The remains of fossils give scientists clues as to what the world may have been like a long tome ago. If fish fossils are found on the side of a mountain, there may have been a lake there. If a skeleton is found, they can decide what creature it was.

In monkeys, being playful (P) is dominant to being paranoid (p). A heterozygous female is crossed with a homozygous dominant mal
Sergio039 [100]

Answer:

Pp or PP

Explanation:

Being heterozygous mean you have one recessive gene(a), one dominate (A). Homozygous dominant means you have only dominate(AA). if you use a Punnett square, it would look like this:

       P      P

P     PP   PP

p     Pp   Pp

This shows only Pp, and PP are the possible genotypes.

When asked to analyze a sample of marine life, you notice the animal has an incomplete digestive tract, stinging cells, and swim
lianna [129]

Answer:

The correct option is;

True

Explanation:

The digestive system of Cnidarians is incomplete having only one single opening which is the gastrovascular cavity the representing the anus and the mouthof the Cnidarians

The hollow body of the Cnidarian polyp which allows water through has tentacles at the top bearing cells meant for stinging

A prey caught by the tentacles is drawn in to the mouth and ingested

The Cnidarians are able to attach to surface due to their attachment adapted lower end

The correct option is therefore true.

What peptide would be made by translation from a synthetic mRNA made of the repeating dinucleotide CGCG…?
RSB [31]

Answer:

The question lacks options, the options are:

A. a polymer of arginine plus a polymer of alanine

B. the peptide Met–Arg–Ala–Arg–Ala…

C. a polymer of alanine: Ala–Ala–Ala…

D. a peptide containing alternating arginines and alanines

E. a polymer of arginine: Arg–Arg–Arg…

The answer is D

Explanation:

Translation is the second process of protein synthesis (gene expression) where the mRNA molecule produced during transcription is used as a template for the synthesis of amino acid sequences, which species a particular polypeptide.

The nucleotides in the mRNA are read in a group of three in the ribosome. This triplet nucleotide is called CODON. Each codon specifies a particular amino acid and a collection of all codons constitutes the GENETIC CODE. Hence, in a case where dinucleotide CG is repeated in a sequence. The sequence will read:

CGC GCG CGC GCG CGC GCG..........

In the genetic code, codon CGC and GCG codes for arginine and alanine amino acids respectively. Therefore, if the CG dinucleotide keeps repeating, the nucleotides will be read three at a time, and the amino acid sequence will alternate between those two amino acids (Arginine and Alanine).

So we would have a peptide sequence looking like:

Arg-Ala-Arg-Ala-Arg-Ala-Arg...........
