If cysteine is specified by the codons UGC and UGU, what are the anticodons present on tRNAs that carry cysteine?
MrRissso [65]

Answer:

AGC and ACA

Explanation:

Codons and anticodons are present in the form of triplets.Codons are present on the coding strand of DNA and on mRNA and their anticodon is present on transfer RNA.When codon present on mRNA binds to its anticodon on tRNA then appropriate amino acid is carried by tRNA on ribosomes for protein synthesis. For example, AGC and ACA anticodons are present on tRNA that binds to UGC and UGU on mRNA for amino acid cysteine.

Explanation:

PMR is a healthy coping skill normally learned in any kind of psychiatric business. For example, I learned PMR while I was inpatient at a behavioral health unit. The way we did PMR was that we'd sit up in our chairs and start from the toes and on up. We squeezed our toes together for a few seconds and then released and then we'd do it a second time. After the toes, it would move up to the feet and we'd use the same process for that and for the rest of the joints.
