How is this information carried within the DNA

1 answer:

6 0

<h2>Answer: Genetic information is carried in the linear sequence of nucleotides in DNA. Each molecule of DNA is a double helix formed from two complementary strands of nucleotides held together by hydrogen bonds between G-C and A-T base pairs.</h2>

Explanation:

<h2>The information carried by a DNA molecule is in Genetic information resides in the order of the nucleotides on a DNA molecule. ... They hypothesized that there must be a code that linked the nucleotide sequence in a gene to the amino acid sequence in a protein. Each nucleotide code is called a codon.</h2>

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

(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.

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.

Which of the following is true regarding tissue?

Natasha2012 [34]

Answer:

<em>True: </em><u>b) Tissue is a group of specialized cells that work together for a common function and form organs.</u>

Explanation:

Cells are the smallest units of life, they may be either unicellular or multicellular. Unicellular organs have a single cell capable of carrying out all of the functions necessary for its survival. Multicellular organisms are more complex, and require the work of multiple different cell types.

Their cells become differentiated- where they undergo certain processes to become specialized, and gain maturity. Groups of specialized cell types form tissue; these each have varying functions over time. Organs consist of two or more tissue types that are specifically organized to carry out a function.
