Unit 2 Cell Biology Test Review

Front

What is the monomer or building block of DNA?

Back

Nucleotide

Front

What is the role of tRNA in protein synthesis?

Back

tRNA carries amino acids to the mRNA in the ribosome.

Front

In mitosis, how do the resulting cells compare genetically?

Back

The resulting cells are genetically identical (same).

Front

Where are codons located?

Back

Codons are located on mRNA.

Front

What is a hybrid in Animal Science?

Back

A hybrid is the sterile offspring of two different species.

Front

What are the three main components of a nucleotide?

Back

A nucleotide consists of a phosphate group, a sugar, and a nitrogenous base.

Front

What is the function of mRNA in protein synthesis?

Back

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

Front

What is the difference between DNA and RNA?

Back

DNA is double-stranded and contains thymine, while RNA is single-stranded and contains uracil.

Front

What is the process of transcription?

Back

Transcription is the process of copying a segment of DNA into mRNA.

Front

What is the role of ribosomes in protein synthesis?

Back

Ribosomes are the sites where translation occurs, synthesizing proteins from amino acids.
