Answer:

1) Since all the important tissues like the sensory and nervous tissues have been concentrated on the head, a damage to the head will lead to a damage to important organs.

2) The animal would not be able to see activities taking place behind the head.

Ipatiy [6.2K]
1. During DNA elongation, polymerase enzyme adds new, free nucleotides to the three prime end of the newly forming strand, elongating it in  five prime to three prime direction while the telomerase protects the important genes at the end of the chromosome from been deleted as the DNA strand shorten during DNA elongation.

2. During DNA elongation, helicase enzyme separates the double stranded DNA  into single strand by melting the hydrogen bond that holds the DNA molecule together thus enabling each strand to be copied while the telomerase acts by preventing the telomere from been deleted during elongation.

The genetic code was originally deciphered, in part, by experiments in which synthetic polynucleotides with repeating sequences
Leni [432]

Answer:

Translation is the process in which ribosomes in the cytoplasm or endoplasmic reticulum synthesize proteins. The process starts where the mRNAs (messenger RNA) copies the DNA and sends this message to the ribosome. In the ribosome for each triplet of nucleotide an amino acid is bond to the growing chain of amino acid that will eventually form a protein.

You can look up for the translation for the genetic on the internet. Which tells you which triplet codifies for an specific amino acid.

If the code reads. CGC GCG CGC GCG etc.

The result would be an a peptide/protein containing alternating arginines and alanines, because CGC codifies for Arginine and GCG codifies for alanine.

Which mutation is an example of an insertion mutation?
Burka [1]

Answer:

d. AAU CCG CAU UGG A​

Explanation:

A mutation is any change or alteration to the sequence of a gene. There are, however, different types of mutation depending on how it occurs in the gene. One of these types is INSERTION MUTATION as mentioned in this question. Insertion mutation is a type of mutation in which one or more nucleotide base is added to the sequence, hence, changing the reading frame of the original sequence.

In this question, the original mRNA sequence is given as: AAU CCG CAU GGA.

An insertion mutation will cause nucleotide base(s) to be added to this sequence, which will be noticed by an increase in number of bases in the sequence.

The correct answer is: AAU CCG CAU UGG A​. In this mutated sequence, nucleotide "U" has been added to the sequence.
