Front

What are amino acids?

Back

Amino acids are organic compounds that combine to form proteins, and they are not carried to ribosomes by messenger RNA.

Front

What is the role of messenger RNA (mRNA) in protein synthesis?

Back

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

Front

What is the mRNA sequence for the DNA sequence TACTTACCGAGCTAGACT?

Back

AUGAAUGGCUCGAUCUGA

Front

What is a Punnett square used for?

Back

A Punnett square is a diagram used to predict the genetic makeup of offspring from a genetic cross.

Front

In a cross between Aa x Aa, how many offspring will have the genotype AA?

Back

1

Front

What does F1 generation refer to in genetics?

Back

The F1 generation refers to the first generation of offspring produced from a cross of two parental (P) organisms.

Front

What is a heterozygous genotype?

Back

A heterozygous genotype has two different alleles for a trait, such as Bb.

Front

What is a homozygous genotype?

Back

A homozygous genotype has two identical alleles for a trait, such as AA or ee.

Front

What is the difference between genotype and phenotype?

Back

Genotype refers to the genetic makeup of an organism, while phenotype refers to the observable traits.

Front

What is the purpose of transcription in protein synthesis?

Back

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