Protein Synthesis and the Genetic Code

A nucleotide does NOT contain

• sugar

• polymerase

• nitrogen base

• phosphate group

Which of the following nucleotides bonds with uracil?

• guanine

• cytosine

• thymine

• adenine

What breaks the H- bonds in order for DNA to separate during replication and protein synthesis?

• Enzyme (RNA polymerase)

• nitrogen bases

• the nucleus

• RNA

DNA is copied into 2 new strands of DNA during a process called:

• replication

• translation

• transcription

• transformation

In DNA replication, a section of DNA with bases ATTC will line up with bases:

• GAAC

• AUUG

• ATTC

• TAAG

One difference between DNA and RNA is that

• DNA= 1 strand

• DNA contains ribose sugar

• DNA has a double strand

• RNA is more complex

The process by which the genetic code of DNA is copied into a strand of mRNA is called:

• translation

• transformation

• transcription

• replication

A group of 3 letters representing an amino acid is called:

• nucleotide

• ribosome

• codon

• anticodon

If the triplet code in DNA is AGT, then the mRNA codon would be:

• TCA

• AGT

• TCU

• UCA

What happens during the process of translation?

• mRNA is made from DNA

• mRNA attaches o tRNA and makes protein

• copies of DNA molecules are made

• transfer RNA is made from mRNA
