Sunscreen is the best, and most efficient way to avoid DNA mutations. UV radiation causes thymine dimers in the DNA complex, so limiting UV radiation is key to avoiding DNA mutations.

Sunscreen is the best, and most efficient way to avoid DNA mutations. UV radiation causes thymine dimers in the DNA complex, so limiting UV radiation is key to avoiding DNA mutations. X-rays are not good for you, but they are usually necessary. Avoiding protective shields would increase the damage done by x-rays. Using a tanning bed would also increase UV radiation damage.

Do we classify viruses as living? Give support for both the yes and no arguments.

dolphi86 [110]

Im going to start off with an example:
A seed may not be considered, Yet it has potential for life and it may be destroyed. In this regard, viruses resemble seeds more than they do live cells.They have a certain potential which can be snuffed out, but they do not attain the more autonomous state of life.

So for your answer.
Yes: Viruses have the potential to life. And can flourish.
Or
No: Viruses can be destroyed. Which means it will not get the potential to life.

But
There are always more viruses to the potential to life, some may be destroyed and some may get the potential to life.

The primary function of the chromosome is to?

aleksandrvk [35]

Explanation:

Chromosomes store genetic information.

All the genetic information within the eukaryotic cell is preserved as helical DNA within the nucleus. This DNA is tightly wrapped around histones as chromosomes.

Further Explanation:

DNA sequences contain genes that may have different forms called alleles. The genotype of DNA is transcribed into mRNA and subsequently translated into amino acids that are linked together by rRNA to form proteins that form the phenotype of an organism. Mutations in the DNA sequences affect the corresponding mRNA and therefore the encoded protein

Spontaneous changes that occur within the genome during the cell division process, called mutations. These errors occur as copies of DNA are produced inside the cell; mutations can range from small modifications, called single nucleotide polymorphisms, to large-scale deletions and multi-gene additions.

Problem: Multiple Alleles

yulyashka [42]

Answer:

PHENOTYPE OF MOTHER -O BLOOD GROUP

GENOTYPE OF MOTHER -i/i

PHENOTYPE OF FATHER: AB BLOOD GROUP

GENOTYPE OF FATHER: A/B

THE OFFSPINGS WILL HAVE BLOOD GROUP EITHER A OR B .

THE PHENOTYPES OF OFFSPRINGS WILL BE EITHER A OR B .

THE GENOTYPES OF THE OFFSPRINGS WILL BE EITHER A/i FOR BLOOD GROUP A AND B/i FOR BLOOD GROUP B.

Explanation:

WHAT IS MULTIPLE ALLELES?

GENES WHICH SHOWS MORE THAN TWO ALLELIC FORM ARE CALLED MULTIPLE ALLELES. ABO BLOOD GROUPING IS CONTROLLED BY MULTIPLE ALLELES.

CROSS

MOTHER × FATHER

PHENOTYPES O × AB

GENOTYPES i/i × A/B

GAMETES i A B

F1 GENERATION A/i B/i

(GENOTYPES)

PHENOTYPES A AND B BLOOD GROUPS
