An original DNA strand has the following base sequence:

2 answers:

4 0

The base sequence that would be produced through DNA replication would be UGCA. RNA contains three of these bases - (A),(C), and (G) but not (T). Uracil (U) is found in its place and complements adenine (A) instead. I hope my answer has come to your help. God bless and have a nice day ahead!

Answer:

TGCATTCGA

Explanation:

The DNA replication causes formation of complementary bases to its original nucleotide bases.

Here the available nucleotide base is

ACGTAAGCT

The complementary base pair are -

1. Cytosine (C) pair up with the guanine (G) thorough three hydrogen bonds

2. Adenine (A) can pair up with thymine (T) thorough two hydrogen bonds

Thus, for the given nucleotide bases the complementary bases are - TGCATTCGA

To construct a mapping cross of linked genes, it is important that the genotypes of some of the gametes produced by the heterozy

FrozenT [24]

Answer:

False.

Explanation:

Linked genes are the genes that are present on the same chromosome and can undergo the process the recombination. The recombinant progeny are obtained by the crossing of the linked genes.

The recombinant frequency and map distance can be deduced by the mapping of the linked genes. The genotype of the heterozygote cannot be deduced by examining phenotype and sometimes the recombinant progeny is completely different from the parents as well as from the heterozygotes.

Thus, the correct answer is false.

Identify each event as the result of mechanical weathering or chemical weathering.

kow [346]

<h3>The following events are identified as chemical weathering:</h3>

The minerals in a marble statue react with water to form acids and pores in the structure.
The rocks in a region are streaked orange after being exposed to repeated rains.

Reason:

When the weathering process occurs due to chemical reaction, then it is considered as chemical weathering.

In the first case, minerals of marble statue are reacting with water to cause weathering. In the second case, due to the acidificaion reaction, the change of the color has happened after exposure to the repeated rains.

<h3>The following events are identified as Mechanical weathering:</h3>

A piece of rock crumbles after being constantly thrashed by strong waves.

Industrial runoff forms cracks in a rocky structure in its path.

Reason:

When the rock is broken into simple pieces without any chemical reaction it is considered as mechanical weathering.

In the first cause, due to the abrasion caused by the strong waves, weathering has happened, in the second case industrial run off may be of varying temperature and thus may cause heating or cooling of the rock and causes weathering.
