In _____, one allele is dominant to a recessive allele.incomplete dominance
simple dominance
codominance
pleiotrophy

Answers

Answer 1
Answer:

Answer: The correct answer is- " Simple dominance".

Simple dominance refers to the expression of one allelic form of a gene (that is dominant) over the other form (that is recessive).

Example- T allele is dominant that represents tall plant height over t (for dwarf), which only expresses in the absence of dominant allele.

On the contrary, pleiotropy means one gene is responsible for more than one characteristic or phenotypic trait of the organism.

Codominance means equal expression of both the alleles (like AB blood group) of a gene. Incomplete dominance occurs when none of the alleles is completely dominant resulting in an intermediate phenotype.


Thus, simple dominance is the right answer.


Answer 2
Answer: Simple dominance is where one allele is dominant while the other is recessive.

The sequence of in a Dna molecule determines the protein that will be produced

Answers

Answer:

True

Explanation:

The DNA sequence determines the protein that is going to be produced. The first step is the transcription where DNA sequence is transcribed to mARN. After the mARN is formed this will go out of the nucleus and into the cytoplasm. In the cytoplasm the mARN, together with the tARN and the ribosome will make a protein by a process called translation. In this process the ARN sequence is read to give and join the amino acids that are required to form the protein.

Translation is divided into three phases: initiation, elongation, and termination. In this tutorial you will gain an understanding of the components and mechanisms of translation.Although the process of translation is similar in bacteria and eukaryotes, there are some important differences. State them ?

Answers

Answer:

Translation can be described as a process in which proteins are synthesized.

Differences between the prokaryotic and eukaryotic translation are:

  • In prokaryotes, transcription and translation occur simultaneously. In eukaryotes, transcription and translation are two different process. Transcription occurs in nucleus whereas translation in cytoplasm.
  • In prokaryotes, the 5' end of mRNA is available for translation whereas the mRNA of eukaryotes has to under go changes before translation begins.
  • The ribosome type for prokaryotic translation is 70S and for for eukaryotes is 80 S.

What kind of relationship would a mouse and a rabbit have?A. competitive relationship
B. communalistic relationship
C. mutuality relationship
D. parasitic relationship

Answers

This is a fairly simple question that you can answer with the process of elimination.
A competitive relationship is a relationship between members of the same or different species in which individuals are adversely affected by those having the same living requirements, such as food or space.
A commensalistic relationship is a relationship between two different species where one species enjoys a benefit and the other isn't significantly affected.  
A mutalistic relationship is a relationship between two different species where both species receive a benefit from the other.
A parasitic relationship is a relationship between two different species where the parasite (symbiont) benefits from the host and the host is harmed.
