What is the purpose of transcription in protein synthesis?

To fold proteins into their functional shapes

What is the role of mRNA in protein synthesis?

It takes the code from DNA in the nucleus to the ribosomes.

It replicates DNA inside the nucleus.

It carries amino acids to the ribosomes.

It converts ribosomes into proteins.

During translation, what is the sequence that leads to the formation of a protein?

Codon → amino acid → polypeptide chain → protein

Codon → tRNA → protein → polypeptide chain

mRNA → amino acid → polypeptide chain → protein

tRNA → codon → amino acid → protein

What is the purpose of using gel electrophoresis in biotechnology?

To increase the size of DNA fragments

To change the properties of DNA

What do restriction enzymes do in the process of gel electrophoresis?

They join different DNA fragments

They make DNA visible under UV light

What is a major ethical question in biotechnology?

Is it ethical to use antibiotics?

Is it ethical to consume genetically modified foods?

What is the purpose of meiosis in sexual reproduction?

To duplicate genetic information

To increase the number of chromosomes

What is the genetic characteristic of the new cells formed by meiosis?

They have different genetic information from each other

They have identical genetic information to the parent cell

They have double the genetic information of the parent cell

They have the same genetic information as each other

What is a similarity between mitosis and meiosis?

Both start with a single parent cell

Both produce the same number of daughter cells

Both result in increased genetic variation

Both have the same number of stages

What is a characteristic of offspring produced by sexual reproduction?

Genetically identical to the parent

What is a disadvantage of asexual reproduction?

Allows for no genetic variation

Produces genetically different offspring

According to Mendelian Genetics, what does the Law of Segregation state?

Organisms get 2 copies of genes, one from each parent

Each parent is responsible for passing down 2 alleles

Traits are inherited together with other traits

Only dominant alleles are passed down to offspring

What does the Law of Independent Assortment suggest?

Each trait is inherited independently of other traits

Each trait is inherited based on the alleles of the previous trait

Traits are inherited together and cannot be separated

Only one trait can be inherited at a time

What does it mean if an individual is considered a carrier for a recessive genetic disorder?

They have two different alleles and the dominant allele masks the disorder

They have two dominant alleles and express the disorder

They have two recessive alleles and express the disorder

They have two different alleles and can pass the disorder to offspring

What is the purpose of the diagram shown in the image?

To predict the outcome of a genetic cross

To demonstrate a chemical reaction

What is an example of codominance in genetics?

A red cow crossed with a white cow produces spotted offspring.

A red flower crossed with a white flower produces pink flowers.

A tall plant crossed with a short plant produces medium height plants.

A brown mouse crossed with a white mouse produces all brown offspring.

When a base(s) is added to the DNA sequence

When a base(s) is removed from the DNA sequence

When one base changes and has the potential to change one amino acid

When the entire DNA sequence is replaced

What is a frameshift mutation?

A mutation that does not change the amino acid sequence

A mutation that occurs when a base(s) is added or removed from the DNA sequence

A mutation that occurs when the DNA sequence is unchanged

A mutation that occurs when one base is substituted for another without any addition or deletion
