An intron is a non-coding region of DNA. During alternative splicing, introns are removed.
- During eukaryotic transcription, a fragment of DNA (e.g., a gene) is used as a template to synthesize a complementary RNA sequence, usually a precursor mRNA (pre-mRNA).
- Subsequently, this pre-mRNA is processed by a mechanism called alternative splicing in order to produce a mature mRNA which is then used as template to synthesize a protein by a process called translation.
- During alternative splicing, non-coding regions of a gene called 'introns' are removed, where coding regions called 'exons' are spliced back together.
- If a cell transcribed and translated a gene’s intron by mistake, then additional amino acids would be inserted into the protein and therefore the resulting protein will be longer than normal.

Answer:
protein capsid
Explanation:
virus is a disease causing agent containing a protein capsid which is made up of protein called Capsomere. The capsid contain the genetic information or material of virus.
Virus which do not contain envelop is called naked virus.
the uses of capside are to protect the genetic material, transfer the genome and interaction with host cell.
Answer;
Glucose
The nutrient that can be used to produce energy in the absence of oxygen is glucose.
Explanation;
Production of energy without using glucose is called anaerobic respiration. During this type of respiration less energy is released than the case of aerobic respiration. This is because the breakdown of glucose is incomplete. Anaerobic respiration produces an oxygen debt, which is the amount of oxygen needed to break lactic acid to carbon dioxide and water.
<span>B. Knowledge and valuable resources are shared among scientists.
Being involved in a research community could provide a higher chance to researchers the privilege to avail resources, knowledge and supporting evidences that might relate or support the current study the research wants to delve into.</span>
Answer: Humans and greater primates excrete water, broken down proteins and Urea. Many things cause unusual urine, Urea gives urine its yellow color a lack of urea can mean kidney failure. however it's hard to tell a lack of urea by just looking at urine as drinking excessive amounts of water turns the color clear and drinking caffeine turns the color reddish or brown so lab testing must be done
