2025 Semester 1 Biology Test Review

Front

What is a genotype?

Back

The allele combinations of an organism that determine its traits.

Front

What is a phenotype?

Back

The observable expression of a trait in an organism.

Front

Where does the translation of mRNA into amino acids occur?

Back

In the Ribosome.

Front

What is a nucleotide?

Back

A monomer consisting of sugar, phosphate, and a nitrogen base.

Front

What does the genotype 2 Yy: 2 yy: 0 YY represent?

Back

It represents the allele combinations from a genetic cross.

Front

What is the role of ribosomes in a cell?

Back

Ribosomes are the sites where mRNA is translated into proteins.

Front

Define allele.

Back

An allele is a variant form of a gene that can produce different traits.

Front

What is the difference between genotype and phenotype?

Back

Genotype refers to the genetic makeup, while phenotype refers to the physical expression of traits.

Front

What is the function of mRNA?

Back

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

Front

What are the components of a nucleotide?

Back

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