A segment of dna has 320 nitrogen bases. if 40 of them are cytosine, how many are thymine

Biology
1 answer:
NISA [10]3 years ago
8 0
Correct answer - 120 for Thymine.

Why? - 320 Nitrogen bases.
Cytosine = 40, Cytosine = Guanine.
Therefore Guanine = 40.
320 - 80(Cytosine and Guanine)
240.
Adenine and Thymine = ?
Adenine = x and Thymine = x.
2x = 240.
X = 240/2
X = 120.
Adenine 120, Thymine = 120, Cytosine = 40 and Guanine = 40.

In hamsters, we can examine the genes for coat color and eye color which are linked:B = brown coat, b = white coat, G = green ey
Inessa [10]

Answer:

10.2 cM

Explanation:

Given,

pure breeding parent 1 : BBgg = brown coat and pink eyes

pure breeding parent 2 : bbGG = white coat and green eyes

BBGG X bbgg = F1 = BbGg ( All are brown with green eyes )

When F1 progeny is test crossed with white coat and pink eyes hamster:

BbGg X BbGg = F2 =

brown, pink eyes = 99 = parental

white, green eyes = 103 = parental

brown, green eyes = 12 = recombinant

white, pink eyes = 11 = recombinant

Recombination frequency =

(total number of recombinants / total progeny ) * 100

= [( 11 + 12 ) / ( 99 + 103 + 12 + 11 )] * 100 = (23/225)*100 = 0.102 * 100 = 10.2 %

1 % recombination frequency = 1 cM distance between genes

Hence, the distance between B and G gene is 10.2 cM

A mutation can be passed on to offspring if it occurs in the
aalyn [17]

I believe the correct answer is chromosome.

<h2>Explanation:</h2>

We inherit 23 chromosomes from our mother and another 23 chromosome pairs from our father. You have to inherit a defective chromosome for you to get the mutation. This is what is called germ line mutation usually carried in the sperm or ovum. Of the 23 chromosomes, 22 are autosomal and 1 is chromosomal meaning of the 23 one of them is X and another one is . You get the Y from your father and the X from your mother.
