Unit 4 Review

Front

Which type of plant did Gregor Mendel use for his genetic experiments?

Back

Gregor Mendel used Pea Plants for his genetic experiments, which allowed him to study inheritance patterns.

Front

What mutation has occurred when T-G-A-C-A changes to T-G-A-G-A?

Back

The mutation is a Substitution, where one base is replaced by another.

Front

What is the correct amino acid sequence for the mRNA code AUGCCAGUAUGA?

Back

The correct amino acid sequence is Met-Pro-Val.

Front

What are the possible flower colors in the offspring when crossing a homozygous purple flower plant with a homozygous white flower plant?

Back

All offspring will have purple flowers.

Front

What is the term for the codon that signals the start of translation?

Front

What is the role of tRNA in protein synthesis?

Back

tRNA transfers amino acids to the ribosome during protein synthesis.

Front

What is a genotype?

Back

A genotype is the genetic makeup of an organism, represented by the alleles it possesses.

Front

What is the difference between dominant and recessive alleles?

Back

Dominant alleles express their trait even when only one copy is present, while recessive alleles require two copies to express their trait.

Front

What is a phenotype?

Back

A phenotype is the observable physical or biochemical characteristics of an organism, determined by its genotype.
