What is the nucleotide sequence of an mrna strand that has been transcribed from the dna sequence ggtagc?
lys-0071 [83]

CCAUCG  is the nucleotide sequence of an mrna strand that has been transcribed from the dna sequence ggtagc.

<h3>What is a nucleotide sequence?</h3>
  • Transfer RNAs interact with the ribosome system to translate a nucleic acid sequence, known as a messenger RNA or mRNA, into the protein it encodes.
  • Transfer RNAs partition the nucleic acid sequence into triplet codons, each of which specifies one amino acid, by binding to three nucleotides at once.
  • The sequence does not contain punctuation signals to indicate which reading frame should be used, hence the nucleic acid can be read in three different phases or reading frames depending on the point at which division into codons begins.
  • An addition or deletion in the nucleic acid sequence that changes the translation process from one reading frame to another is known as a frameshift mutation.

To know more about the nucleotide sequence, refer:

HELP.
Kamila [148]

Answer:

The mass of tin is 164 grams

Explanation:

Step 1: Data given

Specific heat heat of tin = 0.222 J/g°C

The initial temeprature of tin = 80.0 °C

Mass of water = 100.0 grams

The specific heat of water = 4.184 J/g°C

Initial temperature = 30.0 °C

The final temperature = 34.0 °C

Step 2: Calculate the mass of tin

Heat lost = heat gained

Qlost = -Qgained

Qtin = -Qwater

Q = m*c*ΔT

m(tin)*c(tin)*ΔT(tin) = -m(water)*c(water)*ΔT(water)

⇒with m(tin) = the mass of tin = TO BE DETERMINED

⇒with c(tin) = the specific heat of tin = 0.222J/g°C

⇒with ΔT(tin) = the change of temperature of tin = T2 - T1 = 34.0°C - 80.0°C = -46.0°C

⇒with m(water) = the mass of water = 100.0 grams

⇒with c(water) = the specific heat of water = 4.184 J/g°C

⇒with ΔT(water) = the change of temperature of water = T2 - T1 = 34.0° C - 30.0 °C = 4.0 °C

m(tin) * 0.222 J/g°C * -46.0 °C = -100.0g* 4.184 J/g°C * 4.0 °C

m(tin) =  163.9 grams ≈ 164 grams

The mass of tin is 164 grams
