Which organic molecule provides instructions for the construction of proteins inside organisms?

The tree includes the most recent common ancestor of all living species of bears (branch point 1). what does this tell you about

inessss [21]

If we take a look at the phylogenetic tree of bears presented in the picture above, we can see that the branch number one is the common ancestor to all living bear species, which means that the whole group has a uniform origin. and the phylogenetic tree has a root.
Therefore, the group is monophyletic, not <span>polyphyletic ( meaning that the whole group has the same origin) and not paraphyletic ( there is no group that has been excluded from the tree).</span>

maw [93]

Complete Question:

1. Organisms don’t all reproduce the same way. However, by comparing the ____ of these organisms, many similarities between them are ____

2. of these organisms, many similarities between them are revealed. These similarities suggest that they’re ___ linked. This type of study is called developmental biology.

Group of answer choices.

A) Cells B) Embryos C) Mode of reproduction D) Evolutionarily. E). Revealed.

Answer:

embryo; revealed; evolutionarily.

Explanation:

Reproduction can be defined as a biological process which typically involves living organisms producing an offspring.

Basically, there are two (2) methods of reproduction and these are;

I. Asexual reproduction: it involves the cloning of a living organism to produce an offspring because there is only a single parent.

II. Sexual reproduction: it involves the combination of the genome (gamete) of a male and female living organism during fertilization.

It's a fact that all living organisms do not reproduce the same way.

However, by comparing the embryo of these organisms, many similarities between them are revealed. These similarities suggest that they’re evolutionarily linked.

Hence, we refer to this type of study as developmental biology

Why cloning is considered as unethical? <br>

vredina [299]

Answer:

Because the risks associated with reproductive cloning in humans introduce a very high likelihood of loss of life, the process is considered unethical. There are other philosophical issues that also have been raised concerning the nature of reproduction and human identity that reproductive cloning might violate.

What role does the MutL protein play in DNA repair? (5 POINTS) It performs a proofreading function, similar to DNA polymerase, a

Zinaida [17]

Answer:

It recognizes and binds to a pair of "mismatched" nucleotides, preventing their translation.

Explanation:

Mut L protein is involved in mismatch DNA repair. MutL protein is complexed with MutS protein and the MutL-MutS complex recognizes all the mismatched base pairs present in the newly formed DNA strand. The complex can not recognize the "C-C" pairs. MutH protein joins the complex.

The MutH protein also has a site-specific endonuclease activity and cleaves the unmethylated DNA strand towards the 5' end of the guanine base in the GATC sequence to mark the strand for DNA repair. In this way, MutL protein, along with MutS and MutH proteins mark the mismatched DNA bases for repair so that they are not translated into a faulty protein.
