From there, the mRNA is brought to the ribosomes, some located on the rough endoplasmic reticulum and some free-floating, in order to be translated into proteins. Proteins are then packaged and transported to their respective locations for usage. The nucleolus is responsible for synthesizing and assembling ribosomal subunits. The nucleus houses DNA and is the site of transcription, but not translation. Mitochondria are essential for cellular respiration and ATP synthesis.
Ap Biology – Modern Genetics
What Is AP Biology? Course Overview
In a RNA nucleotide the organic bases can be uracil, adenine, guanine or cytosine. Where as in a DNA nucleotide there can be thymine, adenine, guanine or cytosine. It carries the genetic information which is what gives a living thing specific trait such ad brown hair or. Part A Done on the attached paper. Answers to questions 1 How were you able to derive amino acids from your DNA sequence? First of all, from the sense strand given in the question, I derived the antisense strand for it.

Genetic drift, defined as the process in which chance events cause unpredictable fluctuations in allele frequencies from one generation to the next, can increase or decrease variability within particularly small populations.
In: Science. Cells are equipped with controls that govern gene expression; that is, which gene products appear, when, and what amounts. Cells of complex organisms inherit the same genes, yet most become specialized in composition, structure, and function.
