Review Part 3 Biology Fall 2024 Semester Exam

Front

What determines the code of a DNA molecule?

Back

The order (sequence) of the nitrogen bases.

Front

What is the template for the production of RNA within a cell?

Back

DNA.

Front

What base does RNA have instead of thymine?

Back

Uracil.

Front

What is the process called when the genetic code of DNA is copied into RNA?

Back

Transcription.

Front

How does RNA differ from DNA?

Back

RNA is single-stranded, contains ribose sugar, and uses uracil instead of thymine.

Front

What are the building blocks of DNA?

Back

Nucleotides.

Front

What are the four nitrogen bases found in DNA?

Back

Adenine, thymine, cytosine, and guanine.

Front

What is the role of ribosomes in protein synthesis?

Back

Ribosomes are the sites where proteins are synthesized from amino acids.

Front

What is the function of messenger RNA (mRNA)?

Back

mRNA carries the genetic information from DNA to the ribosome for protein synthesis.

Front

What is the difference between transcription and translation?

Back

Transcription is the process of copying DNA to RNA, while translation is the process of synthesizing proteins from RNA.
