Answer:
4) Some people consider human genetic experiments
unethical.
Explanation:
1) Humans have DNA that is structurally very different from
other mammals.
2) Cloning can only he performed on animals that normally
reproduce asexually.
3) Human genes are made of too many different types of
simple sugars.
4) Some people consider human genetic experiments
unethical.
The statement that provides the most likely reason that a human has not yet been cloned is that some people consider human genetic experiment unethical.
<em>Option 1 is incorrect because human DNA is similar in structure to other living organisms with components such as a phosphate group, a deoxyribose sugar and purine/pyrimidine bases.</em>
<em>Option 2 is incorrect because cloning is not limited to asexually reproducing organisms only. Sheep, for example, produces only sexually and has been successfully been cloned.</em>
<em>Option 3 is incorrect because human genes, just like every other organisms is consist of DNA with deoxyribose pentose sugar being one of the components. The situation of too many different types of simple sugars doe not arise.</em>
The correct option is 4.
Answer:
A truncated protein refers to a protein that gets shortened due to a mutation, which does not allow the process of translation to take place properly. The formation of a truncated protein can take place due to a frameshift mutation of one or two base pairs. In such kind of mutation, a single or two base pairs get withdrawn from the sequence resulting in the formation of a completely changed triplicate codon sequence, which may result in the generation of a truncated protein comprising a different set of amino acids.
A nonsense mutation can also result in the formation of a truncated protein. A nonsense mutation generally codes for certain kinds of amino acid, however, post mutation can get converted into a stop codon. This transformation can result in the formation of a truncated protein.
Deletion or insertion at the chromosomal level can also result in the formation of a truncated protein. As insertion and deletion of a certain concentration of DNA can probably lead to the formation of a novel codon that can either be a nonsense codon or a stop codon, which may eventually result in the formation of a truncated protein.
Hence, the correct answers are statements 1st, 2nd, 3rd, 4th, and 6th
Answer:
Start by introducing your topic. What are you learning about? How will it impact your life or the lives of others? Give some context, or background information, to your audience if it is an uncommon topic. Try not to explain anything about your experiment or the data that you collected. Share what you were trying to find out, what your problem was. Conclude it by introducing how you started to research.
Answer:
Heterozygous
Explanation:
A genotype describes which alleles of a particular gene a person has. We have two copies (alleles) of each gene, one from mom and one from dad, but these alleles can be different.
Often, these alleles can be dominant and recessive with regards to eachother. The dominant allele will always be displayed in the phenotype, whereas the recessive will not be presented, as it is masked by the dominant gene. If you have two copies of the dominant gene (homozygous) you will display the phenotype associated with the dominant genotype. If you have two copies of the recessive gene (homozygous) you will display the phenotype of the recessive gene.
If you have one copy of each (heterozygous), you will display the phenotype of the dominant gene, even though your genotype has a copy of each.
