Answer:
The correct answer is the last option, that is, multigene families are similar or identical genes, whose evolution took place by gene duplication.
Explanation:
A member of a family of the associated proteins encrypted by an array of identical genes is known as a multigene family. It is considered that the origination of the multigene families has resulted due to the variation and duplication of a single ancestral gene.
The multigene families make the assembly of the proteins comparatively quickly, as it assists in the simultaneous transcription of various genes at distinct locations.
There's a first one, that's called the leading strand. Its the parens strand of the DNA which runs in the 3' to 5' direction to the fork.......
BioSafety Level (BSL) 3 labs,
perform work with indigenous or exotic agents that may cause serious or
potentially lethal diseases through the inhalation exposure. Biological Safety
Levels (BSL) are a sets of protections assigned to the activities that occur in
specific biological laboratories. BSL protects laboratory workers, the
surrounding environment and also the community.
The correct option is D. This is because, mucus, inflammation and fever perform different functions in the immune system.The mucus membrane produces mucus which traps microbes. Inflammation refers to a localized tissue response which occurs when a tissue is damaged. Fever inhibits bacterial growth and speed up the rate of healing of a damaged tissue.
Answer: Y represents carbon and z is oxygen which gives CO2
Explanation: To photosynthesis to occur Carbon has to reacts with oxygen to give carbondioxide (Co2) which then combines with hydrogen (H2) and oxygen to give water (H20) the reaction gives glucose (C6H12O6).
Equation for photosynthesis = 6CO2+6H20- C6H12O6
