wBS #11: Meiosis, Protein Synthesis, & Mutations

Front

The process to go from DNA to mRNA is _______

Back

transcription

Front

A mutation is a _______________ in the nucleotide base sequence of a gene.

Back

change

Front

Crossing over helps promote 

Back

genetic variation

Front

What type of mutation is shown in this picture?

Back

Insertion

Front

The main function of tRNA is to...

Back

bring amino acids from the cytoplasm to the ribosomes

Front

What is the role of mRNA in protein synthesis?

Back

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

Front

Define meiosis.

Back

Meiosis is a type of cell division that reduces the chromosome number by half, resulting in four haploid cells.

Front

What is the significance of genetic variation?

Back

Genetic variation is important for evolution and adaptation, allowing populations to survive changing environments.

Front

What is a substitution mutation?

Back

A substitution mutation is a type of mutation where one nucleotide is replaced by another in the DNA sequence.

Front

What is the role of ribosomes in protein synthesis?

Back

Ribosomes are the cellular structures where proteins are synthesized by translating mRNA.
