DNA, Genes, and Inheritance Review

Front

What is a Dihybrid Cross?

Back

A genetic cross that involves two different traits, predicting the genetic probability of offspring using two different sets of alleles on two different chromosomes.

Front

What is the error in terminology regarding sister chromatids during mitosis?

Back

Referring to them as chromosomes before cell division.

Front

What is the correct sequence of genetic information flow?

Back

DNA -> RNA -> Protein.

Front

What is the role of tRNA during translation?

Back

tRNA pairs with mRNA codons through anticodon pairing, bringing the appropriate amino acids for protein synthesis.

Front

What does the term 'genome' refer to?

Back

The sum total of all genetic information in a cell, including mitochondrial and chloroplast DNA.

Front

Define Co-Dominance.

Back

A genetic scenario where both alleles in a heterozygote are fully expressed, resulting in offspring with a phenotype that is neither dominant nor recessive.

Front

What is Incomplete Dominance?

Back

A genetic situation where the phenotype of heterozygotes is intermediate between the phenotypes of the two homozygotes.

Front

What is a Monohybrid Cross?

Back

A genetic cross that involves one trait, predicting the genetic probability of offspring using one set of alleles.

Front

What is the function of mRNA?

Back

mRNA carries the genetic information from DNA to the ribosome, where proteins are synthesized.

Front

What is the role of the ribosome in protein synthesis?

Back

Ribosomes facilitate the translation of mRNA into a polypeptide chain by linking amino acids together.
