Biology Semester 1 Review

Front

What are the building blocks of proteins?

Back

Amino acids are the building blocks of proteins.

Front

Where is the site of translation?

Back

The site of translation is the ribosomes.

Front

What amino acid sequence is encoded in the partial DNA segment 3′ TCATGCATG 5′?

Back

The amino acid sequence encoded is Serine – Threonine – Tyrosine.

Front

What does semi-conservative DNA replication mean?

Back

Semi-conservative DNA replication means that each new DNA molecule is composed of one new strand and one original strand of DNA.

Front

What is the equation for cellular respiration?

Back

The equation for cellular respiration is 6O2 + C6H12O6 = 6CO2 + 6H2O + Energy.

Front

What is the function of ribosomes in a cell?

Back

Ribosomes are responsible for protein synthesis.

Front

Define transcription in the context of protein synthesis.

Back

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

Front

What role do amino acids play in the body?

Back

Amino acids are essential for building proteins, which are crucial for various bodily functions.

Front

What is the difference between DNA and RNA?

Back

DNA is double-stranded and contains deoxyribose sugar, while RNA is single-stranded and contains ribose sugar.

Front

What is a codon?

Back

A codon is a sequence of three nucleotides in mRNA that corresponds to a specific amino acid.
