BIOL 191 FA 2024 Final exam review

Front

What does RNA polymerase transcribe during transcription?

Back

The Template Strand.

Front

What is the purpose of alternative splicing?

Back

The production of multiple protein variants from a single gene.

Front

What percentage of the human genome codes for proteins?

Back

1%.

Front

What are FADH and NADH examples of?

Back

Electron carriers.

Front

What type of transport does a channel protein represent?

Back

Passive Transport.

Front

Define transcription in the context of molecular biology.

Back

The process of synthesizing RNA from a DNA template.

Front

What is the role of introns in gene expression?

Back

Introns are non-coding sequences that are removed during RNA processing.

Front

What is the difference between the coding strand and the template strand of DNA?

Back

The coding strand has the same sequence as the mRNA, while the template strand is complementary to the mRNA.

Front

What is the significance of the 1% coding region in the human genome?

Back

It highlights that most of the genome is non-coding, which may have regulatory or unknown functions.

Front

What is passive transport?

Back

The movement of substances across a cell membrane without the use of energy.
