Molecular Genetics Review

Front

What organelle is responsible for protein synthesis in cells?

Back

Ribosomes are the organelles responsible for protein synthesis.

Front

What type of transport requires energy in the form of ATP?

Back

Endocytosis is a type of transport that requires energy in the form of ATP.

Front

What are the building blocks of DNA?

Back

Nucleotides, which consist of a sugar, phosphate, and nitrogen base, are the building blocks of DNA.

Front

Which RNA takes the amino acid to the ribosome?

Back

tRNA (transfer RNA) takes the amino acid to the ribosome.

Front

What is the process called when mRNA is read and proteins are synthesized at the ribosome?

Back

The process is called Translation.

Front

What is the function of ribosomes in a cell?

Back

Ribosomes are responsible for synthesizing proteins by translating mRNA.

Front

What is the role of mRNA in protein synthesis?

Back

mRNA (messenger RNA) 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 into mRNA, while translation is the process of synthesizing proteins from mRNA.

Front

What is facilitated diffusion?

Back

Facilitated diffusion is a passive transport process that uses proteins to help move substances across the cell membrane.

Front

What is the structure of a nucleotide?

Back

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