To translate messenger RNA, or mRNA, use an amino acid table to help you figure out the condo sequence in transfer DNA known as tRNA. Genes in DNA are like coded recipes for proteins. Cells transcribe there coded recipes onto an messenger mRNA transcripts and export it out of the nucleus onto the cytoplasm of the cell.
Hope this helps :)
1. The right answer is biological.
The nonspecific response, which constitutes innate immunity, works by not taking into account the type of disease it is fighting. It is the first line of defense against an infection. Several types of mechanisms intervene during this response:
* physical barriers (skin, mucous membranes, tears...)
* inflammation;
* cells of innate immunity:
* complement: it is a group of proteins that plays a role in immunity.
2. The right answer is proteins.
The complement system is a group of 25 known serum proteins, part of the innate immunity. Twelve (12) of these proteins are directly involved in the mechanisms of elimination of pathogens, the others finely regulate the activity of the former to avoid an autoimmune reaction.
3. The right answer is inflammation.
Inflammation is the body's stereotyped immune system reaction to external aggression (infection, trauma, burn, allergy, etc.) or internal (cancerous cells). Inflammation is a universal process, involving all tissues (called ubiquitous); it involves innate immunity as well as adaptive immunity.
Answer:
9/32 Pink, Tall and Normal individuals Rr Tt Nn
Explanation:
<u>Available data:</u>
- Red color RR
- Pink color Rr
- White color rr
- Normal NN and Nn
- Symmetrical nn
- Tall TT and Tt
- Dwarf tt
1st Cross:
Parental) rr TT NN x RR tt nn
F1) 100% RrTtNn
2nd Cross:
Parental) Rr Tt Nn x Rr Tt Nn
Knowing that these three genes assort independently, then we can infer that the F2 will have the next phenotypic proportions for each gene:
RR= 1/4 Red
Rr= 2/4 Pink
rr=1/4 White
TT + Tt= 3/4 Tall
tt=1/4 Dwarf
NN + Nn = 3/4 Normal
nn=1/4 Symmetrical
- The proportion of the F2 plants that will resemble Rr Tt Nn (Pink, tall, Normal) in Phenotype
Rr= 2/4 pink
TT + Tt= 3/4 Tall
NN + Nn = 3/4 Normal
2/4 x 3/4 x 3/4 = 18/64= 9/32
