According to the tree, turtles are more closely related to mammals than to birds. Question 11 options: A) TRUE, because turtles

share a common ancestor, W, with mammals. B) TRUE, because turtles are closer to mammals in the tree. C) TRUE, because the ancestor of turtles (W) is connected to the ancestor of mammals (N), whereas the ancestor of birds (P) is separated by one ancestor (C). D) FALSE, because turtles share a more recent common ancestor with birds than with mammals. E) FALSE, because turtles are much more primitive than mammals.

Answer:

D) FALSE, because turtles share a more recent common ancestor with birds than with mammals

Explanation:

There is much evidence about the genetic relationship between birds and reptiles, some physiological, such as the fact that both excrete uric acid and the circulatory system of birds is very similar to that of crocodiles, for example.

In addition, both lay eggs and in them there is the internal amniotic fluid, which nourishes the embryo.

Much scientific research indicates that the birds are related to prehistoric reptiles that had feathers, elongated claws and some also had the ability to fly.

Answer:

DNA Replication:

Replicate the following strand of DNA:

Original DNA: A T G A A C CA T T C A G T A T G G

Complementary DNA:

Remember that the complimentary base pairs in DNA are Adenine-Thymine and Guanine-Cytosine, or A-T and G-C. This means that if the original sequence is:

A T G A A C C A T T C A G T A T G G

Then the compliment is (replace with the opposite base pairs):

T A C T T G G T A A G T C A T A C C

Transcription:

Transcribe the DNA to make an mRNA molecule

COMPLIMENTARY DNA:

mRNA Molecule:

So if our complimentary DNA (antisense stand) is T A C T T G G T A A G T C A T A C C then to transcribe, we basically create another complimentary strand, but for mRNA, we use Uracil instead of Thymine:

A U G A A C C A U U C A G U A U G G  

Translation:

Translate the mRNA into the corresponding amino acids.

mRNA MOLECULE:

AMINO ACID:

Using the DNA sequence provided, determine the amino acids.

Next, take each codon (3-base set) to the table and record the corresponding protein:

A U G = Methionine (start)

A A C = Asparagine

C A U = Histidine

U C A = Serine

G U A = Valine

U G G = Tryptophan

ORIGINAL DNA: A T G G G T C T A G C G A A A G A T

Complementary DNA:

mRNA DNA Molecule:

Amino Acid:

And we do it all again:

A T G G G T C T A G C G A A A G A T = original DNA

T A C C C A G A T C G C T T T C T A = complementry DNA

A U G G G U C U A G C G A A A G A U = mRNA

A U G = Methionine (start)

G G U = Glysine

C U A = Leucine

G C G = Alanine

A A A = Lysine

G A U = Aspartate
