Answer:
Human males much more likely than human females to inherit the recessive condition hemophilia because it follows X-linked recessive pattern.
Explanation:
Actually hemophilia is an X-linked recessive disorder i-e the defective genes are located on the X chromosome (sex chromosome) and are transmitted through it. As males have only one X chromosome (inherited from mother), one altered copy of the gene in every cell cause this disease.On the other hand females have 2 X chromosomes thus this disease is rare in females.
Answer:
The most appropriate way of sharing the results is to publish in a scientific journal for peer review. So the answer is 'B'.
Explanation:
In order to validate your results in the scientific community, it is best to publish in a <em>scientific journal</em> and get it peer reviewed. When the article is peer reviewed, other scientists of <em>higher caliber</em> verify your experiment and results and then give their verdict to the outside world.
Newspapers sometimes also <em>publish rumors</em>. So there is no guarantee what gets published is true. the students are still learning and cannot appreciate the full extent of your work.
The stages of DNA bases in a molecule can determine the order of amino acids in protein molecules. Groups of three bases called triplets represent different amino acids. This is the basis of the genetic code . A sequence of bases (genetic information) on DNA that codes for a protein is called a gene
Answer:
Melanocytes are located in the stratum basale.
Explanation:
Melanin is the pigment responsible for skin color. It is produced by melanocytes located in the base of the epidermis.
The epidermis is made up of five cell layers, which have different functions: Stratum basale, stratum spinosum, stratum granulosum, stratum lucidum, and stratum corneum.
Stratum basale is the innermost germinative, single, basal layer of the epidermis composed of basal cuboidal-shaped cells. These cells are the <em>precursor of keratinocytes</em>, this is why this layer is also called germinativum. In this basal layer, there are also <em>Merkel cells</em> as well as melanocytes.
During the phase of anaphase, each pair of chromosomes separate into two identical, independent chromosomes.
During the last phase of telophase the sisters chromatids reach opposite pole. The small nuclear vesicles in the cell begin to re-form around the group of chromosomes and at each end. Hope it helped :)
