Hello, Leah082656. There are many heated arguments over discussing stem cell research because of these two moral principals: the duty to prevent or alleviate suffering and the duty to respect the value of human life. In order to get embryonic stem cells, the embryo has to be destroyed. Although this is a huge controversial problem, by researching this could actually save and treat many other people. Some people are for it because it saves multiple people in the process, and some do not like this because it is killing an embryo. Whatever your stance is on this debate, these are the two sides that people debate over. I hope I helped!! Have a great day. :)
Answer:
You can determine its genotype by crossing it to an animal with a recessive genotype, llbb.
Explanation:
A test cross is performed when there is an individual with an unknown genotype and we desire to know if it is a heterozygote individual or a dominant homozygote individual.
The cross occurs between the individual of unkown genotype and a recessive homozygote individual.
Answer:
The answer is XX.
Explanation:
Let us say that X is the dominant gene and x is the recessive gene for the height of the pea plants. Pea plants need to be homozygous or heterozygous to have the short phenotype which means it needs to have the genotype xx or Xx.
The F2 offspring has a ratio of 74,5% tall plants and 25,5% short plants. For these results, the stem height pea plant needs to be homozygous which is an XX genotype for the tall pea plant.
I hope this answer helps.
Answer:
The consequences will depend on the type of mutation. For example, if the mutation is synonymous it will not have negative effects on the cell function. On the other hand, if the mutation produces amino acid diversity it may cause loss of function
Explanation:
Primase is an RNA polymerase that adds RNA nucleotides to the complementary DNA strand in order to prepare it for the RNA polymerase III during transcription initiation
Answer:
Explanation:
The RNA codon for valine is anything starting with 'GU' (GUU, GUC, GUA, GUG). Valine anticodons are complementary to these sequences; that is, anything starting with 'CA' (CAA, CAG, CAU, CAC). Codon tables like the one below are really helpful in this regard.
