Genetic Engineering

The first clone created in 1885 was a sea urchin.

Which technique can be used to make multiple copies of a gene? What are the basic steps in this procedure?

The miotic spindle moves the chromosomes around in the cell during prophase. The miotic spindle is formed by excess parts from the dismantled cytoskeleton.The spindle is initially setup outside the nucleus. p.s- im in ap biology so u can trust my answer :)

A ecosystem having significant biodiversity

Acquired. As it is caused by environmental and lifestyle facotrs such as smoking. In particular it is an example of chronic obstructive pulmonary disease (COPD).

its just a relatively non toxic detergent that helps wash the blot and remove any proteins that are non-specifically bound. some people follow up the TBST washes with a straight TBS wash to remove it, but it is not necessary. some people use TBST to dilute their Ab, too. Then again, some people use TBS, and add a little BSA (like .5 or .3%) to kind of keep blocking as they go along with the steps of the process. for that matter, you can just use a weak PBS with a 1% tween to dilute your Ab, too. It probably will not matter.

a karyotype

The Necleus is the brain of a cell. Nothing really occurs in the necleus, all the information to run the cell is found there, the neclues tells the cell what to do. I would say B. Translation only. I'm not sure through... maybe you should google "what occurs in the necleus" and use a different source.

Whenever Mendel performed a cross with pea plants, he carefully categorized and counted the many offspring. Every time Mendel repeated a particular cross, obtained similar results. For example, whenever Mendel crossed two plants that were hybrid for stem height (Tt), about three fourths of the resulting plants were tall and about one fourth were short. Mendel realized that the principles of probability could be used to explain the results of genetic crosses.

both near water and were once seperated to 2 different groups

what are some good points about exersize <-- you spelt exercise wrong and urmm ... it stops you from gettign obese and it can stop you from developing some kinds of cancer and it will stop you from going bald :O

an error in meiotic cell division

If the human population was reduced to a very small number of interbreeding individual then this small population, denied outbreeding, would have very little genetic variation. Humans, who went through a bottleneck event about 70,000 years ago, are considered a " small " species because they have little genetic variation in comparison to many other species.

Google cheetah to see how this concept works.

Type I diabetes that cannot be successfully treated with animal insulin.

Does alcohol addiction carry a strong genetic component? *

It is possible. Several studies have pointed out that alcoholism is more likely in someone who has family members that are alcoholics.

No you can't use expired Noni juice.

It is a hard application; Easy to find opinions and ethical issues but very hard to find concepts and processes.

Xeno- refers to Tissues, so concepts and processes include Tissue typing, Immuno-suppressants, Tissue engineering, and Genetic Modification.

A bottleneck event would decrease your population to a very small number and, consequently, your gene pool would contract, some alleles would be lost and genetic variability would decrease. Google Cheetahs.

Bioethics is the study of ethical issues related to DNA technology. Many scientists and nonscientists are involved in identifying and addressing any ethical, legal, and social issues that may arise as genetic engineering techniques continue to be developed.

to some extent it comes down to how much you eat and how regularly you eat it. eating lots of vitamin b and exrcising lots can improve your metabolism.

Granular leukocytes have multilobed nuclei that function against non specific invading agents in the body. Agranular leukocytes contain a single neuleus not sure about their function...

Bacteria have chromosomes that are not located within a nucleus (they don't have a nucleus). Chromosomes are normally found associated together in an area of the cell. Bacteria also have small circles of DNA called plasmids, these can sometimes be transferred between cells
