Biology: Chap. 11

Flashcards covering essential vocabulary terms related to molecular biology concepts discussed in the lecture notes.

Post Transcriptional Modification

Modification of RNA after it is made.

Post Translational Modification

Modification of a protein after it is made.

Control of Transcription

Mode of control that is best characterized and can be performed in vitro.

Histones

Proteins associated with DNA that help in winding and packaging.

Heterochromatin

Tightly wrapped DNA with less transcription.

Euchromatin

Less tightly wound DNA with more transcription.

DNA Methylation

Addition of methyl groups to cytosine nucleotides.

Epigenetics

Inherited change in the methylation patterns of an individual's somatic cells.

Three differences of DNA and RNA

RNA has a U instead of a T (Uracil instead of Thymine)

mRNA

A transcript of a protein coding gene.

Small Nuclear RNA

Small RNAs that exist inside the nucleus and the spliceosome is made up of.

Three to Five

Direction that DNA polymerase can only move.

Silent Mutation

There is a change to the coding sequence of DNA, however there is no change to the overall structure.

Coding Sequence

A section of DNA that changes from a g to an a.

Gamete

Cells that are associated with Mitosis and Meiosis

Allele

Cells that are associated with Mitosis and Meiosis

Poly One

DNA Poly one replaces the RNA.

Clinical Career Memorization

It is important to memorize processes of DNA replication.
