Introduction

Reading research papers (primary articles) is partly a matter of experience and skill, and partly learning the specific vocabulary of a field. First of all, don’t panic! If you approach a primary article step by step, even an impossible looking paper can be understood.

A directional (forced) clonning is planned using the restriction enzymes Pst1 and Sph1 to generate incompatible termini in the vector pUC18. Note that enzymes have different optimum buffer requirements and must be digested sequentially rather than simultaneously. The plasmid is first digested with Sph1, purified on a column, eluted and resuspended in Pst1 buffer and digested with Ps

A vector was prepared by a double restriction digest (EcoR1 + BamH1) to generate different ends for zero background colonies.

What result would be obtained when the transformation plates were examined? 4marks... i h

Simulation of Genetic Drift Animation
The inheritance of genes in sexual reproduction has a major chance component. During meiosis homologous chromosomes separate and migrate to different poles. The haploid daughter cells each have one allele for each gene, but which allele they have is random. Essentially meiosis is like flipping thousands of coins and getting either a head (one allele) or a tail (the other allele) for

What is meant by gene expression?

In a multicellular organism, usually every cell contains the complete genome. All genes are present in every nucleus. However, in any given cell, only some of the genes are actually producing mRNA. Many of the genes are inactive and never do anything. Other genes only produce mRNA at certain points in the life of a cell or in resp

How do hormones work?

Hormones influence the growth and develop of organisms. For example hormones determine whether individuals become male or female. Many hormones are steroids. Steroids are a class of lipids. All steroids share a carbon skeleton composed of four fused rings. Hormones are compounds used for long distance signaling in both plants and animals. In a
