Protein Synthesis

Question 1

Which describes the function of a peptide bond?'

Revolt · Accepted Answer

It connects amino acids.

Question 2

The diagram shows one step in the process of protein synthesis.Which step is shown?

Revolt · Accepted Answer

transcription

Question 3

Which nucleic acid moves the code for protein synthesis from the nucleus to the ribosomes?

Revolt · Accepted Answer

mRNA

Question 4

Which nucleic acid provides the master code for protein synthesis?

Revolt · Accepted Answer

DNA

Question 5

The study of Escherichia coli (E. coli) led researchers to new experimental designs for studying operons. Which experimental design did the scientists use?

Revolt · Accepted Answer

Read the genome sequence to determine the quantity and organization of operons.

Question 6

Which organelle is the location where mRNA is translated into a protein?

Revolt · Accepted Answer

ribosomes

Question 7

Which occurs during translation?

Revolt · Accepted Answer

mRNA codons are joined by tRNA anticodons to assemble amino acids to form a protein.

Question 8

During which process is mRNA converted into a sequence of amino acids for protein production?

Revolt · Accepted Answer

translation

Question 9

Only the proteins that the bacteria Escherichia coli (E. coli) needs are synthesized at any given time. For example, when lactose is available in the environment, E. coli will express the lac genes that allow it to break down lactose to obtain energy. When lactose is not present, these genes are not expressed.Which prevents the lac genes in the DNA of E. coli from being expressed most of the time?

Revolt · Accepted Answer

the lac repressor

Question 10

Which summary below correctly describes what occurs during transcription?

Revolt · Accepted Answer

A DNA template is used to create an mRNA strand.
