A point mutation will cause the cell to make an incomplete polypeptide if the mutation results in a stop codon. Is this true or false

Answers

Answer 1

Answer: True - if there is a mutation in the genetic code that causes a stop codon then the rest of the code will not be read and translated, resulting in an incomplete polypeptide

Before using any chemical in the lab, why should one first read the Material Safety Data Sheet (MSDS)? This is important for laboratory safety. The MSDS tells where to purchase chemicals. The MSDS provides the chemical formulas. This is important for analyzing experiments.

Answers

The right answer is; This is important for laboratory safety.

Before using any chemical in the lab, one should first read the Material Safety Data Sheet (MSDS) because it is important for laboratory safety.

A Material Safety Data Sheet (MSDS) is a technical document that contains detailed information about the protective measures to take, and the possible hazards of a chemical. The Material Safety Data Sheet (MSDS) is available for all the chemicals used in the laboratory and it may be written, printed or electronic.

A. This is important for lab safety.

Which type of selection leads to increased phenotypic and genetic variation?A. directional selection
B. disruptive selection
C. stabilizing selection
D. species selection

Jezelyn needs to create a project that shows reproductive isolation in action and decides to make a video. Which of the following would make the best project?
A. a video that shows a large river that has penguin populations on both sides
B. a video that shows penguin species that have different mating dances
C. a video that shows a penguin that is laying eggs
D. a video that shows penguins in a tidal pool and an open ocean

Answers

The answer to the first question is letter B. This is because disruptive selection is opposite to stabilizing selection which decreases genetic variation or genetic diversity. Among the choices on the second question, the second option (B) is the most plausible because it could mean "difference within the same specie". This video would likely to show sexual isolation.

Both of the question is B. Hope it help!

how is the expression of sex linked genes both similar to and different from the expression of autosomal genes?

Answers

Sex chromosomes contain genes that determine the sex of a person. Two X chromosomes result in a female and one X plus a Y result in a male.

In those chromosomes, there are genes specific for each gender, and in those chromosomes, there are genes that code for certain traits- the sex-linked traits.
These traits will be inherited according to the sex chromosomes they receive from their parents. Women recieve one X from the mother and the other from the father while men recievethe X from the mother and the Y from the father).

This will cause a difference in the expression of genes because women can become carriers of a certain disease while men either manifest it or don't (there are no carriers since the X chromossome is different than the Y)

In autosomal genes, the expression doesn't depend on the gender since the autosomal chromosomes contain genes that code for the same trait, and so the expression on autosomal genes in men and women are similar.

first of all you are already known about the genes found in male and female Autosomal genes are not expressed by the X or Y chromosome. Sex linked genes are expressed by the X or Y chromosome. Expression of autosomal and sex-linked genes are the same in that both require undergo meiosis and crossing-over may occur and transcription and translation of genes are required.
