Cytosine makes up 42% of the nucleotides in a sample of DNA from an organism. Approximately what percentage of the nucleotides in this sample will be thymine?a) 8%b) 16%c) 31%d) 42%e) It cannot be determined from the information provided

Answers

Answer:

Percentage of Thymine is 8%

Background Knowledge:

DNA molecule is composed of four type of nucleotides Adenine, Guanine, Cytosine and Thymine. DNA is double stranded molecule in which one strand form complementary base pairing with other strand i.e Adenine present on one strand of DNA always form complementary base pairing with thymine of other strand similarly Guanine present on one strand of DNA always form complementary base pairing with Cytosine of other strand.

Explanation:

As Cytosine percentage in DNA is 42% hence Guanine percentage is also 42%.

Total percentage of both Cytosine and Guanine become

42 + 42 = 84%.

Percentage remained for both Adenine and Thymine is

100 - 84 = 16%

So Percentage of Thymine is 8%

If black and white true-breeding mice are mated and the result is all gray offspring, what inheritance pattern would this be indicative of? dominance
codominance
multiple alleles
incomplete dominance

Answers

Answer:

Option B, Co-dominance

Explanation:

This is an example of codominance inheritance pattern.

When two alleles representing two different characteristic traits are expressed equally in the offsprings resulting from a cross, then this genetic inheritance pattern is called as codominance .

For example -

A red flower with genotype "RR" is crossed with a white flower "rr" resulting into pink color offsrping with genotype "Rr"

Here, both the red and white traits of flower color are expressed equally thereby giving pink color to the offspring flower.

The same thing is happening in case of true breeding black and white mice.

Hence, option B is correct

Answer:

D.

Explanation:

In a heterozygote, expression of two contrasting alleles such that the individual displays an intermediate phenotype is called incomplete dominance.

Why is interphase necessary if a cell is to successfully divide

Answers

Answer: The interphase is one of the most important part of the cell cycle, 90% of the cell's life takes part in this stage. During interphase the cell is preparing for division. Cellular organelles are doubled up in number. The DNA is then replicated and more proteins are then synthesized. This stage prepares the cell's materials before it undergoes mitosis or meiosis.
