If a trna molecule has an anticodon which reads aug, what will it match up with and what amino acid is it carrying?

a. it is carrying arginine and will match with a cgu codon on the mrna.
b. it is carrying methionine and will match with a tac codon on the dna.
c. it is carrying methionine and will match with a uac codon on the mrna.
d. it is carrying tyrosine and will match with a uac codon on the mrna

is it a?

no, it's not a. it's d) It is carrying tyrosine and will match with a UAC codon on the mRNA

if the tRNA is AUG, then the mRNA would be UAC.

U goes with A

A goes with U

T goes with A

G goes with C

C goes with G

to find out how which amino acid is it you can use the chart below, which should be tyrosine. :)

1) gene flow

- it is described as the transfer of genes from one population to another population so that frequency of gene is increased.

-a zebra migrates to join a different herd of zebras.

2) natural selection

- a mechanism of evolutionary change in which individuals with advantageous traits survive and reproduce whereas the others ( those that can not adapt) eliminate from the population.

-competition for sunlight leads to taller trees.

3) mutation

- permanent change in the nucleotide sequence of dna ( genetic material) that could have harmful or useful consequences.

-the dna of a snake changes to make its venom stronger.

4) genetic drift - it is a random phenomenon ( that occurs by chance such as fire) that results in change in the gene frequency in a small population.    

-a grassfire randomly sweeps through a population of buffalo and kills most of the animals.
