MolBio Lec Finals-Lesson 11: Transcription and Translation

A sequence of RNA is shown below:

5'-AUG GGG AAG UGU UGG-3'

Using the codon chart, what is the sequence of amino acids that are produced when this RNA is translated? Write the full names.

(Format: AA-AA-AA-AA-AA)

(a)  

The following DNA strand is used as a template for transcription:

3′-GGCACTCATTCAA-5'

Which of the following RNA strands will be produced?

(format: 5'- (a)   -3')

The following RNA strand was produced: 5′ CGA GUG AAU CGU UAA 3′ Which of the following DNA strands could have been the template for this RNA?

(a)  

A template strand of DNA in a gene reads:

3′-TCTCCAAGC-5′

Using the codon chart, what is the amino acid sequence produced after translation?

Write the full names.

(Format: AA-AA-AA)

(a)  

Genes are composed of segments of "extra," nonessential materials called exons.

• TRUE
• FALSE

Transcription takes place in the nucleus using the DNA in the nucleus as a template for the formation of proteins.

• TRUE
• FALSE

In the process of translation, the amino acids are arranged to form specific proteins because they are attached to:

• rRNA
• tRNA
• mRNA
• promoter
• none of the above

Which one of the following is not associated with translation?

• rRNA
• mRNA
• tRNA
• anticodon
• all are involved

Which one of the following is not associated with transcription?

• tRNA
• mRNA
• RNA polymerase
• DNA
• a promoter

Which enzyme is incorrectly matched to its function?

• RNA polymerase -- transcription

• aminoacyl-tRNA synthetase -- attaches an amino acid to a tRNA

• peptidyl transferase -- translation

• DNA ligase -- joins Okazaki fragments

• All of the choices are paired correctly.
