Answer:
Contamination of the control sample (negative control) with DNA
Explanation:
The Polymerase Chain Reaction (PCR) is a technique widely used in molecular biology laboratories to amplify a target DNA fragment using primer pairs and DNA polymerase. In PCR experiments, it is imperative to include both positive and negative controls. The positive control refers to the amplification of a PCR product (amplicon) of known molecular size during PCR reaction in order to ensure the correct molecular weight of the target DNA fragment. The negative control refers to the inclusion of a sample without DNA in order to ensure that no contamination with DNA has occurred in the other samples.
Answer:
Explanation:
Cerebral Palsy is a brain injury it occurs while the brain is developing this could be before, during, or after birth. Mutation which is a sudden heritable change in the genome of an individual can result into cerebral palsy when the child is still developing. Mutation affects the gene changing it from it normal state to an abnormal one some mutation can be beneficial but for palsy it is detrimental one affecting the growth and development of the child.
severe jaundice in the infant could also lead to cerebral palsy in an infant child
This damage affects child’s muscle control, muscle coordination, muscle tone, reflex, posture and balance.
It can also impact a child’s fine motor skills, gross motor skills, and oral motor functioning
Answer:
All matter is made up of atoms and molecules that are constantly moving. When heat is added to a substance, the molecules and atoms vibrate faster. As atoms vibrate faster, the space between atoms increases. ... The atoms can get closer which results in the matter contracting.
Explanation:
Exponential is not a type of population distribution.
Ans: Most genes contain the information needed to make functional molecules called proteins. (A few genes produce regulatory molecules that help the cell assemble proteins.) The journey from gene to protein is complex and tightly controlled within each cell.
