Protein Synthesis Recap

What are the three components of a nucleotide?

• sugar, hydrogen, nitrogen base
• sugar, oxygen, nitrogen base
• sugar, phosphate, nitrogen base
• sugar, phosphate, protein

In order for DNA instructions to move from the nucleus to the ribosomes in the cytoplasm of a cell, an RNA copy of a DNA strand must be made. This process, which takes place in the cell nucleus, is called

• translation
• mutation
• DNA replication
• transcription

How does RNA differ from DNA?

• RNA contains uracil and deoxyribose
• RNA contains ribose and thymine
• RNA contains uracil and ribose
• RNA contains adenine and ribose

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

• translation
• transcription
• transformation
• replication

When these bond together, they form a protein

• Amino Acids

• Peptide Bonds

• Ribose

• Nucleotides

These building blocks consist of a sugar, phosphate, and nitrogen base.

• Ribose

• Nucleotide

• Gene

• Protein

Which of the following is the complementary mRNA sequence to this DNA strand: AACTGAA

• UUGACUU

• TTGACTT

• AACTGAA

• AACUGAA

The genetic material of an organism is composed of

• lipids
• proteins
• deoxyribonucleic acids
• complex carbohydrates

The DNA sequence ATCAGCGCTGGC is part of a gene. how many amino acids are coded for by this message?

• 4
• 8
• 12
• 20

DNA sequence is ACAGTGC. How would this be coded on mRNA?

• TGTCACG
• UGUCACG
• GUGACAU
• CACUGUA
