Shared Unit 2.4 DNA Review

Front

What is a Codon?

Back

A codon is a sequence of 3 base pairs in DNA or RNA that corresponds to a specific amino acid or stop signal during protein synthesis.

Front

Where does Translation occur?

Back

Translation occurs in the ribosomes, which are the cellular structures responsible for synthesizing proteins.

Front

What is the difference between genotypic change and phenotypic change?

Back

Genotypic change refers to alterations in the genetic makeup (DNA sequence), while phenotypic change refers to observable traits or characteristics resulting from the genotype.

Front

What is the role of Ribosomes in protein synthesis?

Back

Ribosomes are the sites where translation occurs, facilitating the assembly of amino acids into proteins based on the sequence of codons in mRNA.

Front

What is Cloning in genetics?

Back

Cloning is the process of creating a genetically identical copy of an organism or cell, which decreases genetic variation.

Front

What is Recombination in genetics?

Back

Recombination is the process by which genetic material is rearranged during meiosis, leading to increased genetic variation.

Front

What base pairs with Cytosine (C) in RNA?

Back

In RNA, Cytosine (C) pairs with Guanine (G).

Front

What is the significance of the Genetic Code?

Back

The genetic code is a set of rules that defines how the sequence of nucleotides in DNA or RNA is translated into the amino acid sequence of proteins.

Front

What is a Mutation?

Back

A mutation is a change in the DNA sequence that can lead to changes in the structure and function of proteins.

Front

What is the function of mRNA?

Back

mRNA (messenger RNA) carries the genetic information from DNA to the ribosomes, where it serves as a template for protein synthesis.
