<span>Anemia
is a condition that occurs in blood in which a person lacks enough healthy
blood cells or haemoglobin. The latter is the main part of the red blood cells
which binds with oxygen and transports it to the rest of the body. One of the
causes of anemia, as mentioned above, is fatigue. The condition can also be
associated with the deficiencies in vitamins and minerals (iron). </span>
Answer: 5' TTGGCTCACCT 3'
Explanation:
The two DNA strands are <u>antiparallel</u>, meaning that if the template strand goes from the 3' end to the 5' end, then the complementary strand will be from the 5' end to the 3'end.
During DNA replication, DNA polymerase adds nucleotides according to the <u>base pairing rules</u>:
Therefore, according to this understanding, the given strand:
3' AACCGAGTGGA 5'
Matches with the following
Hope this helps!! :)

Answer:
The presence of smog in the atmosphere and exploitation and burning of coal
Explanation:
The "smog" can be observed as dark low clouds in the cities. These are formed by accumulation of gases such as: CO2, soot, smoke and dust in suspension. If the atmospheric concentration of the main gases responsible for the greenhouse effect that was maintained in 2016 is maintained, the average temperature of the Earth will have risen 1, 3 ° C in 2020 and 3 ° C in 2070.
In the process of using coal, important environmental damage occurs because when burning it releases large amounts of greenhouse gases.
The damage caused by coal combustion is much greater when poor quality fuel is used, because the impurities it contains are converted into sulfur oxides and other toxic gases.
In the production of electricity, about 5 tons per year are used, causing havoc in terms of pollution
Answer:
The 4 codons that code for Alanine are :-
GCU ; GCC ; GCA ; GCG ;;
codon for Valine :-
GUU ; GUC ; GUA ; GUG
Part A. Total number of possible mutations are 36.
GCU
GCU --> GCC , GCA , GCG
GCU --> GUU , GAU , GGU
GCU --> UCU , CCU , ACU
GCC
GCC --> GCU , GCA , GCG
GCC --> GUC , GAC , GGC
GCC --> UCC , CCC , ACC
GCA
GCA --> GCU , GCC , GCG
GCA --> GUA , GAA , GGA
GCA --> UCA , CCA , ACA
GCG
GCG --> GCU , GCC , GCA
GCG --> GUG , GAG , GGG
GCG --> UCG , CCG , ACG
Part B. Silent mutations occur when the last base of the codon is substituted with other bases.
Thus, the Total number of silent mutations are 12.
Part C. Conservative mutations occur when the second base of the codon is substituted to a "U".
Thus, the Total number of conservative mutations is 4.
