Answer:

DNA is a long polymer with deoxyriboses and phosphate backbone. Having four different nitrogenous bases: adenine, guanine, cytosine and thymine. RNA is a polymer with a ribose and phosphate backbone. Four different nitrogenous bases: adenine, guanine, cytosine, and uracil.

dna deoxyribonucleic acid

RNA - ribonucleic acid

1. The difference between DNA and RNA. The composition of DNA includes deoxyribonucleotides, the composition of RNA - ribonucleotides.

2. Nitrogen bases in the DNA molecule - thymine, adenine, cytosine, guanine; instead of thymine, uracil is involved in RNA.

3.DNA is a matrix for transcription, it stores genetic information. RNA is involved in protein synthesis.

4. DNA has a double helix; RNA is single.

5. DNA is in the nucleus, plastids, mitochondria; RNA - is formed in the cytoplasm, in the ribosomes, in the nucleus, its own RNA is in plastids and mitochondria.d mitochondria.

Sientific method hypothesis

Assoli18 [71]

The process of the scientific method involves making conjectures (hypotheses), deriving predictions from them as logical consequences, and then carrying out experiments or empirical observations based on those predictions. A hypothesis is a conjecture, based on knowledge obtained while seeking answers to the question.

Name the major functional groups and describe it the chemical properties of the organic molecules in which they occur.

Vinvika [58]

<span>Each type of organic molecule has its own specific type of functional group. Functional groups in biological molecules play an important role in the formation of molecules like DNA, proteins, carbohydrates, and lipids. Functional groups include: hydroxyl, methyl, carbonyl, carboxyl, amino, phosphate, and sulfhydryl.</span>

This is an animation of gel electrophoresis. which of these dna molecules is the shortest?

STALIN [3.7K]

In electrophoresis, the molecules travel between the positive electrode and the negative electrode carried by the current that is generated between them.
As seen in the image below, short fragments, due to their smaller size can travel faster than the longer fragments, so the fragments that have traveled the furthermost are the shortest. (marked E in the image)

Free earlobes are dominant over attached earlobes. What is the probability that a woman with attached earlobes (homozygous reces

AVprozaik [17]

<h2>The correct answer is explained below:</h2>

Explanation:

According to the question, free ear lobes are dominant over attached ear lobes.
Let the allele for free ear lobes be represented by F.
Let the allele for attached ear lobes be represented by f.
The genotype of the homozygous recessive woman (mother) having attached ear lobes is : ff.
The gamete produced by the woman is: f.
The genotype of the heterozygous man (father) with free earlobes is: Ff.
The gametes produced by the man are: F and f.
Mating the man with the woman we get the following offspring,

F f

f Ff ff

Phenotype Free ear lobe Attached ear lobe

The genotype and the phenotype of the probable children obtained is represented in the Punnett square above.
The probability that the parents would produce children with attached ear lobes is = $\frac{1}{2}$ .
