Protein synthesis consumes four high-energy phosphate bonds per added amino acid. Transcription consumes two high energy phosphate bonds per added nucleotide. Calculate how many protein molecules will have been made from an individual mRNA at the point when the energy cost of translation is equal to the energy cost of transcription. Assume that the nucleotides in the coding portion of the mRNA constitute 5% of the total that are transcribed.
Answers
Answer:
30 protein molecules per mRNA molecule
Explanation:
In this problem, it is necessary to have into account that the transcriptional process requires six (6) phosphate bonds to synthesize one (1) codon (i.e, each three nucleotides), and also discards 95% more energy to make mRNA, it means 19 times this amount of energy >> 6 x 19 = 114 bonds. In consequence, transcription requires 120 phosphate bonds (6 + 114 = 120), while translation requires four (4) phosphate bonds per codon. From this deduction, it is possible to find the number of protein molecules synthesized with regard to the energy cost of the translation process and the transcriptional process >>> 120 bonds (transcription) /4 bonds (translation) = 30 protein molecules.

What observation supports the claim that earth rotates
Answers
Answer:
The most direct observational evidence for Earth's orbital motion is the apparent shift of nearby stars after six months, as the Earth moves from one side of its orbit to the other. Because of the large distance to even the nearest start, this parallax shift is too small to been seen without a telescope.

Answers
The corresponding nucleotide sequence is present on the coding strand. No complementary sequence exists on the template strand.
What changes occur in complementary strand from template?The DNA strand from which the mRNA is produced is known as the template strand. The DNA strand opposite the template strand is known as the coding, or non-template, strand, and it has the same sequence as mRNA except T to U substitutions.
The template strand, one of the two exposed DNA strands, acts as a model for transcription.
The RNA product is essentially identical to the non template (or coding) strand of DNA and is complementary to the template strand.
Therefore, AUG CCU AUU GAU GGC CCA UAA GUU is the complementary strand of mRNA.

One species called the naked mole-rat, has some unique differences. They have a social structure similar to that of ants and bees, they are smaller in size and are mostly ectothermic. They live in harsh, dry scrub land habitats and forage mainly on underground tubers which are widely dispersed. Why you think this species evolved back to an ectothermic life style rather than staying endothermic like all other mammals
Answers
Answer:
May be of the environment they live or genetics.
Explanation:
This naked mole rat species evolved back to an ectothermic life style rather than staying endothermic like all other mammals because of the environment they live or change in the genetic makeup. The main reason for this evolution may be the environmental they lives or through the change in genetic makeup of this naked mole rat species so both factors can contribute in the evolution.

1.) A person walks 12.5 km in 1.9 h. What is the person's
average velocity in km/h and m/s?
Answers
Answer:
1. 6.56 km/hr
2. 1.83 m/s
Explanation:
The average velocity/speed can be calculated using the formula;
Average speed/velocity = distance/time
According to the information provided in the question, distance = 12.5km, time = 1.9h
Average velocity in km/hr = 12.5/1.9
= 6.578
= 6.56km/hr
However, in order to calculate the average speed in m/s, we have to convert distance in km to m, and time in hour to seconds.
1km = 1000m
12.5km = 12.5 × 1000
= 12500m
1 hour = 3600seconds
1.9hours = 1.9 × 3600
= 6840seconds
Average velocity = 12500/6840
= 1.827
= 1.83m/s

Polymerase Chain Reaction (PCR) technology is used for
a. DNA identification
b. DNA repair
c. DNA amplification
d. DNA cleavage
Answers
Answer:
The correct answer is c.
Explanation:
Polymerase Chain Reaction (PCR) technology is an in vitro enzymatic method that allows the amplification of a specific DNA sequence, that is, it is the DNA amplification technique by means of the polymerase chain reaction (PCR) is a technique that consists of the in vitro amplification of a specific DNA fragment. To carry out the amplification experiment, it is necessary to know, at least partially, the sequence of the fragment to be amplified (a gene, a part of a gene, a non-coding region, ...). Basically, it is about replicating the same DNA fragment over and over again and, for this, we must do in vitro what cells do in vivo to replicate their DNA. Generally, PCR begins with the denaturation or separation of the DNA double helix by heating the sample to a temperature between 94 and 96 ° C to break the hydrogen bonds that joined them, in this way each chain remains as a template for the synthesis of a new complementary strand of DNA.
