If a sample of the heat-killed bacteria is treated with a DNase would you expect transformation to occur? Explain.

Describe the dna structure using the terms nucleotides, backbone, and orientation.

Alona [7]

The term DNA stands for deoxyribonucleic acid and contains genetic information in its double-stranded helical structure.

Explanation:

A nucleotide can be said to be the basic building block of the DNA molecule. Each of these nucleotides is composed of three components:

A phosphate group
A sugar group
A nitrogen base

The genetic code contained within the DNA is determined by the sequence/order in which these bases occur.

The DNA backbone is made up of the sugar-phosphate nucleic acids framework. These groups occur in an alternating manner, in repeating patterns.

The structure of DNA is fairly regular, as in the following parameters are constant - orientation, length of the strand, width and number of nucleotides. These double-stranded molecules are asymmetrical, with the two disjoint strands intertwined with each other, connected by means of hydrogen bonds.

What is the probability that each of the following pairs of parents will produce the indicated offspring? (Assume independent as

ASHA 777 [7]

Answer:

(a) AABBCC × aabbcc->AaBbCc → 1

(b) AABbCc × AaBbCc->AAbbCC → 1/32

(c) AaBbCc × AaBbCc->AaBbCc → 1/8

(d) aaBbCC × AABbcc->AaBbCc → 1/2

Explanation:

In such cases we calculate the probability of each allelic pair separately.

(a) AABBCC × aabbcc -> AaBbCc

Aa Aa Aa Aa Bb Bb Bb Bb Cc Cc Cc Cc

↓ ↓ ↓

4/4 = 1 4/4 = 1 4/4 = 1

In case of gene A, out of the 4 probable allelic combinations, 4 will be Aa so the probability is 4/4 = 1.

In case of gene B, out of the 4 probable allelic combinations, 4 will be Bb so the probability is 4/4 = 1.

In case of gene C, out of the 4 probable allelic combinations, 4 will be Cc so the probability is 4/4 = 1.

So, the total probability of getting AaBbCc = 1 x 1 x 1 = 1.

(b) AABbCc × AaBbCc -> AA bb CC

AA AA Aa Aa BB Bb Bb bb CC Cc Cc cc

↓ ↓ ↓

2/4 1/4 1/4

In case of gene A, out of the 4 probable allelic combinations, 2 will be AA so the probability is 2/4.

In case of gene B, out of the 4 probable allelic combinations, 1 will be bb so the probability is 1/4.

In case of gene C, out of the 4 probable allelic combinations, 1 will be CC so the probability is 1/4.

So, the total probability of getting AA bb CC = 2/4 x 1/4 x 1/4 = 1/32.

(c) AaBbCc × AaBbCc -> AaBbCc

AA Aa Aa aa BB Bb Bb bb CC Cc Cc cc

↓ ↓ ↓

2/4 2/4 2/4

In case of gene A, out of the 4 probable allelic combinations, 2 will be Aa so the probability is 2/4.

In case of gene B, out of the 4 probable allelic combinations, 2 will be Bb so the probability is 2/4.

In case of gene C, out of the 4 probable allelic combinations, 2 will be Cc so the probability is 2/4.

So, the total probability of getting AaBbCc = 2/4 x 2/4 x 2/4 = 1/8.

(d) aaBbCC × AABbcc->AaBbCc

Aa Aa Aa Aa BB Bb Bb bb Cc Cc Cc Cc

↓ ↓ ↓

4/4 = 1 2/4 4/4 = 1

In case of gene A, out of the 4 probable allelic combinations, 4 will be Aa so the probability is 4/4 = 1.

In case of gene B, out of the 4 probable allelic combinations, 2 will be Bb so the probability is 2/4.

In case of gene C, out of the 4 probable allelic combinations, 4 will be Cc so the probability is 4/4 = 1.

So, the total probability of getting AaBbCc = 1 x 2/4 x 1 = 1/2.
