Describe how biogeographical studies, esp. of islands and continents, explain species similarities and differences

Biology
1 answer:
Elan Coil [88]3 years ago
5 0
Biogeographical studies use information for various fields, such as evolutionary biology, geography, geology, and climate science to determine how organisms evolved through time and how the moving of tectonic plates resulting in forming continents, mountain ranges and islands has affected their distribution.
Studies in this field explain how organisms that now live on different continents are very closely related and how the flora and fauna of islands are connected to one of the closest continents etc.

Describe how restriction enzymes and ligase enzymes are used to make the plasmids that are introduced to bacteria cells during t
balandron [24]

Answer:

DNA restriction enzymes cut the DNA molecule, while DNA ligases join the resulting DNA fragments

Explanation:

Transformation is a naturally occurring process by which bacteria incorporate exogenous genetic material from their surrounding environment. This process (transformation) is used for DNA cloning via plasmid vectors. In DNA cloning, transformation occurs after restriction enzymes cut the DNA at specific sequences named palindromic sequences (i.e, sequences that can be read the same in opposite direction). Restriction enzymes can generate sticky-ends, where enzymes make staggered cuts in the two strands (e.g., <em>BamH</em>), or blunt ends, where the resulting strands are of the same length (e.g., <em>HaeIII</em>). In general, sticky-end enzymes are more useful because they generate a 3' overhang in one molecule and a complementary 5' overhang in the other, increasing the yield and specificity of ligation. During ligation, a DNA ligase is used to join both DNA strands by forming phosphodiester bonds in the plasmid. Following transformation, bacteria can be selected on antibiotic plates.

"the term normally applied when two genes fail to assort independently is ________."
IgorC [24]
LINKAGE

Independent assortment refers to the allele segregation of two different genes. They are expected to be segregated from each other independently.This is not seen in monohybrids, they are usually heterozygous for an allelic pair only. Link genes cannot assort independently. These are inherited together during meiosis phase of sexual reproduction. Usually genes that are close together will tend to stick together resulting into inheritance of genes as pairs.
