Answer:
The binomial name consists of a genus name and specific epithet. The scientific names of species are italicized. The genus name is always capitalized and is written first; the specific epithet follows the genus name and is not capitalized. There is no exception to this.
Answer:
substitution - a base was changed
Explanation:
The nucleotide sequence CTT was changed to the sequence CAT. The T was substituted with an A. This changed the encoded amino acid from Glu to Val.
An insertion is where an additional base is added (e.g. if the sequence changed from CTT to CATT)
A deletion is when a base is lost (e.g. if the sequence changed from CTT to CT)
Answer:
<em>As scientists learned more about genetics and biochemistry , some organisms were moved out of existing kingdoms and into new ones.</em>
Explanation:
As the researches in the scientific world continued, scientists realized that there were, in fact, many genetic diversities present in organisms which were placed in the same groups. Hence, they realized that due to these differences these organisms should not be kept in the same group. As a result, the groups in the classification system increased.
Carolus Linnaeus just grouped organisms based on their features. But today, scientists classify organisms based on various perspectives such as the evolutionary history, genetic similarities etc.

Answer:
a. to treat a disease characterized by a gene that is not expressed.
Explanation:
The RNA interference (RNAi) technique is widely used in molecular biology to inhibit target gene expression at the post-transcriptional level. The RNAi technology uses small interfering RNAs (siRNAs) consisting of 18-22 nucleotides that bind to complementary acid nucleics (i.e., DNA and RNA), thereby inhibiting target gene expression. Recently, it has interestingly been discovered that small RNA sequences targeting promoter regions can also be used to activate the expression of endogenous target genes through a mechanism called RNA activation (RNAa).
