A part of an mrna molecule with the following sequence is being read by a ribosome: 5' ccg-acg 3' (mrna). the anticodon loop of
monitta

The first trna's anticodon loop, which will complement this mrna, is 3' GGC 5'.

<h3>What is anticodon ?</h3>

A complementary codon in messenger RNA binds to a triplet of nucleotide bases in transfer RNA that identifies the amino acid delivered during protein synthesis at a ribosome.

A codon is a trio of nucleotides, or triplet, that can be found on mRNA and codes for a certain amino acid when it is translated. A bond is created when an anticodon, which is a three-nucleotide sequence on tRNA, meets with the matching sequence on mRNA.

Each tRNA has a trio of bases known as an anti-codon. to determine the entire anti-codon sequence required to match a certain strand of mRNA. to match the complementary nucleotides in the mRNA sequence.

1) the average rate of reaction in the first minute
iragen [17]

1. 0+15+30+45+60=150/5=30 s

0+10+16+22+27=75/5=15 cm^3

then, 15/30= 0.5 cm^3/s(average rate of rxn)

2. 0+15+30+45+60+75+90+105+120=540/9=60 s

0+10+16+22+27+31.50+36+39.5+42=224/9=24.89cm^3

then, 24.89/60=0.414cm^3/s (avrg rate of rxn)

3. overall rxn add all the time divide by 12 and the volume add them too and divide by 12. after take average volume divide by the average time to get the average rate of overall rxn

4. 16/30= 0.533cm^3/s

5. 39.5/105= 0.37cm^3/s
