Anna007 [38]3 years ago
3 0

Answer: Semi-conservative replication means that during DNA replication, the two strands of nucleotides separate. Both strands then form the template for free nucleotides to bind to to create the two identical daughter strands. Hence each daughter strand has half of the DNA from the original strand and half newly-formed DNA.  brainliest

Which of the following molecular structures contain codons?A) tRNAB) rRNAC) a proteinD) mRNA
KiRa [710]

Answer:

D) mRNA

Explanation:

In mRNA, genetic information is written from four letters, which correspond to the nitrogenous bases. This is called ogenated codon; A, C, G and U, forming long sequences of triplets. In mRNA, each of these consecutive, non-overlapping triplets is called the codon, which undergoes transient binding to the complementary aminoacyl-tRNA within the ribosome insertion sites during the translation process to establish initiation, elongation, and completion of polypeptide formation, plus a punctuation symbol.

Zinaida [17]

Answer:

Cells, tissues, organ, organ systems, organism

Explanation:

All living organisms including Lisa as used in this question is made up of fundamental and basic unit called CELLS.

In multicellular organisms (more than one cell), these cells undergo multiplication by dividing repeatedly and the ones that perform similar functions forms the TISSUE. For example, in humans like Lisa, we have the blood tissue formed by blood cells performing similar functions e.g erythrocytes, leukocytes etc.

The tissues that work together to perform a certain function groups together to form an ORGAN. An organ performs a specific function in the body. Examples of organs in a living organism like Lisa is heart, Kidney, liver etc. These organs, whose, functions are in synchrony collectively forms the ORGAN SYSTEM, which helps maintain the internal environment of an organism. Organ systems include; circulatory system, digestive system etc. Each organ system is made up of certain organs.

The collaboration of many organ systems working together ultimately forms the full ORGANISM like Lisa who is a human.
