punctuation
commaless
no breaks

Question 7

The code is ___________. After translation commences, any single ribonucleotide within the mRNA is part of only
one triplet.

Answer 7

nonoverlapping

Question 8

The sequence of codons in a gene is ____________, with the sequence of amino acids making up the encoded protein.

Answer 8

colinear

Question 9

The code is nearly _________. With only minor exceptions, a single coding dictionary is used by almost all viruses, prokaryotes, archaea, and eukaryotes.

Answer 9

universal
