Front

What is RNA splicing?

Back

RNA splicing is a process that removes introns from a pre-mRNA transcript and joins together the remaining exons, allowing for the production of a mature mRNA molecule that can be translated into a protein.

Front

What are glycoproteins?

Back

Glycoproteins are molecules that consist of a protein and a carbohydrate (sugar) component. They often play key roles in cell recognition and signaling.

Front

What is gene regulation in eukaryotes?

Back

Gene regulation in eukaryotes involves mechanisms that control the expression of genes at various stages, including transcriptional regulation, post-transcriptional regulation, and epigenetic modifications.

Front

What is somatic cell nuclear transfer?

Back

Somatic cell nuclear transfer is a cloning technique where the nucleus of a somatic cell is transferred into an enucleated egg cell, leading to the development of an organism genetically identical to the donor.

Front

What are tumor-suppressor genes?

Back

Tumor-suppressor genes are genes that help prevent uncontrolled cell growth and division, thereby suppressing tumor formation.

Front

What is transcriptional regulation?

Back

Transcriptional regulation is the control of the amount and timing of mRNA production from a gene, influencing gene expression.

Front

What is post-transcriptional regulation?

Back

Post-transcriptional regulation refers to the control of gene expression at the RNA level, including processes like RNA splicing, editing, and degradation.

Front

What are epigenetic modifications?

Back

Epigenetic modifications are heritable changes in gene expression that do not involve changes to the underlying DNA sequence, such as DNA methylation and histone modification.

Front

What is the role of spike-like projections on viruses?

Back

Spike-like projections on viruses, often made of glycoproteins, are crucial for the virus's ability to attach to and enter host cells.

Front

What is the significance of Dolly the sheep?

Back

Dolly the sheep was the first mammal to be cloned from an adult somatic cell, demonstrating that specialized cells could be reprogrammed to develop into a whole organism.
